So I got this new MacBook Pro from work.
Yesterday I was trying to find a registration key for Quicktime Pro on the Internets and having a hell of a time. So, on my Vista PC, I googled “quicktime pro registration keygen” hoping to find something worthwhile. First hit looked promising so I clicked. Looked like a self-extracting RAR file. I felt lucky so I opened it. There were three .exe files, all under 10k, and they all launched in separate DOS windows, closing just about immediately.
Shit.
Shortly thereafter the computer rebooted. Blue screen, reboot. I tried Safe Mode. Blue screen, reboot. I tried all the other standard F8 options. I couldn’t shake the blue screen. One option I did try was to prevent the PC rebooting on a blue screen, hoping to find the culprit. There it was: lzh32.sys
Luckily I was able to do a system restore from the Vista DVD. I never had any faith in this MS system restore stuff until now.
Moral of the story: Do never open self-extracting RAR .exe files. Open them in WinRAR first.
