Uninstall any Bittorrent apps, uninstall cracked programs and delete cracks then Post in only 1 forum, then wait. Please let us know if this solved your issue or if need further assistance.

Thanks Pkshadow it did not and i only installed BitTorrent recently, does it mean that vfirefox.exe is not from firefox

Is very possible. Have seen yes, and have seen no and this is the 1st time I have heard of it so would say no is not part of..

If downloaded any programs or games I would think you have problems. Uninstall what ever you installed. Run Malwarebytes and if it gets cleaned great if not then you must uninstall all that I have said or they will not help you.

If know how to Right Click copy link Location then something like bitport.io is very good. Stay away from programs and games.
