Multiple certificate problems while web broswing since this morning

[grendizer]

Whenever I visit a site I got Kaspersky messages saying the certificate isn't valid and it is advised not to visit this site. Even with LinkedIn.com ! The I can't visit the site!

There are other sites I can visit but then a lot of Kaspersky messages pop up from the systray and PART of the site is disabled so I can't fully use the website .

Is this a buggy update problem?

I also have a problem opening my own website which was alleged carrying a certificate mismatch to its own name, but I could not find which certificate authority to correct.  It always happened like no matter what I tried to do.   this website name is harmonybuddhism.org.  I tried to open it from all the browsers on other devices and found it working OK.  I checked with Kaspersky help desk who said  they don't know what has been the cause.

 

For another problem, a pop message always started when I turned on my computer, with Kaspersky on, that said "failed to initialize the Microsoft . NET Framework. Please reinstall it", and I have tried to reinstall it many times, but to no avail, even though the methods of reinstalling it are recommended by reliable sources.

 

Can Kaspersky help desk have any suggestion to help me deal with the two above problems which persist.

Kind regards
