I already use Microsoft Essential Security (MSE) in a month. This antivirus is a free product provided by Microsoft for all people in certain countries. With the file size that is only 8.6 MB, I can download and install it to the computer quickly.
This antivirus has a very good real time protector, especially when I was browsing the internet. MSE can block and handle all malware, viruses and also avoid attacks from denial of service which can be deadly websites. Besides that Microsoft continues to update the virus definition database every day so I can keep update the virus databases any time to protect from new viruses.
