Banner Ads on my email and disappearing app

Suddenly, tonight when I switched on the computer, my email had a big ad banner (AdChoices) at the top of it which could not be removed. I am not very expert, but searched the web and found a recommendation to run adwcleaner in safe mode, which I did, but when it rebooted again, it was still there. Same after running a Malwarebytes scan.

Then, I tried to open a file in Kingsoft Office, which I had been looking at minutes earlier, and I was told that Kingsoft Office was no longer on my computer, and the shortcuts at the bottom of the screen were greyed out and did not work.

Can someone please help before more things go wrong.....?
