Is this result normal?

[GUNxSPECTRE]

I did some full-scans and once in a blue-moon, results would be that "The system cannot find the path specified (3)": Here are the file names in question:

c:\program files\alwil software\avast5\defs\10052900\algo.dll
c:\program files\alwil software\avast5\defs\10052900\aswcmnbs.dll
c:\program files\alwil software\avast5\defs\10052900\aswcmnis.dll
c:\program files\alwil software\avast5\defs\10052900\aswcmnos.dll
c:\program files\alwil software\avast5\defs\10052900\aswengin.dll
c:\program files\alwil software\avast5\defs\10052900\aswscan.dll

Does anyone else get these?

On May 17 I did a complete scan and got results like yours. It got my
attention so I did another scan the following day and got similar results.
On the 19th I did another scan and got nothing showing so I don't worry
about that and I don't think you should either. I have not done a full scan
since the 19th and it probably means nothing important. Anyway those files
are part of Avast so don't worry, enjoy the net.

Yes it is normal, if a little strange.

The VPS (virus definitions, defs) updates create new folders after a while older folders are removed in a house keeping exercise as they are effectively duplicates and quite large 50MB+ (see image of the latest VPS/defs folder). So it is possible that at the time you started scanning avast was also cleaning house and the old folder no longer exists.

Nothing to worry about, it happens on occasion. The main thing is that these are just files that can't be scanned and the reason why, not that they are infected/suspect.
