virus possible?
 

We are getting an unconfirmed report that someone may have loaded some form of keylogger into a ui loader. This is very suspicious and may be a hoax. The person claims it logged his key strokes, stole his passwork and two other accounts. Someone then logged in and wiped three characters and disbanded a lvl46 guild. The person claims he was loading some sort of Power Bar UI. Like I say, we are very suspicious of this person but want to track this if there is a possibility.

If he merely installed a UI and went on playing, no - it's impossible to put a keylogger into a UI mod.

If he was using a non-trusted auto-updater, it's potentially possible.
