A big hug and thanks to prince of egypt for his help. It worked. I hope that anyone who searches google for help with Agent H will find this thread and get help also. I have seen nothing that worked yet till now. Follow his instructions and be patient. It takes quite a few tries for the processes in task manager to drop one, and in my case the sysupd.exe file modified itself before my eyes. That tricky trojan....but I just repeated the steps and deleted them both eventually. Unfortunately I couldn't find that update.dat file with searches. So once you delete the sysupd.exe file and/or files (in moves around on the task manager list, keep looking for it) run your AVG again and it will be able to heal it this time. I am ready now to tackle another virus...let me at them!
