So a friend in the next town calls last evening because he has a trojan that is demanding his credit card numbers. Not sure if it was a fake A-V or just something similar but after XP would load it wouldn't let him do anything else. So I search out how to install Malwarebytes on a thumb drive but my initial results were bringing up threads from 2009/10 and some of them were saying you couldn't do that. So then I searched rescue CDs and read ComboFix and some other reviews and was spooked off with caveats about analyzing what you remove. I knew most of the A-Vs now have rescue CDs so I chose K first and find a review that originally claimed they didn't keep it updated but the reviewer had that crossed out and had added that they really stay on top of it now. I search further and find a thread "K 2010 rescue update 6/9/2012" or something like that. So it being just two days old I download/burn it and head to my friends home. Now in one of the threads it stated that it would open in a Linux environment and at another site it did show two different downloads (back to this point later). So we attempt to boot from the DVD (that is all I had) three, four, maybe more times and all that ever happens is it shows like 20/30 file types then loads Windows, so we are thinking his DVD player isn't working. Long story long it turns out the virus was gone. So two questions: Is this how it is supposed to work, just quickly showing the files it has cleaned? Are there two different downloads, the Linux one for a system that won't even boot? Thank you for reading the long epic! edit: and yes, I had changed the BIOS setting to boot from CD/DVD!
