Hi there

Please download this,this usually will delete all unwanted trojans etc 

First program which I would try is Malwarebytes Anti-Malware and then I would go down the route of the Adwcleaner and Combofix,for bellow programs here are links

Usually those programs will delete anything what is unwanted or what is dangerous

Yes this happens to my brother with his laptop,when he tried to download Adobe flash

Not sue I've recovered all my files from crashed HDD and too from HDD which has been full of viruses with above programs,but be 100% sure I would go down the route of the Safe boot and then I would try to recover files 

This virus looks like is it Ransonware which are worst,does this virus started to lock yours folders or not? If yes then I would suspect you have one of the worst virus which is called Cyberlocker,but I think someone has cracked their code which is good news 

Hope this help

Thanks,Jura
