Hi there, I have a virus (or malware, trojan, etc.) that is not only sucking on my PC's performance, but affects all input too. When I try to type something, I click on a field to enter the data, but the active cursor jumps to the address bar, accepts only one key stroke, and begins blinking like crazy as if I were typing a million key strokes and over-loading it. Sometimes a yellow bar also appears below the address bar that says, "Skip to main content." The only way to stop it is to hit the ESC key. This affects all data entry, including in Word and other Office programs. Also, video is affected. When I'm watching a YouTube clip in full-screen, it suddenly reverts to the smaller screen and freezes until I hit escape - but the audio still strangely plays. It has also crashed a few times while watching video. I re-formatted, but the problems came back, which leads me to believe that the virus/whatever is attached to one or more of my personal files. It was a pretty strong PC when I bought it last year (quad core 3.4ghz, 16gb memory, 2gb video), so the drag on performance is pretty shocking. I ran a Windows Security Essentials scan, CCleaner, ESET, TDSS Killer, and all of them show zero issues - but nothing like this was happening before August. I also tried uninstalling my video and keyboard drivers, but that didn't make a difference. Any help would be HUGELY appreciated, as I can't stand my PC acting up like this!! Thanks very much!
