I posted this some where else:

After you have your problem fixed, turn off the pop up window on your browser, clear your cookies (and set them to accept only sites you visit) and clear your cache.

Also delete your flash cache (Adobe - Flash Player : Settings Manager - Website Storage Settings panel)

Start using Firefox instead of explorer.

Make sure you update your virus definitions at least once a week.

Default What's with all the trojans getting in through Firefox?

Firefox seems to be a never ending stream of trojans lately, and they're not coming in through porn or torrent sites. The latest, which got in yesterday, came in as I was trying to access a webpage listing titles of films from the 70's. This page was the first hit from a Google search.

I'm usually fast enough to do a three finger salute and then kill the Javascript processes, but that didn't work yesterday.

I got the obligatory fake virus scanning screen, telling me I need to purchase their product because everything was infected and even the motherboard was about to catch on fire if I didn't act fast enough, bla bla bla...

And these buggers made it impossible to launch an .exe, so I could not get to msconfig to take the trojan out of startup before rebooting, and rebooting in safe mode did not help -- I had to rename my virus scanner to a different extension and then run it to get rid of this thing. Bah!

I'm at the point where I rarely use Firefox with Javascript enabled due to all these trojans.

In the meantime, I've had not one trojan get through Opera -- knock on silicon.

What gives with Firefox these days?

I use microsoft securty essentials, Win 7, ff4 and I think in the past couple weeks I've seen maybe one or two of these things pop up.

What security software do you use?

Try uninstalling firefox totally. Run CCleaner from piriform. Reinstall firefox with updates and never put the security level below med high and always ask for prompts before downloading.

To follow up with phwhit's inquiry... Do you have NoScript?

NoScript will prevent JavaScripts from running without your permission. You can browse websites and will get a notice that you need to have JS running. You have the option to allow or deny, temporarily or permanent. This one is a no brainer.

NoScript.net

Plus, it prevents a lot of advertising.

I'd never heard of NoScript -- I'll give it a try.

What you are describing is a new twist. These come from ads. For example you have a very legitimate site using a very legitimate ad network that serves ads for them. The "bad guys" are using the advertising service to distribute their crap. Apprently some of these ad networks are having trouble filtering them out.

Having said that I seen a few of these and while they were a PITA no issues with anything being compromised AFAIK.
