A new flaw was found in Trend Micro's virus - scanning software. Exploting a security hold in the program's Antivirus Library, the program would execute the virus instead of blocking it.
The other products from Trend Micro also affected are Trend Micro Interscan, Trend Micro ScanMail and Trend Micro ServerProtect.
An advisory released states that customers should update their Antivirus software to version 7.510 to fix the problem. Source
