Using Free Software Sites To Get The Applications You Need

No matter which type of computer operating system you own, it can be very confusing deciding what software you should purchase. Since updates continually take place, you definitely don’t want to spend money on something that is going to be changed in the near future. Software can also be quite expensive, so you want to make sure you are getting the best possible price.

At free software download websites, you can take advantage free software for your computer system. Many free software sites contain a wide variety of applications for computer system maintenance and security. For those of you who depend on your computer for more than entertainment, you know how vital that is. Other types of software available include billing, system recovery, and software to help you develop your website.

Since software is so expensive, why not check out what free software sites have to offer for free before you spend your money on it? Chances are you will find a variety of software products available that will work well for you.

One of the disadvantages of free software sites is the risk of spyware or adware. This problem is easily avoided by using sites such as CNET's download dot com, which does not allow any software with adware or spyware. Many other sites also use a scanner system to alert you if a piece of software contains any adware, spyware, viruses, or other unwanted components.

Another possible disadvantage of free software is the lack of support available. This is something you should consider – if the software you need is crucial to you and you will need good support, you may need to buy the software. If you can make do with lesser levels of support, free software may be the best way to go, though. Many free applications do offer support via user forums and online help centers.

How Computer Viruses Work and How to Protect your Computer

Many people are afraid of tinkering with their computers because of the
fear that they might inadvertently introduce a computer virus into the
computer system.



Computer viruses have become the technological bogeyman that scares
computer users all over the world. We have all heard of how dangerous
computer viruses are and how it can damage your data. Of course, aided
by the bloated images Hollywood movies paint with regards to computer
viruses, a big majority now have this insane (but mostly unfounded)
fears about it.



It is true that computer viruses are dangerous. Anyone who has lost
vital information in their computers because of a computer virus will
know how big a damage it can cause. But computer viruses are not these
insidiously little pieces of code that could wreak havoc on the world.
If you know what to do when you get a virus in your computer then you
can definitely limit, if not totally stop, the damage it can cause.



But what is a computer virus? Well, it is a software with a small
imprint that would usually attach itself on to a legitimate program or
software. Every time this program is executed the virus is also
executed and it tries to reproduce itself by attaching to other
programs or it immediately starts affecting the computer. A computer
virus and email virus basically have the same modus operandi, the
difference though is that an email virus would attach itself to an
email message or automatically send itself using the addresses in the
address book in order to infect the people who receive the email.



A computer virus is usually embedded in a larger program, often a
legitimate piece of software. The virus will be run when the legitimate
software is executed. The computer virus would load itself into the
memory of the computer and then it will seek out any programs where it
can likely attach itself. When a likely program is found then the virus
would modify the file in order to add the virus’ code to the program.
The virus would usually run before the actual legitimate program runs.
In fact, the virus would usually perform the infection first before it
commands the legitimate program to run. This process is so fast that no
one would even notice that a virus was executed. With two programs now
infected (the original program and the first infected program), the
same process would be repeated whenever either program is launched
worsening the level of infection.



After the infection phase, or even within the middle of the process
of infection, the virus would usually start its attack on the system.
The level of attack can range from silly actions like flashing messages
on the screen to actually erasing sensitive data.



Fortunately, there are steps that you can do in order to protect
your computer from viruses. Among the steps that you can take are:



* The simplest way to avoid a virus is to install a legitimate and
effective antivirus program in your computer. The antivirus program is
designed to look out for any kind of activity that could be seen as
similar to a virus attack or infestation and it automatically stops it.



* You can opt to use a more secure operating system in your
computer. For example, Unix is a secure operating system because the
security features built into it prevents a virus from actually doing
what it is programmed to do.



* Enable Macro Virus Protection in all of the Microsoft
applications resident in your computer. Additionally, you should avoid
running macros in a document unless you have a good idea of what these
macros are going to do.




* Avoid using programs that you have downloaded on the internet especially when they come from dubious sources.




* Never open an email attachment that contains an executable file – these are files with the EXE, COM and VBS extensions.

Some Tips About Software

The term software is generally used for computer software that is an essential part of the computer system. It stores and process all encoded information or computer instructions on PC. Computer software has very vast scope in computer world.

According to computer science and software engineering computer software is all information that is processed by computer systems, programs and other data. Software is completely opposite to hardware, which is used to store or execute the software. Software is loaded into random access memory and then executed in central processing unit. It belongs to machine language that is not easy to understand for the users.

Every operating system has its own software that requires an individual processor. It understands machine language that consists of several groups of binary values, which gives processor instructions and data. Software converts machine language in simple language that enables the users to understand machine language.

Software generates a connection between electronic hardware and data. The user can operate the sequence of data instructions with the help of software. Software can use any type of data such as output/input. Sometimes the output of software can be input for another software. Software provides an interface between hardware, data and other software.

Software can be divided in three classes such as system software, application software and programming software. System software enables the users to run computer hardware and computer system including operating system, device drivers, diagnostic tools, servers, windowing systems and some more.

Users can perform one or more tasks simultaneously with the help of application software. With the help of application software, they can perform all applications like office suites, business software, databases and games. Whereas the programming software offers some functional tools that enables the programmer to write difficult computer programs. Programming software provides some useful tools like text editor, compiler, interpreter, linker and debugger etc.

After installing software a computer can operate that vary software. Application software passes the instructions to system software and then computer program executes on computer.

Free Antivirus Scan

If you are looking to protect your PC but want to make sure that you are using a good product, why not take advantage of a free antivirus scan? There are two routes that you can take with this. Some companies allow a free scan of your computer but you will need to pay for the full antivirus product to remove any problems found. The second option is to download a free product that will also remove viruses.

The companies that allow a free antivirus scan include Bit Defender and Panda Security. Both of these companies have a good reputation in the field of creating computer security products. The reason they allow you to carry out a free scan is for you to get a feel for how simple their products are to use. The hope is that you then go on to buy the full product.

However, don't rely on this free scan for your antivirus protection. Although it is better then doing nothing, carrying out a scan is only the first step in protecting your PC. You really want a full working product available to you as soon as any virus is encountered on your machine. It is also better to have a product that provides 'real-time scanning'. With this feature, viruses are detected as soon as they try to get on your computer. This is better than waiting to find them on your next manual virus scan.

The second option is to use a totally free antivirus product. These can be downloaded for no charge and will both scan your computer and remove any problems that are found. AVG Antivirus is a program that falls into this category. It also provides some real time scanning ability.

Protecting your PC is a serious business. Using software that will provide a free antivirus scan is a great first step in protecting yourself. You will also need to decide what software to use to remove viruses and provide real time protection for your computer.

TIPS TO PREVENT VIRUS ATTACK

Virus is the worst of malwares (rogue programs) that causes serious havoc to your computer system. A virus is self-replicating and affects computer hardware, software, and even the Operating System. Viruses are designed to replicate themselves and to elude detection from anti-virus software, so without a good antivirus software it might be impossible to dig them out of your computer system.

Computer virus is an executable program written with the intention of causing a wreck to your computer or network, and because viruses are programs, they are loaded into computer memory, executed and instruct the computer to perform the actions dictated by the virus.

A virus can instruct infected computer to re-write the virus onto other computers in the network thereby spreading the virus from one computer to the next. A virus payload may also delete files from hard drive, write itself to another program, or even spread across the internet through file attachments.

Virus may fall into one of these categories;

1) Parasitic - infects executable files or programs in the computer

2) Bootstrap sector - infect the boot sector of the hard disk where OS start-up files are stored on the first partition.

3) Data file - These types of viruses can open, manipulate and close data files, and are usually written in macro language. They mostly affect Microsoft Office Word document

4) Companion - this type of virus creates a program with same name as another program that already exist on the computer, tricking the computer to run the rogue program instead of the real program.

Protect yourself by backing up your computer regularly so that in case there is an infection you can restore your system from the back up. It is also important you have very reliable anti-virus software on your machine. Good anti-virus must self-updates its database from time to time so that it can prevent you from a new attack.

4 Steps To Clean A Computer From A Virus

Having a virus on your computer can cause your
computer to slow down, install spy ware and ad ware, or let hackers
into your computer to steal your information. Knowing how to clean your
virus-infected computer is easy. Here are some tips to show you how.

As
soon as you think your computer might be infected you should disconnect
your computer from the Internet and any networks you computer might be
on. This is to ensure that the virus does not spread to other computers.

If
you have an anti-virus program installed make sure it is updated first
then run a full system scan. The anti-virus might not detect the virus
if the program is not updated.

Some anti-virus programs will
detect the virus, but will not be able to remove it. If that is the
case, you can get a different program by downloading it from a computer
that is not infected or you can go to your local computer store and get
a different one there.

Most anti-virus programs will ask you to
restart you computer after it is finished scanning. Once you restart
you computer run another scan to make sure that the virus is gone. When
you restart your computer make sure that it is still disconnected from
the Internet and other networks. Once you are sure that the virus is
gone, reconnect the computer.

The best way to combat against
viruses is to be cautious of programs and files you and other people
that use your computer download. Do not open any e-mail messages or
attachments you do not recognize. Get a good anti-virus program that is
updated frequently and run system scans regularly.

10 smart things to against brutal computer virus

Virus infection on your computer may cause a very serious damage and even loss on your business. You can just imagine it may wreck your system registry or your entire computer (with all your receivables data on it!) or all your HTML programs! It will come to total black out screen, it will not boot at all. But that is actually the worse scenario that may happen. Are you going to wait for this worse scenario in your life to happen? I guess NOT, right?

Here are the 10 smart ways that I personally do to protect my computers against viruses, malicious dialers and spywares.

(1)If you are using Windows XP, always turn on the firewall.

(2)Always run all necessary latest updates & service packs (all windows! including all your programs & software!---keep them updated)

(3)Run your anti-virus program everyday (some do it every week) There are many virus programs that you can get for free scanning.

(4)Run your anti-spyware/adaware once a week (I run Spybot Search & Destroy & Lavasoft Adware Personal --- they are shareware, meaning it’s free!). What I do is that, I run the Lavasoft Adware first, then run the Spybot Search and Destroy (I also run it with “immunize” tool). These two tools are always on top of my desktop for easy access.

(5)Turn on the pop-up blocker – this feature is available on Windows XP (you can see this under tools>Internet Options >Privacy>click Block Pop Ups. In addition to this, I also download another pop up blocker, the Google Toolbar. I find their pop up blocker the most effective in blocking pop ups.

(6)Never open mails that are suspicious to you or not known to you. If they are in your bulk mail, send it back to your provider as “spam”! I never enable my bulk mail. I automatically delete emails from my bulk mail.

(7)When using messenger (IM) services, be very careful with files being sent through instant messenger. Rather choose to have it emailed it to you. Most of email services now has virus check and clears it if the file has virus or not.

(8)Be very careful when downloading files or any programs from the internet, pay attention on the instructions while downloading it. Downloading may sometimes cause error on the system registry or the entire computer system (one example, my nephew got his computer badly infected with viruses because of heavy downloading of games and music! – I guess!)

(9)Be careful with files that come from a floppy disk or any other external storage when you open it in your CD ROM of floppy drive. You should know its source, or better yet, when you insert it, have it scanned with your anti-virus program before you open the files.

(10)Run defragmentation, disk clean up, registry scanner at least once a week. You can find defragmentation by simply pointing your mouse on drive C: (which is usually the hard disk main logical drive)> right click the mouse>click on properties>click on tools>click on defragment now!

There are so many shareware on the internet that you can get for free! (that is the reason it is a shareware!). Keeping your computer healthy can make you more productive (if you have a business!) or it will make you enjoy more surfing and browsing the internet!

REMOVE SPYWARE FROM YOUR COMPUTER

Not everything on the internet is safe for your computer. There are programs on the internet called spyware which are looking to make it onto your computer somehow. When spyware gets on your computer your privacy is at risk because spyware reports back to the place it comes from what you are doing. Don't put yourself in the position of risking your personal data.

How do you get spyware

Spyware comes from visiting unsafe websites or downloading unsafe files. Are you sure you know that a website is safe? If you download something from an unsafe website, they could be sneaking spyware onto your computer without you knowing. Once the spyware software is on your computer you most likely won't even realize you were infected.

What can it do to your computer

Because spyware just wants information, it doesn't care how it gets it. This means that it can cause computer problems in the process. Do you notice more errors than normal or your computer taking long to do things? This is one of the effects of having a spyware infection.

What can you do

The best thing you can do to get rid of spyware is to run a scan. There is plenty of free spyware scanners available for you to use. These will search your computer for known spyware threats and tell you how to remove them. It is important that when spyware is found you remove it immediately. You don't want to put yourself at more risk by leaving it on your computer.
Don't wait any longer! Scan your computer with a free spyware scanner and get rid of the spyware!

TIPS TO FIX UNRELIABLE WIRELESS CONNECTION

Generally speaking, wireless computer connections are reliable. However, nothing is perfect, and sometimes you may lose your connection or experience a weak signal. There are many factors that impact the reliability of your wireless connection.

For example, if your wireless adapter is too close to a 2.4 GHz wireless telephone, you may notice a decrease in your computer’s wireless single strength. Why? Because the phone and the computer reside on the same frequency and can interfere with each other’s performance.

Handy Repair Checklist for Wireless Interruptions

1. First check to see if your cable or DSL is actually working. Usually located in your basement, most modems have four lights. You have a live Internet connection if the “data” or “status” light is on. If it’s off, or flashing, your cable is out.

2. If your cable/DSL is working, then reboot your computer. Sometimes, if your cable/DSL goes out for even 10 seconds, your computer and the wireless router may no longer be able to talk to each other. By rebooting your computer, a new IP address is assigned, allowing them to once again communicate.

3. If your desktop is wireless and you’ve moved the wireless adapter [the box that sits next to the computer with antennas], then you may need to move the adapter until you find a stronger signal.

HOW COMPUTER CONTROLLERS WORK

Controller

A computer system contains a first and second memory controllers; a first and second computer memory associated with the first and second memory controllers, a memory space; and firmware under control of which the computer system generates data that enables the first memory controller to use the first computer memory, saveing the data in the memory space, copies the data to the first memory controller, causing the first memory controller to use the first computer memory, and uses the first computer memory to initialize the second memory controller to use the second computer memory.

Reset

The computer firmware initiates a reset after saving the data; the computer system determines whether a current reset is firmware initiated; if the current reset is firmware initiated, the computer system copies the data to the first memory controller having the first memory controller to use the first computer memory, and uses the first computer memory to initialize the second memory controller to use the second computer memory; and if the current reset is not firmware initiated, the computer system generates the data that enables the first memory controller to use the first computer memory, and saves the configuration data in the memory space. Determining how much physical computer memory is present and useable, the memory controller uses the computer memory. To do so, it gathers type, size, speed and memory attributes from the memory modules and programs the memory controller accordingly. Once the memory controller has been configured, It will program a setting in the memory controller that triggers the memory controller to initialize the memory modules. Therefore, the complete configuration information is formatted and assembled, but not yet programmed into the memory. In this manner, it configures information with "virtual" registers having a one-to-one correspondence with the actual registers that are in the memory controller.

There are hundreds of Adware deletion programs on the push. Your best bet is to go to a place like Spybot Download It lists the best Adware Removers presently on the push. Or just google the speak "adware remover". Like I said, you'll find hundreds. Some are good, some aren't. Free Spybot is a great situate for you to see which ones work, but I know some of you just like to google, and that's approval too ;).

HOW TO SPEED UP YOUR COMPUTER

Do you want to learn how to fix a slow computer? Most likely you are a computer user, but have no idea about why your computer starts to slow down over time. Having experienced a slow computer myself, I was finally able to clean up my slow computer and make it run like brand new again.

What I Did To Fix My Slow Computer

To make your computer run faster again, you will need to repair your registry files. They are the files in your computer registry that give the software and hardware the instructions to run properly. A computer registry filled with errors will cause the computer to slow down, because the applications get stuck while running. Another result of a bad registry is the frequent freezing of the computer.

How To Fix Your Computer Registry

The computer registry is a component of the computer that is not regularly talked about, yet it is one of the most important. Most people have no idea about a computer registry, even after years of using their own PC.

Fixing your computer registry requires you to download a good registry cleaner. Try not to fix your registry by yourself, because any mistakes made may be fatal to the system. The registry cleaner I used managed to detect all the errors in my computer registry, and proceeded to clean up all of them. The whole process took about 10 minutes to complete. To download the top registry cleaner on the internet, visit my website link below to learn more about the best 5 registry cleaners.
