Kaspersky recently accused Microsoft of unfair practices for the way it deletes the company’s antivirus during Windows updates. The Russian company has now filed a number of regulatory complaints to right what it sees as a tremendous wrong. Read More I would be annoyed if Microsoft to disable/delete my third-party antivirus program, and other programs during a Windows Update. In a way, a computer maybe more safe by not running Windows Update if the reports are true that Windows is deleting Kaspersky Antivirus. Deleting antivirus can cause a computer to be more at risk at getting infected by malware like a virus, ransomware, spyware, adware, and other bad programs, and hackers since a lot of antivirus also comes with antimalware, antiransomware, antispyware, and firewall programs built-in to protect computers from malware, and hackers. I wonder could Microsoft be held responsible if Windows Updates delete a users antivirus, and other security software like Firewall which causes their PC to be more likely to be infected by a virus, or hacked by a hacker.
