This is not a virus, but a common false alarm from CPAV (Central Point Antivirus). The following text is from "Frequently Answered Questions Document for Central Point AntiVirus and Microsoft Anti-Virus. FAQ Version 2.0":
3.b VSafe says the Teletype virus is present on a floppy disk. The Teletype virus is a false positive virus alarm. The Teletype virus does not exist. The floppy disk needs to be reformatted with a later version of Dos than is on it now. The only time this message will appear is when a floppy disk was formatted with a very early version of Dos is accessed while VSafe is loaded. Simply copy the files on the floppy disk to a directory on the hard drive and type FORMAT A: or B: and press [Enter]. After the format is done copy the files back to the floppy disk.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
