huh.

I'm not sure which post/tab I clicked when it happened & it's the first time it's done that.
...I use
Webroot AntiVirus with AntiSpyware (all good stuff) and McAfee (dumb, but I got it free). I quick scan every day and full scan twice a week - a little overkill, I know, but I use this laptop for school and teaching, so not worth a risk. Not even the Norton AntiVirus 2009 (

) can get past my Webroot without being immediately blocked & quarantined. I just don't see it being something stored on my lap top. Hmmmmmmmmm.
Hopefully it's nothing. Possibly could have been my cat nudged the mouse/clicker and clicked something?... idk. I just wanted to mention it just in case.
