    Microsoft Security Essentials does exactly what it is made to do.. "Re-actively stops .exe and other files from doing things on your computer and registry"

    it doesn't "Proactively" find viruses which is probably why you say its terrible.. other 3rd-party anti-virus programs do this.

    I agree that you must use other apps to search for things but Microsoft Security Essentials atleast prevents registry and standard virus procedures.. It also removes viruses pretty well. I've been to far too many "untrusted" sites and have not been ever hijacked or had a virus. But I also know what I'm clicking.

    I'll give you the other programs I like are ESET online scanner and Hitman Pro and Malewarebytes.

    But whlie microsoft definitely has its shortcomings, i would hope that they know what processes and behind the scenes files to be checking/look at to see viruses etc..

    To handle with this kind of problem, first go to Disk Clean up by right click and run as administrator. Now check your system properly and clean all junk from it using some good cleaning software. Then defrag your hard drive and run safe boot. Hope this helps.

    I've been strangely getting this problem over the last week. My HDD is showing 100% usage and my PC runs at a painstakingly slow pace that I almost feel like throwing it out of the window!

    I've tried disabling windows search, defrag, auto maintenance and even full scans but nothing.

    The problem will go away for 5 minutes and then start again. It's driving me insane!

    On Windows 8 or Windows 10. If Norton 360 or Norton Security suddenly goes to 100% disc usage every thirty days, it is because by default an automatic full system scan is taking place. After a year of talking to Norton support I finally figured this out myself. On Norton Security, go to Settings / Antivirus / Scans and Risks / Full System Scans / Configure /Edit Scan / and click do not run this scan.
