That's odd. I downloaded and installed the 32 bit version as described above on May 28th. At the end of the installation process my antiviris software raised the alarm. It's Avira Antivirus. I now found a log file holding this information:
- [INFO] RepairMalware: Remediation of malware TR/Crypt.XPACK.Gen needs a reboot to complete
Today I took the very same DVDFab installation file which raised the alarm on May 28th and installed that program again. Now the antivirus software stayed silent. But this software seems to get an update very often. Maybe there was a glitch in the antivirus version on May 28th and that was changed with one of the 40 updates this software received since May 28th.
