Slow Internet After Apple Update

After the latest update to my Apple computer, the internet speed slows to a crawl.

Full antivirus software has been run and completed without a virus detected.

One suspicious connection is to and a search reveals Amazon.EU.IAD-Prod associated to EXP/Pidief.ebk.

Is the EXP/Pidief.ebk causing the issue? If so, how do I remove it?

Is anyone aware of the latest update to the Apple OS causing slow internet connections?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is it still fast when you go to  Which browser are you using?  I've found that Safari had slow access to certain pages and was not rendering some pages too, but everything worked in Chrome or Firefox.

Slow all over the board. When this Apple computer is turned on and connected to the network, all computers (10) connected to the network begin to have very slow and intermittent internet connections.

My guess is that the new Photos app is uploading all of your photos to the cloud. Did you turn on iPhoto cloud library? If so, go to the photos app > preferences > iCloud > and click pause for a day and see if that improves your speed.

You can also use the network section of activity monitor to see what's using up your bandwidth.
