Microsoft Windows Defender

By virtue of the rates of increased computer virus risks and heightened potentials of malware attacks in modern times, the momenta at which antivirus software applications are being reviewed, modified and/or churned out have been reconcilable. Most of these antimalware programs have however been third-party products. This trend was essentially bucked with the introduction of the Microsoft Windows Defender (formerly known as Microsoft Security Essentials in Windows 7 OS and below) into the antimalware landscape in recent times. As obtainable from the results of most tests carried out by various computer antivirus evaluation organizations, it is evident to connote that although Microsoft Windows Defender comes with a number of useful and beneficial characteristics; its overall performances are fundamentally mediocre when compared to other antivirus solutions. For instance, AV-TEST revealed that the May-Jun 2017 Real-World Testing on protection against malware attacks by Microsoft Windows Defender was merely 99% as against the industry average of 100% for the same period.
