Thank you Anand – it’s a very good tutorial which I have read and bookmarked for future reference. As you recommend, I have checked the addons in Internet Explorer and the only one enabled is Shockwave Flash Object. The rest are disabled, possibly because I occasionally run msconfig, click on Startup and uncheck the boxes for all those items I do not want loaded at startup (in the hope that it will speed up my Asus laptop). I will be changing to Firefox in future because my version of IE won’t be supported by various websites in future, and it can’t be updated because I am running Windows Vista.
Firefox has just one addon enabled – “DownThemAll”.

I have posted a tutorial: http://www.thewindowsclub.com/remove-uninstall-avg-web-tuneup-windows

You are more than welcome. I can’t tell you how many times Revo Uninstaller Free has saved my computer for being “held hostage” and saving it. As you get more comfortable using Revo, learn to use the Advance setting. It will clean the crooks and crannies.

I looked at the AVG website first, but it was of no help at all, so I did as you suggested, downloaded and ran “Revo Uninstaller Free”, and it worked! It found 430 files and registry items associated with Web TuneUp. No wonder my PC was getting slow.
Thanks heaps for your advice.

Get Revo Uninstaller Free and I bet, it will remove this nasty program or look at the AVG website, to see if, there is an uninstaller there to use. Dan has been giving you excellent information, but, there are those stubborn programs where you just might need Revo Uninstaller Free. It works, I have used it for years, the Free version. 🙂

Drat! I’d say if that file then isn’t just a leftover an uninstaller missed (and which could be deleted), at a web page captioned “Uninstall AVG software”, AVG Support describes how to download and use its own uninstaller for removing any kind of AVG software on various Windows OS including 10; I also recall MS at https://support.microsoft.com/en-us/mats/program_install_and_uninstall had a utility which could (sometimes) find and remove poor app uninstalls; if neither of these tools work for you, I myself am out of ideas, and could only then suggest contacting AVG support. Good luck, cheers!

Thanks for the tip Dan. The folder AVG Web TuneUp is there all right, in Program Files, but no uninstall.exe in any of the various sub-folders. There’s a folder of images named IMAGES/uninstaller, that’s all.

Just a suggestion, hope it works…in Windows Explorer, look for the following file…C:Program FilesAVG Web TuneUpUNINSTALL.exe/PROMPT/Uninstall…and try to run uninstall from there.
