Vius on my Amiga 500

[Piru]

I have additionally an 512kb Ram Extantion, could it be that the virus is copied to other disks via this?

No.

However, most of the bootblock viruses are memory resident and stay in memory if you reboot with CTRL-Amiga-Amiga. To really get rid of the virus in memory you need to power off for 30 seconds.

If your A500 has Kickstart 1.3, use: VT-Schutz

Use DMS to extract the .dms to a floppy disk, available here: dms111.run

If your A500 has Kickstart 2.0 or later, I recommend VirusZ.
