Virus on my Amiga Disks

[Andrew]

Hi there

A few years ago I bought a game from ebay and it turned out it had a virus on it and infected a lot of my disks. I thought i managed to get rid of this virus but there must have been 1 disk that escaped when i used my virus software on it.

The problem with the virus is that when you load workbench and the anti-virus sofware, it infects the wokbench disk and any other disks you put in DF1 while the infected disk is in DF0. To run the anti-virus software, you HAVE to have workbench in, so therefore gets infected.

I can't get the program I originally used to clean my disks to work, in don't know why, though. I was wondering if there is a bootable from disk anti-virus programm out there i can use to clean my disks. Many thanks for any help given, i hope i have explained it well enough.

Thanks

Try having a look on here. Some bootable floppy disks available:

what you do is boot from a write-protected floppy with the virus killer on it. Do you remember the name of the program? I may have it somewhere....

Hi there. Thanks for your help

The program i used originally was called simpley Virus Checker i think. It was put on the Amiga Shopper coverdisks very regulary as new updates came out.

I think all my Amiga Shopper coverdisks are infected I think. Your right about copy-protecting the disks. The virus is spread by using the infected disks with clean ones eg. Infected disk in DF0, put a clean one in DF1 and acess it, and it will become infected.

Oh yes, the great days of old when stopping viruses spreading was as simple as flicking a little plastic switch.

Actually this method can still be used today if you have a Windows XP machine - it's that good I'm suprised that nobody has mentioned it before....who needs Norton Aunty Virus/SystemOverload 2012 when you can use this method, and the best thing is it's free !!


.... still here? .....


.... OK.....



Jim's Top Anti-Virus Tip

Just reach around the back of your computer, you should see a black plastic switch quite larger than the ones you get on floppies. Rather than try and slide it simply press it - that's it, no more viruses - your machine is protected

hmm i'm guessing your workbench disk is infected. okay what you can do is this.

do you have 2 drives if so, slap workbench in df1: and another AmigaDOS disk in df0:

boot up amiga dos, press ctrl-c/d, untill it says **break**

then put in disk with virus killer in df0:.

then do df1:c/dir df0:

you may have to use df1:c/cd df0:directory_that_has_virus_killer_in_it.
then df0:viruskiller

and hope like hell that the virus killer doesn't require libs that are in df0:libs...

Hi Andrew

I have just uploaded two DMS files to the Zone for you. Both are from the 17 Bit PD Library CD Rom (CD#5). If they don't cure your problem let me know and I'll grab something else for ya from Aminet. Do you need the DMS extraction util etc??

[Bloodwych]

Great of you of to help him lloyd, but didn't Andrew find the DMS files on that link I posted above - they are fairly up-to-date.

Download Packed Boot-Able floppy-disk's.
If your system is infected with a virus, this is the safest way to test for virus, just unpack the .DMS archive to a floppy, and boot with the disk

[lloyd]

Ah!!

ermmmmm I didn't see the link

I just made a point of remembering to send him some stuff (which was before your post) and when I finally got around to it, you'd already posted him a link - so doh!!! to me for not looking and thanks to you for supplying something else more up to date. He did say it was an old virus he had tho....

[Bloodwych]

Hey no problem lloyd - like I said it's great you're offering help!

Just wanted to point out the DMS files from that link again as he may have missed them.

You could also try to find a disk with System-Z/Pvl AV on it...Best Anti-Virus I know....It will stay resident in memory and if you overwrite a Bootblock it will copy itself on the disk giving you more protection...
There is no need to worry about damaging healthy disks and people who claim it is a virus are not credible IMO...Hope it helps

HUH?
That's barely logical!
It *cannot* infect your Workbench disk if you write protect it!
If you really *require* to have your WB write-enabled (probably because of "Command-0-T01" in T: ), then your startup-sequence should get an overhaul on the double!
