MSE is a very good antivirus; I used it on my old notebook with Windows XP and now I use it on my new notebook with Windows 7. It is light and effective, and consider that I visit all sorts of sites and download and test all sorts of software. MSE never failed to warn me of potential/real viruses and malwares.
I just added a (free) tool that makes bi-directional the native firewall that is included in Windows. Regards.

Poor detection and removal. Slows your computer down far too much as it scans every program you open

MS came 17th out of 18 AV's on 'AV Comparative' (March - June 2013) tests - Enough said really

MSE today lags behind almost every other AV in virus detection, as mentioned by some of the guys here. It also requires manual updation, as the automatic update never works. Microsoft claims that the AV tests are not realistic, as the tests use sample viruses, which have infected only a very small fraction of the total number of PCs running Windows. So it is their word against yours. Apparently MS is on a self destructive path, as you can see from the quality of their AV product and the terms they are imposing on potential users of MS office today.

My personal suggestion is to use AVG or Avast if you need free protection, and have a fast enough PC/laptop with Core i3 or better. I still use MSE as my primary AV, as I find substantial slowing down of my old laptop with either of the other AVs. I also have Comodo firewall installed, with Defence+ turned ON. This gives me additional protection of sand-boxing, as well as a secondary AV (Comodo AV detection is built in), and there has been no infection in the last 4 years that I am using my Pentium based laptop with Win7. In addition I run Malwarebytes scan every week to double check on these two. Three stars only because it does not leave my laptop panting for breath.

I wasn't sure whether to use this or not so I gave it a test drive on one of my laptops and I must say I was very impressed. I experienced 0 slow downs on the laptop. I can only assume it does what it's supposed to do because I don't usually get infections on my PC's. So far so good, it seems to be very seamless.

@niknetpc - At no stretch of the imagination could MSE said to be 'still the best' as until recently it's detection rates were abysmal.

MSE is better than it was but, (though it had lots of room to improve)
slows a (this) PC down & still lags regarding detection compared to the (free) competition.

Personally I wouldn't use MSE as my primary AV solution as I don't think it's good enough, though it seems others disagree ~

this is not really good..... have you looked at the expert malware testing sites....
Microsoft Security is near the bottom..... 59% out of 100

Still the best full featured free antivirus with no ads asking to buy full version. Setup and forget, never slow PC. Some guys just affiliate nod32 and other paid AV etc or just need upgrade their ten years old PC :)

Been testing this software for a long time and it has NEVER slowed down my PC.
Best there is for free!

Slows the computer down considerably. I mean it REALLY slows the computer down. Somewhat effective on virus protection, but then again so are a lot of others that don't slow the machine down like this one does.

If you want free, get Comodo. If you can handle the $35, get Eset NOD32

I'll stick with Avast for now. In the future I may switch to this.
