• Scans archive files with file name extensions: ARC, ARJ, CAB, LZH,

RAR, TAR, ZIP, and their contents, if you are running Windows NT or

Windows 2000.

virus definition (.DAT) files classify as susceptible to infection.

• Cleans infected files immediately upon access or when saved.

• Records its activities in a log file.
