its currently a hit malware scanner and does lots of work even better than windows defender. can also be used alongside other antiviruses even kaspersky.it's the bomb
Just installed in the place of AVG, a pretty good Antivirus program. I am impressed with the speed of the download and installation. It seems to use very little system resources and since it is just version 1 and MS will continue to improve (I hope) it should get even better. I would recommend it over most paid AV programs because of their resource hog ways. If you have been using Norton because it came as a trial on your machine, give this one a chance. I know you'll be pleased.
