CheckX detects all the viruses found by xvs.library, which contains the complete antivirus knowledge of VirusZ utility by Georg Wittmann, Alex van Niel and Jan Erik Olausen. CheckX can NOT remove detected viruses. You still need antivirus software like VirusZ, VirusExecutor, VT, Mill or VirusChecker.

I always run VirusZ in the background to check for viruses. CheckX also scans disk archive information texts for packers and viruses, bootsectors of dearchived disks and is able to scan for destroyed sectors. The memory is scanned once after starting CheckX.

This program uses xfdmaster.library and xvs.library for packer and virus scanning. The xadmaster.library is used to dearchive file and disk archives.

The complete number of found viruses is logged at the file end, if the scan found some of them. Also the scan time and the number of errors (if some appeared) is logged.
