Hi there.
I have been using Avast for a few months now and I am very happy with it so far.
I ran a scheduled scan tonight and it came up with an issue though, it lists several dll files and states Error: Cannot find the path specified (3)
The files it cannot find are
algo.dll
aswcmnbs.dll
aswcmnis.dll
aswcmnos.dll
aswengin.dll
aswrep.dll
aswscan.dll
Yes that is an old defs folder being cleaned out during avast housekeeping. If these wern’t periodically cleaned out it would take up a lot of hard disk space.
