Safari 12.1.1 stops downloading pages after 4-5 web sites

Wilco. Tried the new admin account. Same thing happened. When I relogged into the computer to do some work, I was editing a MS Word for MAC document version 16.25 (19051201). When I logged into Safari to email the file, Safari hung up again. Same situation but this time no previous web pages at all. I restarted the computer and now I'm in this site sending this post. I will try the Safe Mode option in little while. But the admin account changed nothing.

Tried Safe Mode again. Now I've gone through 20 web page downloads with the only odd behavior being that the Tab menus are altered colors. They are grey with black highlight that adds the "close X box" on the tab with mouse over. The Black highlights blinks and changes shape slightly with mouse over also.

When i click on the "remove" adware button, i can't find the adware files any longer. I deleted them in the trash. But the recheck finds one of them. I'll try Safari browsing to see if this is now fixed.

Tried Safe Mode. No success. Tried to relog in after Safe Mode to post - post would not go either. 3rd restart successful now.

No anti-virus that I know of. Now with reboot - back to Safari hang ups. Etrecheck says I have adware and unsigned files. Will follow this with the download.

Been browsing without issues now. Looks like the adware files were the culprit. Will ad further info it it recurs. Thanks.
