Windows 7 ??????.exe has stopped working

[tim23x]

Hello,

I left my Dell laptop running a Sophos anti-rootkit scan overnight. This morning I found six extra windows open, which looked like this:
Link Removed
They were named:

pgrhbx.exe
xcshfl.exe
tvbgvq.exe
bgqrmm.exe
lhftkp.exe
dwrcdn.exe

which looks like six randomly generated letters for the application name. I'm not sure if this is anything to do with the rootkit scan I was running, but I'm a bit concerned by it. Does anyone have any ideas about this? I'm running Windows 7 Prof 64.

Cheers,

Tim
