Extreme Messenger also works with AIM 5.5 (ad removal is still in the works though): http://www.ExtremeMessenger.com
I wrote a tool to remove this virus/adware tool automatically:

Use Extreme Messenger (http://www.ExtremeMessenger.com). It adds a URL box to the bottom of the AIM Today window so you can visit any site you want just by typing it in. 🙂
Registered users of Extreme Messenger (http://www.ExtremeMessenger.com) have access to all these smiley styles. The Extreme Messenger version will automatically insert the smiley into the IM when you select one, and can optionally send the IM when you click the smiley as well.
Extreme Messenger 1.6.1 should fix all the problems you are having, especially when using Windows XP. I know this topic is old but I just had to reply. 🙂
