This is a simple virus, which will infect one .COM file when an infected program is run. The virus may emulate a parity error, displaying
PARITY CHECK 2

Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
