Int10 is an unusual boot sector virus. It infects MBRs on hard drives and floppy boot sectors.
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.
When an infected machine is booted from the hard drive, Int10 removes itself temporarily from the MBR and INT 13h chain in order to hide it's presence. When DOS has been loaded, it reinfects the MBR.
Int10 does not appear to be deliberately malicious. It activates at midnights during December or six hours after the machine has been booted (again, only in December). At this time it displays a graphic snowfall on-screen and halts the machine.
Int10 is encrypted with a simple key.
There are three known variants of this virus.
