Spyware can be more than an annoyance. Poorly programmed spyware can interfere with other programs and can even cause system instability. Privacy issues are at stake as well.
This type of software is often installed without a user's consent and often can't be uninstalled without special tools. When distributors use tricks and deception to install uninvited software, trust is destroyed.
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 your system does get hit with a spyware attack, all is not lost. There are several software utilities made for getting rid of it. These programs have a database of known spyware that gets updated on a regular basis as new ones are found. They'll scan your computer to see if anything from this database is installed on it.
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 kinds of spyware are notoriously difficult to get rid of. They may make changes to your Windows files that help them hide from the scanners. On occasion, you may need to delete them manually to be sure they're gone.
Needless to say, this should be performed only by skilled users. Deleting the wrong files can damage your programs and even your operating system.
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).
And of course, always be aware of the risks before you accept any free offers for software on the internet. You never know what the real cost is for that free program.
