Qrry

Threat description

Details

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.
