I am having a problem...Last night I was on Yahoo! messenger talking with a friend of mine, and I went to respond to him, and Norton Anti-virus came up in DOS and said this <br><br>"Found virus on port 2135 sys.backdoor.worm" <br><br> It asked me what I wanted to do..so I thought I quarantine it, so I did. It powered down, then rebooted. On reboot Norton Anti-Virus came up, and said "now quarantining sys.backdoor.worm on file run.exe." <br><br>Now I can't run any files, it says "Cannot find file run.exe, Windows needs this file in order to run files that have a .app extension." <br><br>Can anyone help with this virus, and if anyone could send me the file "run.exe" via E-mail I would really appreciate it! <A HREF="mailto:mmccormick0@yahoo.com">mmccormick0@yahoo.com</A><br><br>spike232
