Our Feb. 16 Top Story reviewing resource usage among six free antivirus tools generated a flood of reader mail.
Here’s some follow-on discussion about AV resource use, based mostly on questions and comments about Microsoft Security Essentials.
Did Fred miss the point of MSE’s problems?
Reader Kumar’s letter questioning my performance conclusions for Microsoft Security Essentials (MSE) is representative of many e-mail responses to our Top Story, “Is your free AV tool a ‘resource pig’?”
- “I enjoyed Fred’s article. However, I think it misses the point of why some people think MSE is a hog.
“It’s not about the RAM it consumes on an idle computer. Nor is it about how much time it takes to load. MSE isn’t heavy, it’s busy — overly busy.
“The main issue is its pre-emptive scanning, scanning even files that the computer doesn’t otherwise read. Just browse to a folder with lots of files and see for yourself.”
I didn’t see any scanning problems in the test setup; nor have I seen them on my personal-use and office PCs, all of which run MSE.
But I have no trouble believing that MSE — like any other AV software — can and does cause slowdowns in some PC setups.
