P)leae be advised that over the last week or so, I have been getting periodic messages in a pop-up dialog box waning me that Windows Firewall has been breached and all my system files have been deleted. With an instruction to click on an "OK" button.
The graphics and the English diction are just bad enough to catch the notice of a savvy literate person. It might catch the less-than wary, or ESL readers awry, though.
Shutting down the session window is enough to unlock the dialog, all traces of which vanish into the ether.
Back tracing through my firewall, it seems linked to one of the ad streams, when they load in the sidebar. AdChoice seems to be the culprit. The banner ads seem ok.
Sadly, I have not yet screenshot this annoyance.
For reference, I am using the most current Firefox, with NoScript running, this on a Win7 64 bit Pro desktop through ZoneAlarm for a firewall, and AVG.
