What is this?

Hi

I was trying an addon for IE7 and it was brilliant but one of the search sites, which I had never heard of, kept popping up and I was searching "TEST" for making it a more defined search when my av (Avira) popped up saying this:

AntiVir has detected 'JS/Iframe.1094'
in the file
C:\Documents and Settings\user name\Local Settings\Temporary Internet Files\
Content.IE5\GWHMV3R4\date[1].js

Ran a full scan after that with Avira av, AVG AS and SAS, nothing else so I presume it stopped it there, went to the KB but no info on what JS/IFRAME is? Went to a few other vendors sites and found nothing, after a search I found a similar one but the number at the end was different. What is it?

I have open in an iframe disabled but what worries me most is I was actually just on a search page and not on any website! I usually use Fx for browsin' but do take IE out now and again plus a couple of others. Could this be on my 'puter somewhere?

Thanks :major
