Summary
The Qrry virus is a reasonably simple diskette and Master Boot Record infector. It is only able to infect a hard disk when you try to boot the machine from an infected diskette. At this time Qrry infects the Main Boot Record, and after that it will go resident to high DOS memory during every boot-up from the hard disk.
Once Qrry gets resident to memory, it will infect practicly all non-writeprotected diskettes used in the machine.
Qrry contains the text 'QRry'. It doesn't recognize 1.44MB HD correctly, and overwrites one sector in the middle of the data area. This area is cylinder 39, Side 1, Sector 9.
Qrry activates in December, when it overwrites part of the hard disk.
Removal
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.
