When your computer suddenly slows to a trickle, chances are you've been infected with tons of spyware and adware. These are programs that are generally downloaded but can be installed, often without your knowledge or approval. Yes they are illegal, but its almost impossible to do anything about it.
Spyware programs range from very benign programs which may try to sell you something - I am sure you've see those annoying popups - to malware which can either damage your computer physically to the point that it stops working - similar to a virus, but not as damaging. Spyware may also take note of your keystrokes or private information which it then emails to the owner of the spyware.
Some tips for avoiding the installation of spyware are:
1. Install good spyware removal software
This is the best way to avoid spyware and adware and it needn't cost you a fortune. There are very good free spyware removal software available. These include Windows Defender, Spyware Doctor, Super Anti spyware, Adware Free 2008.
2. Stay away from Adult sites, warez sites and cracked software
If you download from these kinds of sites, you can almost bet your life on the fact that spyware or adware has been downloaded and installed on your computer.
3. Don't install any activeX components unless you're sure they're secure and not spyware.
A lot of spyware is installed through activeX controls.
4. Never open email attachments without scanning them with a virus scanner first.
This is great tip not only for spyware but for potentially harmful viruses as well.
