I have been using an application "SWiSHstudio" by www.swishzone.com, to make Executables.

"upx.exe" has been used in it for some time for 'compression'.

Today when I export an EXE, ZoneAlarm-Pro reports/alerts/warns
"upx.exe has been blocked from creating a new process"

Apparently ZoneAlarm just implemented/picked-up "upx.exe" in most recent update
(less than 24 hours old)
because yesterday "upx.exe" did not trigger an Alert/Warning.

The "more info - details" of ZoneAlarm did not produce enough satisfactory about IMHO.

Did my usual "Google" on-for 'upx.exe' and found listing here (BleepingComputer.com).
Bleeping Computer - upx.exe - File Information

Does anyone here have experience and/or exact information about "upx.exe" what it does to make it malware when NOT "Added by a variant of the AGENT.AH TROJAN!"??

Occasionally malware and legitimate files end up with the same filenames. UPX.exe is a variant of the WIN32.AGENT.AH TROJAN only if it identifies itself as 'notepade.exe'. See http://castlecops.com/s6693-upx_exe.html .

For piece of mind, try uploading the version of upx.exe you have to the Jotti's malware scan site and see what it has to say.
