Got an instant hit by the DOJ ransomware stating my computer is locked until I go to CVS and pay $300. Also; something to do with child porn...
I immediately restarted in the safe mode and ran a full Avast virus scan with no indications of a bug.
Returning to the regular boot-up, I attempted to get online again. Firefox 23, Win7 32bit. Same problem.
Thinking only the browser was affected, I uninstalled FF.
I'm using the Avast safe browser now.
When I attempt to re-install FF I get "XPCOM not found". I believe this is a DLL.
Right now I'm using the laptop (affected machine) and have a desktop at home to get any necessary downloads. It seems anything I attempt to download in this browser stays in it, and I am unable to access the download when the browser is closed.
Any suggestions?
Also, Avast AV never even noticed all that was going on!?
