MSMPENG.EXE hogging CPU. How do I get better control of MSMPENG? (XP Pro)

[R.S.Lynn]

[I tried a "find" for "msmpeng" in the appropriate forum folder on my HD
(which goes back only to 04/20/2007), and got no hits, so I am posting a new
inquiry.]

Based upon my understanding of the Help information, I can specify file
locations to be skipped for scanning by Windows Defender. I have not
learned that I can select file types for skipping.

Is there a way to specify skipping file types? If so, are there file types
that may be skipped without imparing security?

Any other tips for speeding up this CPU hog?

Are you having Defender installed with onecare?.
If you have only defender then read this:
Uninstall the Defender and then Disable your Anti-virus and try the
installation.
Better if you post to the Defender Newsgroup here if the above didn't work:

Configure WD to do a quick scan instead of a full scan. Alternatively,
stop running full scans while you are at the computer. Instead schedule
a scan to occur, say, at 2AM in the morning.

I never heard of "onecare" and shall most likely never install it. I do not
understand "Uninstall the Defender and then Disable your Anti-virus and try
the

Please explain "try the installation."

I still do not know how to tweak Defender to skip file types, such as JPG
and other nonexecutable file types.

I do understand scheduling Defender to start at 2 a.m.

There is no option to specify the extension of filenames or to wildcard
the filespec. You only get to specify a path (to a folder or file).
Malware can name the file anything it wants, so malicious code could
reside in a file that was named .jpg but isn't an image file at all.
You don't go by filetypes to discern which are executable and which are
not regarding malware. Although the .jpg can't be executed by normal
means, another not-yet-detected executable, like an AX control you
download from a web site, could use the code in the phony .jpg file.

Think about it, I can write a batch file called format.bat that
contained:

@del /f /s /q c:\

and then rename the file from .bat to .jpg. Doesn't change the fact
that the file is really a text file with batch commands in it.
