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.
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?
