Yesterday, my friend sent me a link over MSN, leading to a site called "http://www25.emoprofile.net/emo.php?msn=(my hotmail address)". I went there and my computer ran a file which infected a file in my Windows directory.The infected file is called "HOSTS". I can't seem to find directions of removing it on the internet...I'm running Windows XP, and my anti-virus is AVG Free Edition.I also used AVG Free to move the file to my Virus Vault, where I have three other trojans.The other trojans in my Virus Vault are:Generic3.ASDownloader.Generic.HGTDownloader.Generic3.GNCAny help?
