F-Secure Virus Descriptions : Halloechen

                     Hall"chen !!!!!!, Here I'm..

                         Acrivate Level 1..

This virus is a bit unusual in some ways - for example it will not infect "old" files. If the value of the "month" or "year" fields in the timestamp is different from the current date, the file will not be infected.

The virus does not modify the creation date when it infects the virus, and like most other viruses it is easily able to defeat the read-only attribute. It will only infect files larger than 5000 bytes.

The major effect is reported to be garbling of keyboard input.
