Geodesic 2.0 Virus

Virus Name: Geodesic 2.0 Aliases: V Status: Rare Discovered: February, 1994 Symptoms: .COM & .EXE growth; file date/time seconds changed to 8:58:08a Origin: New Eff Length: 666 Bytes Type Code: PRhAK - Parasitic Resident .COM & .EXE Infector Detection Method: AVTK, ViruScan, Sweep, F-Prot, ChAV, NAVDX, VAlert, NAV, PCScan, AVTK/N, Sweep/N, NShld, NAV/N, Innoc Removal Instructions: Delete infected files General Comments: The Geodesic 2.0 virus was submitted in February, 1994. Its origin or point of isolation is unknown. This virus is a memory resident infector of .COM and .EXE programs, including COMMAND.COM. When the first Geodesic 2.0 infected program is executed, this virus will install itself memory resident at the top of system memory but below the 640K DOS boundary, not moving interrupt 12's return. Total system and available free memory, as indicated by the DOS CHKDSK program, will have decreased by 1,632 bytes. Interrupt 21 will be hooked by the virus in memory. Once memory resident, the Geodesic 2.0 virus will infect .COM and .EXE programs when they are executed. Infected programs will have a file length increase of 666 bytes with the virus being located at the end of the file. The file's date in the DOS disk directory listing will not be altered, but the file's timestamp will have been updated to 8:58:08a.
