google uses cookies, to track and log all of ur surfing behavour, in there db. This can then be requested by companies or governments to add target. Or target u for software piracy. Or even investigate u for suspected terrorisom etc.

I am sure other companies do the same.

So cookies are not entirley harmless and should be deleted on a regular basis. If u r using Firefox - just set the clear private data option to clear everytime u close firefox. IE has a similar function but u have to run it manually.

I might have to agree to what The_Lestat said about clearing private data. But then, that is part of safe surfing habits. So, it should have been done often, not until a scan tells you to.

Cheers!
