If you post a hijack this log, I can help you tomorrow. I will have to refresh my memory on the exact steps. It is something like
Using hijack this startup list to remove lop jobs from the task scheduler,
Deleting folders from documents and settings locations for all users and from program files,
and then fixing some R, o2, and o4 lines in the hijack this log.
If that's all you have, you will be very fortunate because this is much simpler to fix than some of the stuff that is going around nowadays.
It comes from installing messenger 3 with sponsors. You can take a first step of uninstalling messenger.
If you can work it out on your own, you can use hijackthis' startup list to look for 1-5 jobs similar to this in the task scheduler, A2864FEB9185C5B7.job and delete them, and
then post a hijackthis log.
We can help you from there tomorrow.
