A few days back i tried downloading something from a random torrent, my browser got changed into a russian website, i changed it and no problem occured, then after 10 minutes a pop-up started appearing on my screen every 20-30 minutes or so , it says '' how do you want to open this file'' , when i try to open it with the notepad it says that ''Program.txt was not found , want to create another notepad'' or something similar, i really need help on removing this virus(i think) as fast as possible!
