Symptom: When ran Internet Explorer, I got the following JavaScript error:

HijackThis Report: I ran HijackThis on my friend's system and saw this line:

O2 - BHO: WebBar Class - {EE392A64-F30B-47C8-A363-CDA1CEC7DC1B} 

Quick Research: I did a Google search on "htwtb.bin" and located the following related message:

I did a rescan using hijackthis and removed the line below. I had 
removed the other backup files in hijackthis to another location so 
I knew that the backup file from this rescan and fix would be the 
only one there in case I needed to do a restore. The web search tool 
is gone AND the IE Scripting Error message no longer appears on any
