1210 VIRUS

The 1210 Virus (Prudents Virus) is a memory-resident computer virus which infects .EXE files, increasing their size by 1210 bytes, when they are executed. The virus is loaded into memory by executing an infected program and then affects the computer's runtime operation and corrupts program files. The payload activates at the beginning of May, changing all disk writes to disk verifies, thereby preventing data being written to the disk.

123NHALF VIRUS

The 123nhalf virus was so named because it causes a Lotus 1-2-3 release 3 spreadsheet files to be saved exactly one half the size they should be. For example, a 100 x 100 cell spreadsheet will only be saved as a 50 x 50 cell spreadsheet. The virus only infects the file 123DOS.EXE, and the file grows in size by 3907 bytes. Any spreadsheet saved after the virus has infected the file is exactly half the size of what it should be. If the 123DOS.EXE file is erased and restored from a backup, and 1-2-3 is run again, the file again grows in size. The virus only infects the 123DOS.EXE file, when running on a machine with a 80286 processor. it will not infect the file on a 80386 system. The virus also will not infect files unless there is a minimum of 3 megabytes of extended memory.
