I upgraded my XP machine to Vista Home Premium. Before doing the upgrade, I had been using an anti-virus program called AVG version 7 from Grisoft.
After installing Vista I discovered that AVG would no longer work, so I went into Control Panel, Add/Remove to uninstall AVG. The operating system, Vista, went through the process of uninstalling, stating at the end that AVG had been uninstalled. However, when I checked, AVG was still there. I tried uninstalling AVG several more times, and every time Vista told me that it was uninstalled - but it wasn't, and it won't run.
Why wouldn't AVG uninstall? How can I get it to uninstall? Thanks.

Try reinstalling AVG, then uninstalling.

Thanks, but I tried that. I downloaded a new copy of the program from Grisoft, tried installing it, but it would only allow an uninstall or repair option because the original version was still on the computer. However, when I chose the uninstall option, it did not work.
I turned off UAC and tried uninstalling AVG again, still did not work even after I downloaded a new copy of AVG. Then I tried deleting the files in AVG one at a time. That didn't work either (at least for EXE and DLL files. The system said I didn't have permission.
So now I'm really confused. I turned off UAC and am still getting all of these PITA Vista messages.

high light it, then click on launch. Now re-boot. UAC is now disabled. Go back to run/msconfig/startup and take all the check marks out of anything associated with AVG. Re-boot and if you have AVG icons in the taskbar, right click on them and exit. Now delete AVG. HTH Frank

If you had read the instructions on the AVG download pages, you would have seen something like this, Don't uninstall, start the install and when you are offered the choice of install or repair install, choose the repair install. "Retired"

Thanks, I'll give it a try tomorrow AM.

Thanks, Frank. I'll try it in the morning.

I agree with Charles. I would try doing the "Repair," and then see if the original problem with AVG was fixed or not. If it was, you're good to go. If not, I would next try the "Uninstall" option.
BTW, I am running AVG7.5 Free on Vista with no problems at all. It is certainly compatible, and I can't imagine why you are having so much trouble uninstalling it. Doing so certainly shouldn't require turning off UAC.

Thanks. Actually there are 3 options listed: (1) Add or remove components, (2) Repair, and (3) uninstall. There is no "Install" options as long as an existing copy of AVG is still on my hard drive. The Grisoft webpage where I downloaded AVG had no list of instructions about how to do what you suggested.
I tried option (2), "Repair". It went through the steps and there were no error messages, but when I tried to do an uninstall, it went through the processed almost instantly, ending with a "Finished" message immediately - but IT DID NOT UNINSTALL.

To uninstall it, you first have to disable it(TURN ITOFF). It has NOTHING to do with the UAC. It is quite simple, you can not uninstall something that is still is running, which an anti-virus always is. Right-click on the icon, there should be an option there to disable it Turn it off, then uninstall it.

Well, I'm getting a lot of good suggestions. Unfortunately not a one of them has worked. Yours, for example, is good. But I had already disabled it before trying to uninstall. - and it would not uninstall.
I'm beginning to think my Vista installation (an upgrade from XP installation rather than a clean install) was somehow flawed. I'm going to delete the hard drive partitions, re-format, and then install Vista as a clean install. That way, AVG and all other previously installed software and data files will be gone and will force me to re-install them from scratch.

Thanks again, Frank. I followed your instructions exactly, but unfortunately nothing changed. I am going to try a clean install of Vista. Of course I will then have to install all of my other software, including AVG, from scratch. I think my upgrade from XP to Vista must have been flawed in some way.

Good Idea! if more people would do a clean install instead of upgrading over XP (or an older OS) there would be alot less moaingin and groaning. I have never upgraded over a prior OS. Sure it takes more time backing up and reinstalling files and apps......but trust me it saves a person so many headaches and time in the long run.
Even with prior Upgrade version disks you could reformat your hard drive and do a full install.
I don't think many people knew you could do this so it got them in the habit of just upgrading over an older OS.

I agree. A clean install is definitely the best way to go.

I agree with you Dave; upgrading is a troublemaking waste of time. And I never use dual boot, put each OS, XP Pro and Vista, on a different computer.

I setup mine as dual boot, but not from an existing/longtime install of XP. I clean instaled XP Pro, did all updates, then installed a second HDD and clean installed Vista Ultimate. I did several benchmark comparisions before installing any additional software to either. XP Pro boots a few seconds faster on identical hardware. Both work as designed. I just don't like the new design. Even with 256MB Video RAM and 1.5GB RAM, Vista isn't to my liking. I set to classic menus & 'adjust for best performance'. That disables all the sliding menus, scrolling & shadowing in both. Thank GOD it's still available.
