I was watching a show on netflix today when suddenly my browser closes and I get a message popping up that I have viruses on my computer and to 'buy now' to get rid of them. After confirming on google that Win 7 2012 Security is a virus, I reboot into safe mode and use my copy of malware bytes to scan and rid myself of the files. Because this has happened to me far too often I also ran trojankiller, rkill, and TDSS killer. So the virus is gone, no more popups, but I have no more internet connectivity! I've restarted my computer and my router/modem and I'm fairly sure the problem isn't in my browser; my wifi connectivity monitor in the taskbar shows I'm connected with no internet access. I initially thought it was something wrong with my hosts file, since something similar happened when I had AV security 2012 virus on my computer, but I *successfully?* renewed my hosts file and after a reboot still no internet.

I'm running Windows 7 Home Premium 64 bit OS Intel core i5 2410M CPU 2.30GHz with 8 GB ram. Any takers?

Please download Farbar Service Scanner

http://download.bleepingcomputer.com/farbar/FSS.exe

and run it on the computer with the issue.


* Press "Scan".
* It will create a log (FSS.txt) in the same directory the tool is run.
* Please copy and paste the log to your reply.
