I dont know what your talking about here. But there is a Amiga virus named as Ebola. Once its installed, its pretty hard to get ridd off.
I never had Saddam or CCCP etc. Had Byte Bandit and Lamer Exterminator sometimes, but there is a virus called Ebola which is mystic. I dont know what it does, but it messes up with the startup-sequence and uses up lots of mem.
I formated my HD on my A1200 many times to get ridd of it. Virus checked all of my disks etc.
When Ebola was attacking, ViruZ or VirusChecker found it and killed it. After some time, it appeared again.
I found the virus on my Dpaint 5 disks mostly. Ebola dosent harm other than AmigaOS feels very slow and different.
Maybe your talking about Ebola?
