what gall! 948? they know dern well you hit 1000 last week!

our business computer got hit with something like that after one of the employees went to a reverse directy type of site. ( had written down a phone number on the message pad but no name ) ( plus that computer tracks all web sites it goes to...so it wasn't from going to a naughty site)

we lucked out that running adaware caught it and removed it.

is it a pop up while you are online braindrain? if so, clean out your cookies...toss the choccy ones my way..clear out the temp folders and run whatever program you use to get rid of this junk...adaware...spybot...
add the url of the pop up web site to your blocked list of sites if you are using IE.

hope this helps.
