I have a program trying to flash on my screen. It is every 12-15 seconds apart and only flashes for a half second. I have tried to click on it. I have disconnected from the internet as I thought maybe someone was trying to access my computer. Still does it. I ran3 different spyware and antivirus programs. Plus, I ran rkill (all 4 types). I still have the problem. If I am typing while it flashes, it erases my typing. I have defragged, debugged in addition to running spyware and antivirus programs. After doing each one of them, I have restarted my computer. Still get that flash. It is driving me bonkers. Hope someone can help. thanks, Lloyd
