If anyone might be able to provide some assistance, I would be grateful. I have contracted the Backdoor.Optix trojan and I cannot get rid of it. I use Norton AntiVirus and it located the file causing the problem but I cannot delete it. It seems that when my computer boots, a command file (windows.com) is loaded from C:\Windows\System32 and begins a process that runs in the backgroud. So long as the process is running, I cannot delete the file. But when I end the process via the Windows Task Manager, the windows.com file disappears. I cannot remove the Norton warning and multiple scans have failed to properly remove the trojan.

There is also an executable (yahooupdate.exe) that is related but also disappears when I click on it.

Any advice?

Welcome to bleepingcomputer.com, gammapi.
The best thing to do would be the post a HijackThis log, and go from there.

An alternative might be to try doing the deletion in safe mode.


It is possible more is involved than just what you describe, so if
a log is posted, we can check for any additional factors present.
