I am an administrator in my office..a small firm without those expensive anti virus software/server. About 20 coms are connected to the network and all of them are capable of
1. accessing data files in the server
2. P2P, messenger services
3. browsing internet
Recently one of the computer is infected with worm W32.Sonahad.AI (the symptoms match the most of its description). Shortly after that at least 5 other coms are infected as well. The othe 15 is undetermined for this time being (if the r infected, it's not too serious).
Anyway one brand new CPU arrive for the new staff. I plug it into the network and the staff runs all the services above. I've installed AVG anti-virus free edition on the com and assumed it is safe to plug it into the network. Below is the HJT log of the com after being plug into the network. Please advise if this com has been infected. Thanks in advance.
