Windows Live One care
By DeDee onThis anti virus came as a bonus when we bought our computer. We bought our computer last year.
I have had other anti viruses before. Including Mc fee and Norton. but when I had those, not once did an alert come up about a worm, Trojan etc. I know what your thinking that's a good thing. However with this anti virus I have had the alert come up a few times, within a year. Stating that it was caught. This is without the scanner running. Once it was removed or quarantined. It says to run scan. This anti virus obviously works well. I like knowing my computer is safe 24/7.
Our year ran out a few weeks ago. Needless to say that we didn't waste time renewing it.
Like other anti viruses we get updates and can set the anti virus to scan hourly, weekly, monthly etc. It also alerts you if you're not protected, for whatever reasons, power outage etc. It also gives you a popup to whether you started a program or want to continue.
If you are looking for an anti virus that works. This would be the one that I highly recommend.

I'm so glad that this is working for you!
I like it that you are responsible enough to care about running security software. I beta'd One Care Live and liked many of its features. You chose well DeDee
Nice to know it works great. The price is worth it to protect your pc. Like you, I haven't been impressed by Norton or McAfee.
