Have a Windows 7 machine that was running slow. It would have multiple copies for explorer.exe in the taskmgr. It had an old copy of Symantec Anti-virus which last updated the virus definitions in 2013.
Removed old Symantec. Installed new Symantec. Performing much better now. I still get two or three explorer.exe running, before it was more like 7 copies.
Did a full scan of the computer & Symantec found nothing.
Just leaving the computer on & connected to the Internet. After a few minutes when I return to look at the screen, there is a warning from Symantec that it detected suspicious activity from "Trojan.Cidox Activity 3"
It does not have anyway to remove this virus. In the logs you can see IP addresses that it was attempting to communicate with that Symantec has stopped.
Been on Symantec's web site and they identify this has a virus, but there are no removal steps provided.
How do you get rid of this thing?
