On the rare occasions when something like this has happened, I’ve just used the system restore feature and it worked like a charm.
Just got hit with this little b@stard two days ago after visiting the Pravda site after jumping over from the Drudge Report. Googled and found a lot of activity on this bugger. Went to the malwarebytes.com site and downloaded the free cleaner. It worked perfectly
The bugger disabled my system restore feature.
