Why is my facebook site so slow after installing AVG?

by pcwhisper / April 21, 2011 2:21 PM PDT

IBM-dt-XP...Loading AVG free was not easy and running AVG PC tune-up was an accident waiting to happen! But...I got it accomplished... why make it so difficult to download a program? Now after all this...my facebook account will not work as it should. If I page up or down it takes forever for the page to move. This has been a flustrating experience to say the least. At one time AVG was simple and trouble free...WHAT HAPPENED?

Hello pcwhisper,
I was not able to induce the situation in my environment, unfortunately. Could you please try to pinpoint which AVG component is slowing the Facebook page down by disabling them one by one as described in this How-To article? Are there any other websites affected too?
Also, please provide us with an msinfo32 output and with a complete list of used browser addons/extensions (including their exact versions). As it is not possible to attach files on this forum, please upload the msinfo output to some online storage service and post here a link to the uploaded file.
Thank you.

I found the problem but now another question.
by pcwhisper / April 22, 2011 5:42 AM PDT

The problem is with Link Scanner...when Search Shield is not active...my Facebook page works fine, Do you still need the msinfo32 output to correct the problem or should I just leave the search shield turned off?
Thank you so much for your help!

I am having the exact same issue, having installed the latest update yesterday (5/7/2011). Facebook gets stuck for several seconds at a time every time I do something in FB, even something as simple as scrolling down. On Windows 7, IE8.

Thanks, but I can't use the "msinfo32 output" instructions as specified in your link - my home PC is Windows 7, but the instructions are for versions of Windows prior to 7.

Windows 7 comes with that program. What happened when you ran it?

I see you acknowledge there is a performance issue, but I don't understand what the workaround is? How do I disable the AVG search shield ???
In simple, easy to follow terms please

Hello newmoose,

1. Open Internet Explorer.
2. Click on Tools - Manage Add-ons.
3. Click on AVG Safe Search addon and then click on Disable.
4. Click on Close and restart Internet Explorer (Close it and open it again).

If you do not see Tools in step 2. press left alt key to display it.

Thank you

Same issue, resolved by disabling Search-Shield
by DarrelH / May 15, 2011 3:07 PM PDT

I have the MSInfo32 output. Give me a location to send it, and it's yours.

Freshly rebuilt Win 7 Ent, 2.9 WEI, thought speed drop was due to IE9 upgrade (after I installed AVG). Rolled IE9 back, crazy slow IE speeds remained. Facebook was the most highly impacted site that I'm aware of, but performance was less than stellar elsewhere as well.

I'm a software dev w/QA background and am willing to work with you to test/report on the problem.

Hello DarrelH,

Firstly make sure that your AVG is 10.0.1375.
If not it is possible to perform repair installation with 1375 installation package.

Afterwards please upload the MSinfo file to your favourite online storage service and provide us with link.

Also provide us with all AVG log files right after inducing the issue (Browsing Facebook).
Log files location:

Compress the files and upload them in one archive with MSinfo output.

Thank you for your cooperation.

Since my reply, I decided to go back to IE9, and it's been fine. Got the notice of your reply today, so I checked. I have 1375. I'm also running 64bit, so your path is not valid, but there is no log directory under the (x86) folder either.

I re-enabled Search-Shield, ensured all browsers were closed, but could not reproduce the problem. I rebooted, went back into IE9... still unable to recreate the issue.

Here is the sequence from build to now: If your 1375 update on 5/10 resolved the update, I won't be able to recreate the slowness.

5/1 - Build fresh Win 7 Ent 64 system.
5/1 - Installed AVG (1325?)
5/2 - Installed IE9 - Slowness observed
5/9 - Rolled back to IE8 - Slowness still present
5/15 - Disabled Search-Shield - slowness went away
5/22 - Re-enabled Search-Shield - no slowness observed

I'm keeping it enabled, and will monitor performance. If the slowdown reappears, I will follow up providing you give me the updated log folder location for 64bit systems.

Log files location
by Dusan_AVG / May 23, 2011 6:20 AM PDT

Hello DarrelH,

This location is valid for both x86 and x64 systems.

Please note the difference of path from C:\Program Files or C:\Program Files (x86).

It may be necessary to display hidden files and folders to be able to see ProgramData folder.

Thank you

Uh... you sure?
by DarrelH / May 23, 2011 2:25 PM PDT
In reply to: Log files location

Hidden folders are viewable to me. On a whim I even enabled viewing system folders. No dice. I accepted all defaults during install, and my folder structure doesn't match what you are claiming should exist.

"C:\Program Files" contains NO AVG*
"C:\Program Files (x86)\AVG\AVG10" contains NO Log folder.

And now you have me doubting your ability. Please restore my faith in this thread.

I see you guys aknolwedged the problem in another reply. Funny, didn't really seem to be in the release notes.

In reply to: Uh... you sure?

Hello DarrelH,

please note that Dusan advised to search in the C:\ProgramData\AVG10\Log folder while you appear to be looking in Program Files (x86). I'm quite sure that this system folder is there (on Windows 7 x64), because it is crucial for proper applications run. It is hidden by default.

Please be informed that Release notes contain only list of already fixed issues for the relevant AVG program version. No list of known issues is available. There are weekly updates on the most reported issues in this AVG Free Forum thread though (titled as Weekly Overview):

Thank you.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
