Are there viruses that delete "My Documents", or other malware that target that folder? And, the funny part, if you rename it, will it help? I've seen a spyware folder installed in My Documents.
Oh, I see... I have a question. Are there any viruses that target destruction of the My Documents folder, and if so, would changing the name of the folder help any?
There aren't really a lot of viruses focused on destruction anymore. A lot of them are focused on opening holes for adware and spyware.
Renaming the folder won't help because the virus would just target the directory. Just get a good firewall and you will be fine, and if you already have it do what Computer Genius said.
