It may be noted that immaterial of fact any browser is on or not, if firefox is installed on system, at 1900 hrs, "windows defender club" site opens. I uninstalled firefox and problem did not surface whereas I have Chrome and Edge browser installed. If there is no solution, i will permanently uninstall firefox.

Hello skagrawal,

Unfortunately you've picked up some malware, that you will of course want to get rid of.

Would you please go to the 3-bar menu => Add-ons => Extensions - if you see anything there that you didn't install yourself : please remove it.

Then do the same in Windows Control Panel => All Programs

Next step will be to run all malware scans that are listed in this article :

(what one doesn't pick up, the other one might)
