MsMpEng.exe(Windows Defender)

[Guest FC, Dublin]

Why does MsMpEng.exe use up all of my cpu when scanning? And what can I do

about it?

1. Microsoft has established separate newsgroups for Windows Defender

support and comments. This is not one of them.

 

See

http://www.microsoft.com/athome/security/s...ps/default.mspx

 

TIP: Access these newsgroups using your default newsreader, not your

browser. See instructions on above page.

 

2. Unexplained computer behavior may be caused by deceptive software

Run a /thorough/ check for hijackware, including posting your hijackthis log

to an appropriate forum.

When all else fails, HijackThis v2.0.2

(http://aumha.org/downloads/hijackthis.exe) is the preferred tool to use (in

conjunction with some other utilities). HijackThis will NOT fix anything on

its own, but it will help you to both identify and remove any

hijackware/spyware with assistance from an expert. Post your log to

http://spywarehammer.com/simplemachinesfor....php?board=10.0,

http://forums.spybot.info/forumdisplay.php?f=22,

http://aumha.net/viewforum.php?f=30, or another appropriate forum for review

by an expert in such matters, not here.

 

If the procedures look too complex - and there is no shame in admitting this

isn't your cup of tea - take the machine to a local, reputable and

independent (i.e., not BigBoxStoreUSA or Geek Squad) computer repair shop.
