I recently got infected with Antivirus XP and sucessfully removed it (with Malwarebytes Anti-malware)

As far as I know, this rogue software was apparently installed when I clicked the 'X' to close a popup. I didn't see any kind of activeX prompt, I was using firefox, I have the latest windows updates installed constantly, I had McAfee enterprise running...yet I still got infected -- HOW?

Did McAfee not catch it because it's spyware and NOT a virus? What kind of AV shield will prevent this from infecting my other computers?

Also, does anybody know details on how to patch up the windows security vulnerability that allowed this to infect me? I wonder what the vulnerability is -- because I can envision other more malicious programs emerging that would do much greater harm than this one.

Here's a little tip I picked up right here at BP. Don't click on the X to close a popup window. Instead, right click on the entry on the task bar and close it that way. It seems that these malware creators know that most folks click on the X so they've set up a booby trap.

For more detail on how these types of infections install themselves, read Anatomy of a malware scam.

Many infections spread via Internet Relay Chat, by visiting underground web pages, adult, gaming or pirated software sites, and by using peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such sites may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The infection also spreads through emails containing links to websites that exploit your web browser’s security holes and by exploiting a vulnerability in exploiting a vulnerability in older versions of Sun Java.

The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
