My computer is ridiculously slow. It has no virus, malware or spyware at all because I ran complete scan of antivirus, firewall and antispyware. I also ran the registry cleaner of lavasoft.

I use Avira Antivir classic, Comodo firewall, PC tools Spyware doctor, ad-aware and lavasoft registry cleaner for protection. So if there is no virus, malware or spyware then why is it still so ridiculously slow?

It is an emachines desktop which I purchased in April 2005. It still has windows xp. I am tired of doing computer recovery and re-formatting the hard drive.

I just did the recovery 2 days back. After recovery it is fast but then when 2 to 3 days pass, it again gets very slow.

I talked to emachines technical support and they say i have to add more memory. Why? Why must i add more memory when it is only 3 and a half year old computer?

Can a 3 and a half year old car, have so many problems? Then why PC’s fail after 2 to 3 years only?
i also added a performance enhancer named Boostkit. It is sold by mcafee.

Unfortunately the performance booster also failed. I realize my get wasted. This computer is almost in its grave now.
