Can anyone help with a virus problem please ? A friend opened an email attachment called SMS, it was a ZIP file. According to AVG the file was clean but now there are problems with his computer. First there was a message that the computer would shut down in 40 sec and it did. After rebooting, access to any kind of security software seems to get blocked e.g Microsoft updates, starting firewall, won't read SP2 cd. OS is XP Pro. Any advice on what to do next appreciated.
