Explosion

This is a 1000 bytes long, parasitic and resident virus attacking COM and EXE files. On the seventh day of each month, if also other conditions of installation are met, the virus announces the following message:

Dis is one virus. Leave the room IMMEDIATLY !!! Your PC is about to EXPLODE within 20 sec !

Below this text a countdown follows accompanied by beeping sounds. When the countdown comes to 00, the virus writes:

EXPLOSION
What did you expect ?

And nothing more happens. It is not true that this virus destroys files and blows computers in the air. The problem is that it differentiates between COM and EXE files only by their extension and that is not sufficient. By this activity the virus puts some non-standard programs out of action (e.g. several DOS programs). It causes problems with Windows in the net. This is the first virus of the line of development consisting of viruses Explosion, One_Half and EMM:Level_3 by the author “Vývojár”.
