"Backdoor-AMA" virus: WTF?

Sigh. Dad calls; he started his computer and McAfee says the file

c:\windows\explorer.exe

is infected with a “Backdoor-AMA” virus.

But of course, McAfee cannot fix it. It simply recommends he delete the file. Umm… isn’t that kind of an important file?

What do we do? Can I just send him a copy of my explorer.exe and have him replace it?

Click the link for complete removal instructions. But, basically, you can safely delete the virused file.

Information and cleaning instructions are at McAfee. Basically, the “explorer.exe” file it mentions is actually "explorer.exe " – with a space at the end – and can be deleted safely. Read the article about what needs to be cleaned in the registry, too.
