After launching Windows 8/8.1/10, Microsoft eventually upgraded their built-in antivirus capability to detect malwares and spywares with improved Windows Defender tool.
Sadly Windows 7 users have to install third-party antivirus tools to keep their system safe. And Microsoft always recommends to install their antivirus — Microsoft Security Essentials.
Compared to Windows 10, Windows 7 still has the market share of the top operating systems in use — about 47% of people still use Windows 7 and majority of them had installed Microsoft Security Essential as their antivirus tool.
And according to the German security firm AV-Test, Microsoft Security Essentials is one of the worst antiviruses out there. AV-Test carried out a series of tests in Windows 7 with different antivirus tools and find out that Microsoft Antivirus is the worst performing antivirus along with Comodo’s.
AV-TEST says Microsoft’s security solution was worth just 13.5 points, while Comodo was once again at the bottom of the pack with only 12.5 points.
Microsoft Antivirus was rewarded with 5 points for protection, 4.5 points for performance and 4 points for usability. According to test results, Microsoft Antivirus can effect substantially in your system performance and it could also dramatically slow down a Windows 7 system.
The tests were performed in July and August, and Kaspersky’s antivirus products got the maximum 18 points, with 6 points for each stage, namely protection, performance, and usability.
