Persistant Popup's Whilst Browsing

[walrus222]

Over the last few weeks I keep getting warning pop ups that say I have a virus and that my Google browser needs updating especially when I'm working on my family tree. One of the offenders says "the page at DL31.11stny.com says your computer may have a virus. follow instructions to remove." Another keeps popping up with a Windows PC repair notice. Since I regularly run my antivirus program (MSE) and Malwarebytes program. I am very confident I do not have a virus. I get the messages mostly when I am trying to update my family tree in Ancestry. Any help please. Coz it's really annoying me now.
Thanks in advance.

Standard response is to suggest running MalwareBytes to check if you have been infected.
