I'm embarrassed to admit it but I've fallen victim to the jzip/searchqu curse that's nailed so many others. I've looked at some of the previous threads for this but don't want to follow the exact instructions because they might be tailored to that user's computer, based on their logs. But, I have downloaded OTL, so I have that ready, if needed.
I'm a bit of a PC noob, so any help is definitely appreciated. I'm running Win7 Ultimate.
