We interrupt our regularly scheduled npr and paleo posts to say… say no to scareware. I spent all day cleaning and rebuilding my system, and would have spent more if not for the fantastic aid of Daniel Koenig, from CAI Systems. As these things tend to come in waves, I thought I’d share the solution and spread the word.

The thing that shocked me about this is that I have a decent level of protection (with AntiVir business edition) and wasn’t on any dubious sharing sites or such. Nor did I click any buttons, attachments or similar. And still I got this nasty system warping… thing. It bars access to all system controls such as the task manager and reports disk errors in a visually convincing Windows panel. (I was put off about a supposedly missing c disk despite having already booted.) Anyway, turning off the autorun options is the way to stop this kind of stuff, and I’m apalled at how deeply buried this option is in Win7. Daniel to the rescue… he found it.
1) enter gpedit.msc in the search bar of your start bar (it will only appear after being entered in full)
2) navigate to the user and computer configurations (successively) / administrative templates / windows components / autoplay policies. For you Germans out there, the panel is called “Richtlinien fuer automatische Wiedergabe”
3) enable “turn off autoplay”, “turn off autoplay for non-volume devices” and “default behavior for autorun” paying attention to the details they offer about each option.
How’s that for convoluted?
