Notes about the VIRUS file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The VIRUS file type is primarily associated with 'F-Secure' by F-Secure. The F-Secure rescue CD will scan all connected disks and rename any suspected infected files with a .VIRUS file extension.
