several of us, including me- TWICE- have contracted this really shitty piece of malware.
here is what it does:
when you are on some website (could be almost any, ime- but i got mine once at youtube, or some site linked from youtube), you will suddenly get a popup for antispyware. it will inform you that you have an invasion, and that you need to download their software to fix it. if you try to close the program, it won't let you. it will remain resident on the screen, or it will pop up any time you try to run a program.
what this malware does is rewrite your .exe associations in your registry, and block all access to the internet. so if you try to download software, or find a fix for it, you can't. it only takes a few seconds to screw up your registry, so there is really no time to fix it before it gets you.
here is the procedure for fixing it:
1) do a hard shutdown on your computer by "powering down"
2) start back up in "safe mode"
3) create a NEW USER (this is something you can do in safe mode) with admin functionality
3) "log off" and when you come back up, access the new user.
now you will have a registry that does NOT have the bad .exe association.
you can access the internet and download the trial version (free) of MalwareBytes.
run a full scan and delete the malware.
now, go on the internet to HERE:
http://www.sevenforums.co...ssociations-restore.htmland download the registry patch (the one labeled EXE). here is where it gets tricky. since you have to run the patch from the defective user area, and you can't do it because it limits access to the net, you have to open the NEW user first, get the patch, and right click and download it to the C: directory (which is accessed through My Computer). once on the root directory, you can use the "My Computer" method to find the patch and run it from the defective user. you don't need to reboot, it fixes the .exe association immediately.
