High CPU Usage of Microsoft Security Essentials

You should add some “exclusions” to the scan settings of Microsoft Security Essentials. Refer to this article from http://www.howtogeek.com/howto/35332/antivirus-slowing-your-pc-down-maybe-you-should-use-exclusions/


What Files Should You Exclude?

The general idea is that if you have some applications that are writing to the hard drive constantly, you should probably exclude the folders they are writing or reading from, as long as those applications are trusted and safe.

For example, if you’re using a virtual machine, which does both reads and writes from the hard drive on a fairly constant basis, you should make sure your antivirus application is not scanning those files and folders. Here’s a few examples of some things you may consider excluding:

  • Virtual Machine Directories: If you’re using VMware or VirtualBox, you should make sure those locations are excluded. This is actually what prompted this article, and probably the only significant performance boost out of the things we’re mentioning.
  • Subversion / TortoiseSVN Folders: Have you ever tried to do a big checkout of a source control project and had it fail? There’s a good chance that it’s conflicting with your antivirus application. This one has personally happened to me.
  • Personal Photo/Video Folders: Got you have a massive library of photos or videos that you’ve taken with your digital camera? As long as you only use this location for files copied from your SD card, there’s no reason to be scanning it and slowing your PC down while doing photo editing.
  • Legitimate Music Folders: If you’re downloading music from shady sources, this does not apply. If you’ve ripped your own CDs or downloaded from somewhere legitimate like Amazon, then you can safely exclude your music folder.
  • Windows Update Folders: This actually comes straight out of a Microsoft KB article—you’ll notice that they don’t recommend it, because they can’t do that in case somebody writes a special virus for the purpose of suing them, but the same principle applies.
