Hello there,
Earlier today, I tried to download a survival addon fix for my Call Of Duty: Modern Warfare 3 Black Box. After I installed the program, my laptop started going ballistic: Unknown programs installed (UC Browser, etc) and my chrome startup page changed into yeadesktop.com (Not to mention that the app, Yeadesktop was also installed for a brief amount of time.). I tried running all of the security programs that I had and also uninstalling and deleting all of the unknown programs alongside the related files, but nothing happened. At this time, the command prompt started flashing. Not just one, but four. The cmd.exe that pops up is blank and pops up diagonally for approx. 1 second one by one. Also tried running Kaspersky's TDSS Killer, but it doesn't work, says my laptop's clean and I still have the flashes.
I tried googling for answers, but gave up when I can't find a fix. I tried restarting the laptop for 3 times, if I'm not mistaken, but the flashing becomes worse. The cmd.exe that flashed doubled in number and flashed even more faster than before (The flashing pattern is restarted, so after the first 4 cmd.exe finished flashing in a diagonal pattern, the second 4 follows at the same spot where the first 4 flashed). When I'm writing this, I'm still having the cmd.exe flashing for every few seconds (20 seconds max with no flash). I tried to play some games, but they're interrupted by the flashing cmd.exe.
