Windows 7: All web browsers stop downloading data every few seconds

For the past few days, I've been having a problem with my internet connection.
When trying to access a website, my browser stops opening the site after a few seconds. Instead of going to a page reading "the connection has timed out," the page continues to load at a rate of .01 kb/s.
I've read that such problems can result from anti-virus programs, so after running scans with both McAfee and Malwarebytes, I disabled them both.
For about a minute, everything returned to normal, but then the problems started again.
I've also entered "netsh interface tcp set global autotuning=disabled" into command prompt, which had no effect.
There is one other Windows 7 computer on my network that it experiencing no problems. There is also a Mac and an XP on the network.

Hey Blobman000, and welcome to sevenforums!

Let me see if I can help you with this problem of yours.

• Have you done any editing of the windows registry? There are commands, such as the one that you posted, that windows has preset and that I recommend not changing. If you are able to, try and change back to normal any of those settings that attempt to make the internet "faster"
• I will link you to another thread. Try and follow all of those directions and see if that is able to help you solve some of your problems: Internet speed suddenly slow?
  

If none of this seems to be working, then we will go from there. Hope we can get this figured out as soon as possible. Good luck

Unfortunately, the fix described in the other thread did not work.
The command in my original post is the only one I've used.

There were a few details I failed to mention in my original post:

I've tried using Chrome, Firefox, and IE, and all of them have the same problem. However, Steam (a program for purchasing and managing games) has a built in web browser. As far as I can tell, the Steam browser works fine.

After the problem started, I started a 60 MB text download. The download would run at normal speeds, but the download would freeze frequently, so I would have to pause and resume the download every few seconds.

Other than the test download, the only file I've downloaded recently is an update for McAfee, which was just a few hours before the problem began, which leads me to believe it is somehow related to McAfee.

Thanks for the help so far.

Blobman000,

You may very well be right about that. That program causes quite a few problems on this forum. Try this method:


How to uninstall or reinstall supported McAfee consumer products using the McAfee Consumer Products Removal tool (MCPR.exe)

Thanks for your help.
Everything started working right away after running the McAfee removal tool.

Glad to be of service, and happy that it is back working
