Microsoft Security Essentials (MSE) - is one of the Best Antivirus for Windows operating Systems:

               World's biggest Software company, Microsoft created Microsoft Security Essentials. It is an antivirus software (AV) product that fights malicious software (malware), including computer viruses, spyware, Trojan horses and rootkits.


Microsoft Security Essentials is built for individuals and small businesses, but it’s based on the same technology that Microsoft uses to protect giant businesses (security products like Microsoft Forefront, the Malicious Software Removal Tool, and Windows Defender). We have a whole team watching for new threats and coming up with ways to squash them.

Microsoft Security Essentials Features:

Real Time Protection:

          Real-time protection means addressing potential threats before they become problems. Alerts notify you when spyware, viruses, or other malicious software attempt to run or install on your PC, and suspicious files and programs are prevented from opening

Automatic Action against virus or corrupted file:

           When Microsoft Security Essentials determines a possible threat on your PC, alerts notify you of the threat. Threats are categorized as Severe, High, Medium, or Low, and you can choose whether to ignore, quarantine or remove the item from the system.

           1. Quarantine: 
                                   Microsoft Security Essentials blocks less severe threats and moves them to a quarantined queue where you can elect to restore or permanently delete them. By placing an item in quarantine, you can test the effect of the item’s removal before deleting it from the system.
           2. Remove: 
                             This action permanently deletes the item from the system.

           3. Allow: 
                         This action stops Microsoft Security Essentials from detecting the item in future scans by adding it to the Allowed Items list. You can remove items from the Allowed Items list at any time. 


Windows Firewall integration
           Having an active firewall is part of securing your PC. During setup, Microsoft Security Essentials scans the PC to determine if a firewall is active on the PC. If no firewall protection is present, you'll be given the option to turn on Windows Firewall.
