It could be the Trojan that's causing the problem with WR having read this manual removal article.
http://blog.mitechmate.com/trojandosalureon-j-virus-removal/Given that it can open up your computer to other nasties, do not use your computer for sensitive operations such as banking or even your email until it has been removed.
As the removal steps involve deleting registry items, create a system image onto DVDs - while it would be an infected image, it would still give you a fall back should removing the wrong items cause problems and when you've gotten rid of it, you can dump the DVDs and create a fresh new image.
If you want to try another Rootkit scanner before going the registry route etc. then you could try Norton Power Eraser.

Ever since I got my first laptop in 2010 I have been using Norton.
First with Norton 360 and now with Norton Security Deluxe (without Cloud) which has superseded 360 and that has kept me safe.
However, no AV program is 100% effective, it's just that some are more effective than others.
Norton 360 wasn't without its problems as after any Windows Updates, I had to do a manual check for its Definitions before it would let me open IE, but Norton Security doesn't seem to have that problem, although both it and 360 have blocked downloading AdwCleaner from
http://www.bleepingcomputer.com/download/adwcleaner/ which I occasionally run a scan with.
Kaspersky seems to be at the top of the heap in paid for AV program reviews at the moment and is cheaper than Norton, but the free Panda Cloud has come up through the ranks of late - have a Google for best free AV programs.
However, there's no defence against a user clicking on the wrong links except a system image, which is also the only defence to combat Ransomware.
