Microsoft Security Essentials - free antivirus software for users who license Windows. The program has a very friendly and intuitive interface. If you have not performed an update or checkout interface turns red.
Anti-virus software updates virus databases once a week. As a result of testing http://AV-Test.org anti-virus software detected the virus and 98% is rated "very good." From personal experience, I can not say if it will work, because with virusovannymi files have no work habits. But sometimes a flash drive something catches.
In my opinion, a disadvantage is the fact that the program takes too much memory, and sometimes very much CPU time, although this is rare.
The program can scan files and directories, it is to monitor real-time protection, a scheduler, quarantine viruses and log about detected malware.
Microsoft Security Essentials - a pretty good program, easy to use. This antivirusnik Housing good toll free analog design.
