If all else fails, a clean install may be the answer. As well as unloading all of those no longer needed temp files that may be lingering around. Defragging your computer makes a difference. Perhaps a out of date software that's not needed anyway? At any rate, something's running wide open that shouldn't be.Īnd don't forget the obvious. Usually, the answer will be in there somewhere, as it clearly shows how much resources each process is using.
You can open up the Task Manager while MSE is running, to see what processes are going on. I recommend it to all who asks me about a good, free AV that won't bog their computer down. MSE is perhaps the lightest AV on the market, even on my low spec desktop, doing a full scan only used about 25 to 30% of the CPU & less than 2GB of my installed 4GB RAM(with whatever other services were running). Usually, once installed & updated, it speeds it up, especially if a 'heavy' AV/IS suite was previously installed. I have to agree with the other members, I've never seen MSE drag down a computer to this date.
