how do I get rid of the "Ebola" virus?

Possible symptoms:
executable file size grows by 1116 bytes after run.

Possible reasons:
- system infected with Ebola virus

Possible solutions:
- remove Ebola virus:

1. get antivirus software (e.g. VirusZ or VirusExecutor) from http://www.vht-dk.dk/ or from AmiNet: http://aminet.net/search?query=virus
2. put antivirus on some media that can be mounted from shell
3. have a write-protected, virus-free workbench bootdisk*
4. boot from write-protected, virus-free workbench bootdisk, mount media with antivirus software as required
5. run antivirus software, scan all drives / files, hit "repair file" or "remove virus" as indicated by antivirus software ("Ebola" can be removed successfully. May fail on OS3.9 "SetPatch", though. Replace bad file with good one from original installation media, if required.)
6. run HDToolbox, check every partition of harddisc for RDB's installed filesystem: go to "Advanced options..." -> "Filesystem..." -> "Change/Update..." and compare size of installed filesystem with filesystem on disk (now scanned/cleaned). Re-Install filesystem from disk, if it's 1116 bytes smaller than the one installed in RDB. (Keep in mind AmigaOS versions: compare filesystems of equal versions.)
7. switch off Amiga and let rest for at least 30 seconds

*) not strictly required, but may avoid multiple de-contamination runs/reboots
