I've made myself happy with free Avast on my Win 10 box and free Avira on my Vista box. Almost everyone offers a free trial...so try one and if you don't like it, move on to something else.

Many cable co. along with their internet service these days offer a free antivirus. I have Optimum and get the full version of McAfee.

I've used the free version of Avast for a number of years and it's kept me safe. I've never once gotten an infection, and it's caught a number of attempts.

Thank you everyone fot all of your input. I will check them out.

For normal every day users you honestly don't need anything other than Microsoft Security Essentials. https://support.microsoft.com/en-us/help/14210

Universal Iron Door, the sites that do independent testing and ratings don't agree with you. Most find the Microsoft product to be very much sub-par compared to others on the market.

Elmer J Fudd, these are paid by their sponsor. Microsoft has giant servers that large corporations use that are protect by the same anti-virus protect found in Windows 10. In case you do not know, viruses are discovery and report to Microsoft, not the McAfees and Nortons. Microsoft relays all their info to them afterwards.

My response never intended to state MSE was the best. It is adequate, however.

I use Panda FREE antivirus.......happy so far....it is adquate for my needs!

harry wild, you're very misinformed. I can leave it at that.

As just one place where you can get better information, check out PCMag. Yes, it takes ads, but the ads don't influence its editorial content. It's a independent and respected site. Among the many things it does is for security software, it tests and also summarizes the work of professional and independent testing labs.

There are organizations that the security software companies use to find and share danger trends and newly found bad actors but it isn't Microsoft.

Universal Door, the tests I found suggest MSE is not adequate. There are many better alternatives and many of those are free. I see no compelling reason to use MSE and risk having problems.

Elmer J Fudd,

Not that is important to you, but I am a MCSE and graduated with a MEE.

Do you work in the software industry? In the security sector?
