I have been plagued with this trojan for some time and tried every program to kill it to no avail. It is a reg key that disables task manager and regedit among other ails. It can be quarantined with ad-aware but reinstalls on restart. I have had great success so far with RegRun. It has an option to prevent any program from starting up. So far so good-no ciadoor on my next ad-aware scan. The website is www.greatis.com/security and has a full function 30 day trial if you go to "downloads" at top of page. No credit card needed.
