I removed ALOT Appbar (I have no idea what that was) and the AVG Toolbar, as instructed.
I also removed the "left-overs" from the previous AVG install.
The wireless, network connection issues may either be related to my trip to Puerto Rico or the fact that I recently changed the router and DHCP addressing scheme on my home router.
I certainly hope it is not a hard drive issue, that hard drive is fairly new (less than two years old). I do, however, back up my drives regularly to my home server.
The only thing that remains on your list is the “Display-Link” and “CCleaner”. Display-Link is a USB to HDMI “video card” so that I can connect my computer to my HD tv. Is there a way to figure out if that is my issue and fix it?
Also, I installed CCleaner to try and troubleshoot the slow issue on my own before coming to this forum.
