I'm currently using windows xp home edition. I've been using it for quite some time and now it's getting quite slow especially when startup. I would like to get rid of the unecessary windows files in c:/windows but I've no idea what file to delete.

I've cleared all the junk programmes but that is still not enough. How can I optimize the performance of my PC.

Notices come up that my home computer has been infected with a virus.

I live in California and called a well known company called the Geek Squad. They said the fee would be about 0.00 to clear it up.

Is that standard fee for home computer virus cleanup? Will pay it if I have to but seems high fee for this problem.

Any other suggestions on how to clean up my computer.
