AntiPascal Family
Description AntiPascal Family
These are dangerous not memory resident parasitic viruses that contaminate or corrupt not more than two files in all directories on the current disk and C: disk. Searching for noninfected files, the viruses use recursive traversal of the directory tree. They contaminate .COM-, .BAK- and .PAS-files. In case of .COM-file, the viruses write themselves at the end of a file (versions of the viruses with lengths 400, 407, 440 and 480) or at the beginning (all other versions of the viruses). When infecting .BAK and .PAS-files the viruses write themselves at the beginning of a file, not saving the old beginning, i.e. the file is damaged irreversibly. Some of the virus versions rename .BAK- and .PAS-files to .EXE.
"AntiPascal.407" deletes *.?A? and *.SYS files, it contains the internal string: "COSMIC-1".
