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!
