It is my wish to be as helpful as possible to you. Unfortunately, I am unable to find out anything about Mitsubishiconfit.com and, as you now have it also on your Kindle, I must assume that it has been downloaded from a site which you use regularly and have had to register to access the site as a member.
The item is unlikely to be a a virus which I feel sure would have been observed by Kasperksy, but is some form of Malware. Consequently I suggest that you download and run a scan with the free edition of Malwarebytes, and report back in this thread. Do Not accept any trial of the Pro version which is unnecessary for Home Computers.:-
