I have a worm or malware virus that is making it's way through my network. I have very little information about it as conventional scans do pick up any infected files. There are a specific set of symptoms though. Network connectivity ceases on the infected machine. When you run IPCONFIG from the command prompt the "connection-specific DNS Suffix:" shows a line of random characters (brackets, numbers, smiley faces, etc.) and the internal speaker beeps. A /release /renew temporarily returns connectivity. Combofix reports some deleted files. Symantec antivirus is up to date and real time scanning is on along with windows firewall.
If anyone has seen this before and knows of a removal tool or some manual removal instructions it would be greatly appreciated.
