It appears that a Trojan has zeroed in on Firefox on my computer; the same thing is NOT happening when I run IE -- what can I do?

For a few weeks now I've been getting popups on Firefox randomly and if I let them load they are ads (even though I have ADP running). I've been annoyed and clicked them off. Then yesterday I got a warning (in red, bottom right corner) from my antivirus software stating that I have a threat of a trojan, that the connection has been terminated and quarantined and no other info on what to do. I opened up IE and have no problem on any site. On Firefox, every site gets the same antivirus warning in red.

Download the free version of Malwarebytes from http://www.malwarebytes.org/products/malwarebytes_free using Internet Explorer and choose to Save it to your desktop.

Then double click to install it. Do a full system scan and remove anything it finds.

Then try using Firefox again. I can't see what version you're running because you appear to have deleted that info, but assuming it's 3.6.17, go to Help | Check For Updates to update to 4.0.1

Actually, I have Malwarebytes and ran it along with C Cleaner and my antivirus program -- Eset Enod 32 -- last night. Nada.

Here's what shows for my version of Mozilla: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.17) Gecko/20110420 YixianosaurusA1pp2878244815 Firefox/3.6.17 ( .NET CLR 3.5.30729) SearchToolbar/1.2

How can it be Mozilla 5 when they're promoting 4? Or is it Firefox 4 they're promoting now? And what's the difference?

Now what should I do?

That figure "5.0" has nothing to do with the version of Firefox you're running. The version you have installed is 3.6.17

Be very careful running CC cleaner. You can totally screw up your installation if you delete the wrong value.

What was the result of the Malwarebytes scan? You'll find the results in the Logs menu and it will be the bottom one. See screenshot.
