Virus or Spam attack, how to remove ?
Posted on 2007-03-20
I have a serious virus issue in our office
We have windows 2003 standard server running exchange 2003 and a windows 2000 server as a file server. Desktops are running XP and 2000 with Norton/Symantec antivirus corp edition 7.5 and some pc running 10.0
Few days ago a virus hit us (spybot and downloader). Some pc's were rebuit from scartch and put back onto window 2000. The problem i have is this
1. The newly rebuilt pc's once put on the network gets a qurantine message from NAV saying it qurantined downloader and or "i". Does this mean the virus is coming from the outside or is inside the network.
2. When a pc boots up, if the user dosnt login with a few minutes it comes up with "network request not supported" and if i reboot the pc and login again it is fine.
3. On 2000 boxes the network drives "disconnect" after a while.
4. Email runs fine
5. Network runs slow
My feeling is that there is still 1 or 2 pcs with some sort of spam that is spiting out data onto the network. Can you please let me know what tools i can use to remove this and also how to determine which pc's are infected.
Thanks in advance
