Threat Description



Aliases: Cleaner
Category: Malware
Type: Virus
Platform: W32


Cleaner is a simple memoryresident virus which infects COM and EXE files when they are executed.

Cleaner activates on the 8th of September on every year. At this date, the virus will display the following text on the screen:

     O     HDD-CLEANER  Version 2.0      O         O   Copyright (c) 1997 (1st JAN)    O         O      Made in Hungary, Sopron      O        DESTRUCTION IN PROGRESS...  

After this the virus overwrites the beginning of the hard drive. Only the first 16 sectors are overwritten, so recovery is possible.

Cleaner will also cause different compatibility problems. It was found in the wild in June 1997, after the Hungarian Magazine CHIP accidentally distributed it on their cover CD-ROM.
