Hello all,

Due to a virus detected at work on about a gazillion Windows machines, I decided to do a precautionary scan of my Linux laptop. Surprisingly, I ran across the following output from clam:
Code:
//home/cobbr/vmware/WinXPPro/Windows XP Professional-f001.vmdk: Linux.Lion worm FOUND


So, being cautious, I checked my chkrootkit output and found noting (output below)... Are these signatures normal from virtual disk files that VMWare uses, or could a coincidental series of bytes in the file have triggered this find?

Thanks in advance!
Randy

I also did a scan while the XP OS was running within VMWare, and it also found no virii...

Anyone have any idea if I should be worried about it or not?

Isn't that supposed to be a Linux worm? Then it should not be able to run in the XP VM. In which case I think it probably is a false alarm, since the VM disk file is not executable...
