This is a harmless memory resident parasitic polymorphic virus. It hooks INT 21h and writes itself to the end of COM and EXE files that are executed. It contains the text strings:
I'am SLOVAKIA virus Version 1.2 Copyright (c) 1994 SVL
chklist.ms chklist.cps smartchk.cps svl.svl
.exe .com
scan avg vir asta alik rex msav cpav nod clean
f-pro tbav tbuti avast nav vshie dizz vsafe
It displays the first (and second) strings, deletes the files from third (second) string. The fourth (third) string contains the file name which is used on infection (the virus renames the file into that name on infection and then renames back). The next string contains the file names which are not infected by this virus.
