Spyware is more than just annoying - it can cause other programs to not work properly and can cause your computer to become quite unstable. Not to mention the privacy issues it brings up.
These pieces of software are generally installed on your computer without your knowledge or consent. They often can’t be removed without some kind of specialized software. If you need to be tricked into installing it, chances are you can’t trust the source.
The best defense against spyware is common sense. Always be watchful when you download software from the internet. Don’t install software from unknown websites that you don’t know if you can trust and be sure you always read through the license agreement. Sometimes the license will disclose that spyware is installed along with the program (although usually not in so many words) but they’re counting on the fact that hardly anyone ever reads the license anyway.
Check for a guarantee that the software is spyware free. This won’t protect you 100%, but it is a good step towards being able to trust a website.
What are the signs of a spyware infection? Odd pop-up advertising, a new homepage when you didn’t change it, new toolbars that you didn’t install or your computer is responding slowly or rebooting randomly all of a sudden, to name a few.
If you find your system bogged down with spyware, don’t give up hope. There are several utilities specifically designed for removing spyware from your computer. They rely on frequently updated databases which contain signature files of all known spyware and adware. They scan all the files on your hard drive and alert you if ‘uninvited guests’ are found.
Many are free, though sometimes the paid versions have more automation features such as removing spyware on receipt rather than requiring a manual scan. None will find every piece of spyware on your system, since they rely on a database which has to be populated according to someone’s judgment. And, one man’s spyware is sometimes another’s welcomed advertiser.
Some types of spyware are exceptionally hard to get rid of. They can make changes to settings on your computer that help to “protect” the spyware from being removed. In some cases, you need to manually delete the files to get rid of them for sure.
This is obviously not something you should undertake unless you’re quite familiar with Windows and working with system files. You wouldn’t want to delete something that renders Windows inoperable.
Once the spyware has been removed from your system, you should run scans on a regular basis to keep it clean. Whether you do this manually or use a program that does it automatically on a schedule is up to you (and your pocketbook).
Of course, you need to always be wary of anything you download. You never know when there is going to be a significant cost to that free software that looks so cool.
