The Avast scan threw up 2 high severity threats in different places. ComboFix.exe was identified as a Win32:Agent-QZQ[Trj], I am pretty sure that this would be classified as false positive, nevertheless I allowed these to be 'Moved to Chest' as I am not using them.
It came up with Two 'Device not ready (21) the first had a path of Disk\\?\Volume{7b1f0c53-0c22-11e0-8aa2-806e6f6e6963}Boot Record , the second of these \\?\Volume{7b1f0c53-0c22-11e0-8aa2-806e6f6e6963}\
A search in the registry threw up 3 occurrences of this key, none of which appeared suspicious except that I could no longer use Castle Cops excellent databases for a thorough check - frustrating
It also identified 8 paths it could not find (3), all involving dll's which were:
algo, aswcmnbs, aswcmnis, aswcmnos, aswengin, aswfidb, aswrep and aswscan
as far as I can ascertain they all belong to Alwil low level software which seems to be linked to Avast anyway....
One last attempt to install MSE on Vista and then it is back to Win7 for a progress check
