Font resizing and those damn popup ads

[Kikinchikin]

In the past 2 weeks, I've started to notice I've been getting a heavier amount of popups (often knocking me off FFXI and lagging my computer to shit and back). Then a few days ago, I logged on to suddenly notice that many fonts on websites (such as the font in peoples' sigs and the quote font) were very very small. I think that a popup made them this way. Then just now, those same fonts became very big. It's one of those nagging things that piss me off, so would any of you all know how to fix it? Also are there any popup blockers that actually WORK that I could download for free? Or even buy? I'm so pissed off at these damn popups, I want to shoot the people that developed the idea for them.

PS- just remembered another problem. I think some kind of popup installed something in my computer (or maybe it's this new MMhell thing), but in many of the topics I read on this site (haven't really noticed it yet on any other sites), words are hyperlinked. Like in a thread I just read there was the word uncaring, and caring was hyperlinked. Is this new to the MMhell thing, or am I bugged even more than I thought?
