AntiExe is a simple boot sector virus, infecting floppy boot records and hard disk master boot records. The virus is very small and it is not encrypted.
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.
AntiEXE uses stealth techniques, so infected boot sectors look clean if inspected while the virus is resident. F-Secure anti-virus products will detect if AntiExe is resident, and will advise you to boot from a clean diskette.
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-write-protected floppies used in the machine will be infected.
AntiExe virus redirects the BIOS disk interrupt 13h to unused interrupt D3h - this way the virus can bypass some behaviour blocker programs.
AntiEXE targets an unknown EXE file, sized 200768 bytes (memory size 200256 bytes). Whenever this specific EXE file is accessed, the virus prevents it from running.
AntiExe is very common all over the world.
