a248.e.akamai.net ???????

Well, I'm learning from your posts today.

mrtstub.exe appears to be some leftover remnant from the Windows malicious software removal tool, included in windows udpates.

(That was cute that the color font followed my cut and paste)

All though some sites say it needs to be removed immediately...I get the sense that they are trying to peddle software...which is why I would just love "one" malicious process database w/o all the B.S.

I digress. It's recommended to run the removal tool again from Windows update. Or try to manually navigate to this folder and delete the .exe through performing a search on mrtstub.exe.

Funny how the most innocuous posts can be so difficult.

a248.e.akamai.net is a fast caching service that many large companies use to store their update lists and provide secure connections, like Wells Fargo. The following are some cut and pastes:

"Akamia is a fast caching solution for websites whiuch have a great number of hits. These websites store there gifs and seldom changing popular apps at this cache hosting company. Numerous companies such as McAfee.com, Wells Fargo, B of A etc. post data and programs to Akamia. McAfee posts there DAT files at this location to support the user community in grabbing the latest DAT when a new virus threat hits. Several years ago McAfee ranked 23rd out of all websites in terms of activity. At present many companies would require 3 to 10 OC4 transmission lines. An OC4 is 28 T3's which is 784 T1's) to handle the volume of traffic. Many companies would not be able to stay in the .com world without Akamia."
