KMIT virus installs itself to high DOS memory, decreasing available memory by 8336 bytes. It hooks interrupts 09h (keyboard), 1Ch (timer) and 21h (DOS).
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.
Once the KMIT virus is memory resident, it will infect executed COM and EXE files. File length increase will not be visible as long as the virus is resident. The virus code is located at the beginning of COM programs and at the end of EXE programs.
KMIT will corrupt COMMAND.COM if it infects it. This will result in a continuous series of reboots occurring when the machine is booted up next time.
