My computer has slowed down considerably. What is the problem?
The most common cause of is spyware. Download Ad-Aware from http://www.download.com/Ad-Aware-SE-Personal-Edition/3000-8022_4-10045910.html?part=dl-ad-aware&subj=dl&tag=top5 . Install, update and run it to get rid of the adware. Another good program that plays well with Ad-Aware is Spybot. It can be downloaded from http://www.download.com/Spybot-Search-Destroy/3000-8022-10122137.html?part=dl-spybot&subj=dl&tag=but. In both cases, install the program, check for updates to the program, and then run the program. This will remove the spyware that is slowing down your computer.
