Hello Forum: I also am having a problem with AVG 8.0 I am running a Dell dimension 2400 WinXP, IE6.0 . Also using AdAware, CCleaner, SpywareBlaster and have all the latest updates for Windows and other programs. After I downloaded the latest AVG update a popup said I must restart computer. I did(5X)!. Yet AVG the tray icon kept warning that Update Manager was not up to date. I kept updating it but the problem remained. After a day of this I decided to Uninstall AVG and download a new copy. AVG Uninstall would not work. Kept getting message " Warning, internal error, Dialog with ID 'AVG4ESDLG' was not found in Setup". Now what? I downloaded REVO. It removed AVG 8. I downloaded another copy of AVG from Download.com in order to obtain it from another source other than AVG. All was well so far. I checked the AVG uninstall utility and it was working. No more error message. But then AVG told me to update latest definitions. After I downloaded the following update the problems with update manager and AVG Uninstall reappeared. This is a 6.9 or 7.9 MB update: "update/F8UI134R100vibin 15/16" Anybody have any ideas.? Will AVG update a fix? OBTW , REVO did the job when Windows ADD/Remove couldn't. Thanks. Any help is appreciated.
