AVG unbearable Internet slow down

I used the tool to completely remove AVG, restarted and reinstalled from the link you sent me.  The problem with not all eBay item images loading, slow Facebook and websites not loading is still there.  As soon as I disabled the Email and Web protection components, websites start loading instantly again.

Hello S De bono,
We apologize if an AVG product did not meet your expectations. Our main goal is to keep our customers happy. However, AVG web protection is not slowing down/blocking internet connection. In this case, I request you to check the AVG programs you have installed on your computer (control panel > programs and features), also I request you to repair AVG Protection (http://support.avg.com/SupportArticleView?urlname=How-to-repair-AVG), update (open AVG Internet Security > menu > settings > update) it one more time and reboot your computer once. After reboot, please check if your internet access are working fine with enabled AVG Web protection.
Best regards,
Alok.

Just a note to warn users and also notify AVG developers.  I tried the 30 day free trial of the AVG web protection and it slowed down my internet speed to dial-up levels.  I have an ADSL connection, run Windows Vista with 4G RAM, Firefox (latest) with UBlock Origina and Privacy Badger plugins and AVG (always updated).  I initially blamed my ISP or some malware, but disabling the email and web protection solved the problem after a week of useless trouble shooting.  Please test this stuff before releasing it, and do not blame me for using VISTA, it works quite well for me.  I have a limited budget and upgrading takes its time.

Yes I did, but the problem persists.  Only disabling web and email protection works.  I do not think I need email protection because I do not use any email clients.  I only access webmail.

Thank you for the information.
I request you to perform reinstallation of AVG Antivirus free once.
1) Please click on this link: https://share.avg.com/steam/PSP/AVG2017/AVG_Clear.exe to download the AVG Clear tool.
2) Run the tool and click Yes twice when the prompt appears.
3) It will take you to safe mode and the clear tool window will appear. Tick the check box to "Uninstall Zen and Framework" and click on remove.
4) Once the removal is done, restart computer option will appear. Click on it and it will boot into normal mode again.
5) Run the AVG removal tool that is mentioned on this article: How to uninstall AVG software once which will completely remove all the traces of AVG. If no AVG program is shown for the removal, please click on "Run Anyway" to proceed with the removal.
6) Click on this link: http://files-download.avg.com/inst/mp/Antivirus_Free_1817.exe to download the AVG Antivirus free installation file.

If the the issue persists, do let me know.

Thank you for the prompt feedback.  I did like you suggested and removed the AVG Web TuneUp.  Prblem persists.  On eBay not all images load, no matter how many times I refresh the page.  On FB messages will not load.  Other websites take forever to load.  If I disable AVG web and email protection, everything works fine.  I will use the support pages like you recommended.  Thanks

Thank you for informing that it worked once the HTTPS scanning is disabled.
If there is any issues in accessing websites, do let us know.

Hello S De Bono,

I am sorry to hear that the issue persists. In this case, please follow the below steps and check if that fix this issue regarding websites not loading properly:

Open AVG Internet Security\AVG AntiVirus free->Menu->Settings->Components->Online shield->uncheck "Enable https scan".

Please check if websites work fine after unchecking this option. If you face any difficulties, feel free to contact us.

This worked for https connections.  My browser forces https where possible so this solved the problem on most sites.  They are not checked for viri any more but https should be more secure anyway.  Thanks
Free version so far.
