I appreciate the quick responses.
With regard to the filestamp change, an EXE's timestamp doesn't change just from moving a file. I can pack and unpack with WinZip, encrypt it, etc. with other tools and the timestamp not change (again, for EXEs). It makes no sense for avast to change the stamp.
Thanks for the reminder about the Folder stamping - I had forgotten about that.
With regard to reporting psexec - it is already known. It's a tool from Sysinternals (now owned by Microsoft) that's in a suite of tools hackers also use in their viruses. avast should be flagging it. It's similar to VNC - it should be flagged, but it's honestly a false positive in most environments (since "false positives" are relative to an environment anyway) that should be easier to exclude than avast provides means to do.
With regard to the exclusions and the chest's operations, that's really pathetic. This is one of the most basic functions of every other antivirus software I've used (Trend, Symantec, Kapersky, etc.). I'm pretty impressed with avast overall, but there are a few things they just seemed to have completely missed the mark on.
Also, I do appreciate the potential workaround suggested with regard to placing these files in a single folder, but it isn't realistic at all. One should not have to reorganize one's directory and file structure to accomodate a poorly written design. So, I'll go with another product on these workstations and use avast on the others.
Thanks again.
