Not all cookies are harmful and if you delete them you lose their benefits. (Such as auto log-in to PPRuNe for example) The harmful ones are mostly picked up by Ad-aware and other programs but even they miss some. The advice of opening them in a text editor is good - I've found some that contain my own e-mail address that are obviously not welcome in my P.C. I too have noticed spyware coming in from PPRuNe but although Ad-aware snags it as spyware it seems to be innocent enough.
I'm still stuck with some files in my cookies folder that cannot be deleted that are left over from an e-mail attack made against me by some wierdo p*ssed off about me detecting and deleting the spoofing file that he had created on my hard drive. Although they look like cookies, they are obviously something else that got through my firewall in disguise. Any tips on what they might really be is very welcome - I'd like to get rid of them as they seem to be responsible for a lot of boring spam.
