Just downloaded Build 2430 from Cyberlink website as per customer service instruction filename: PDVD8_2430U_DVD081202-02.exe. Then right after download, I manually scan the downloaded files with BitDefender Internet Security 2009,
Found Packer.RLPAck.D virus in Data1.cab included in the installation archive.
And after extraction, these files are: ddabc.dll, ddabcd.dll, ddorz.dll, ddorzd.dll in \VideoFilter folder under c:\Program Files\Cyberlink\PowerDVD8.
These filese were found in both build 2430 and 2521!!!
SO I proceed to install build 2521, then remover these 4 quarantined virus files in BirDefender, PowerDVD8 Ultra start and run fine.
These 4 files may be unnecessary and come from Cyberlink's infected PC? I never seen these files in build 2217a and before.
