W-boot is a stealth boot sector virus that infects MBRs on hard drives and floppy boot sectors. It allocates 1kB of memory.
The virus will only infect hard drives when an attempt to boot from an infected diskette is made. Once the virus has infected the hard drive, all non-protected floppies used in the machine will be infected.
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.
W-boot uses stealth routines, so it cannot be found from boot sectors when it is active in memory. F-Secure anti-virus products detect if W-boot is resident, and will advise you to boot from a clean diskette.
W-boot contains no texts and has no activation routines.
Some programs also detect the W-boot virus as EXEBUG, but this virus is not related to ExeBug at all.
There are three known variants of this virus. W-Boot was known to be in the wild in Luxembourg in April 1995.
