My computer keeps getting pop-ups. Everywhere. Sometimes at least 5 pop up at a time. My AVG Anti-Spyware (by the way--is that a good/bad program?) found something called wauaboot.exe and cleaned and moved it to quarantine. There's a whole bunch of them in there now...and it's all like the same thing. AVG says it's infected with Adware.PurityScan. It's under the file C:\WINDOWS\system 32\AppPatch\wuauboot.exe What to do? Please, I need to fix this very soon.
