Pages load slowly.
It's been about a week now. Don't know if it's coincedence or not, but it seemed to have happened after all the Windows 7 updates last Tuesday followed by a McAfee update on Wednesday. But I first noticed it right after the McAfee update required me to reboot my computer. Suddenly ANY webpage I visited took forever to load (longer if there were lots of images and/or videos, like Facebook). I've rebooted several times, both the computer and the modem/router. I've flushed the DNS. I've cleared my browser cache. I've run CCleaner, Malwarebytes, and ESET's online scanning program. I've tried the unchecking of the ipv6 box on my network adapter. Probably a couple of other things that I'm forgetting as well. (Also noticed when opening my email program, it seems to lag as well when checking for new mail).
I just checked my PS3, doing an internet connection test (fine), using the web browser to go to Google (popped right up) and streaming a random show on Netflix (seemed okay to me). That narrows it down to something on my computer then and not necessarily the network.
Other than trying a few pages without McAfee turned on, I'm not sure where else to look to solve this issue.
EDIT: No dice. Turning off McAfee made no difference; pages still are slow to load.
