I recently noticed that this type of virus was in my AVG Virus Vault. I believe the filename is prototype.js. Is this safe to delete out of my vault, or is it a file I actually need. Also, I have attached a HijackThis log in case there are any other problems. Thanks for any help! EDIT: I noticed that the previous location that the file was in was the Internet Explorer Temporary Internet Files, so I removed the file, and everything seems to be working fine.
