USSR 1014 Virus

Virus Name: USSR 1014 Aliases: 1014 V Status: Rare Discovered: August, 1992 Symptoms: .COM & .EXE growth; decrease in total system & available free memory Origin: USSR Eff Length: 1,014 - 1,028 Bytes Type Code: PRhA - Parasitic Resident .COM & .EXE Infector Detection Method: Sweep, F-Prot, IBMAV, VAlert, ViruScan, AVTK, NAV, NAVDX, PCScan, ChAV, IBMAV/N, Sweep/N, Innoc, NAV/N, AVTK/N, NProt, LProt, NShld Removal Instructions: Delete infected files General Comments: The USSR 1014, or 1014, virus was submitted in August, 1992. It is originally from the USSR. USSR 1014 is a memory resident infector of .COM and .EXE programs, including COMMAND.COM. It does not infect programs smaller than approximately 16K. The first time a program infected with the USSR 1014 virus is executed, this virus will install itself memory resident at the top of system memory but below the 640K DOS boundary. Total system and available free memory, as indicated by the DOS CHKDSK program, will have decreased by 1,040 bytes. Interrupts 10, 21, and 60 will be hooked by USSR 1014. Once memory resident, the USSR 1014 virus will infect .COM and .EXE programs when they are executed. Infected programs will have a file length increase of 1,014 to 1,028 bytes with the virus being located at the end of the file. The program's date and time in the DOS disk directory listing will not be altered. No text strings are visible within the viral code. The USSR 1014 virus will also alter .COM programs smaller than 16K in size, adding 2 to 30 bytes to the file. These files are not infected, and will continue to function properly.
