My computer has started doing this weird blanking-out thing where sections of text disappear, not just from pages I view, but from the windows themselves. After it does this, I can click things and the cursor will change, but nothing changes on the screen. If I hit CTRL-ALT-DEL and open the task manager, the TM window never shows up. It won't even let me shut down the computer. The only thing I can do to stop it is to manually turn off the computer. Once I turn it back on, the computer is normal until it goes blank again.
I'm not sure if this is related, but whenever I search for something on Google, the first result I click (even if it's not the first result on the page) will bring up a window with a redirecting site. However, if I close that window and click the same result again, it lets me go to the right page.
I don't know if these issues are caused by some kind of memory problem or some form of malware, but the blanking out thing comes and goes. I'm not sure if it's caused by the computer being on too long or by me using a specific program that triggers it (the only ones I've used lately are MS Word, Internet Explorer, MS Paint, Avast, MBA-M, and spider solitaire). The only recent change in the computer is that we changed our internet service from high-speed to DSL.
Here is my most recent MBA-M log:

The DDS scan ran, but never gave me a log file, even though I ran it two or three times. Sorry about that.
