I just recently installed the Windows 8.1 update earlier today. Immediately after the required restart, my computer has not been working properly. As soon as I log on, the desktop flashes back and forth from the desktop picture to the color of the menu background. It flashes back and forth pretty quickly and while this is happeneing I can't perform any functions. When I try clicking on the internet or anything else it is nonresponsive. I tried doing a system restore but after my computer restarted it said the restore was unsuccessful. I tried it again, as well as trying it from a different restore point but neither would work. I then attempted to restart my computer in safe mode but immediately got a pop up saying: "The instruction at 0x35f7649c referenced memory at 0x35f7649c. The memory could not be rewritten. Click OK to terminate the program." After clicking OK, the popup immediately came back and neither clicking OK or pressing the X in the upper right would make it go away and it would just immediatley pop back up and I could not click on anything else while it was up. Also while in safe mode, my desktop shortcuts and desktop picture were again flashing. I'm concerned I have a virus but not exactly sure how I got it or how to fix it. I have Webroot installed and it alerted me to a potential virus a couple days ago but when I tried to fix it, it said something about my product key expiring it and since it wasn't causing my any problems I ignored it. I also have McAfee, but it has not alerted me to anything. At this point, I am not confident I could even access my antivirus to fix the problem. Any suggestions would be greatly appreciated. Thank you!
