False positive report in VMware Thinapp 4.5 packed executables

I report a new false positive alarm by avast 5.0 home free (Win32:Trojan-gen) for all executables packed with the new VMware thinapp 4.5.
No false positive signal was reported until Thinapp 4.0.4 packed executables.

Avast 5.0.462 free ITA
signature file version: 100321-0

Thanks

Please pack a few of those executables into a password protected archive (ZIP, RAR, 7-Zip) and send them to virus@avast.com (together with the password), with a False alarm subject.
Thanks.

Hello,
thank you for sending sample. False positive will be fixed in next VPS update.
