Chrome and Safari trying to open new page
Whenever I click on a new link - both Chrome and Safari now tries to open a page and then quickly closes it.
Even if I refresh the page, a new page is quickly open (now specific webpage) and then it is quickly closed...
The whole page will be refreshed...
It behaves the same way in incognito mode, too..
It's driving me crazy. - Have I got a malware?
Please help!
iMac, iOS 11.2.6, Google Chrome and Safari
