Me pooters broke!!!!

Last friday when I first logged on the AVAST box came up and wanted to do a scan. I went with it. Immediately following that I was unable to sign into my Ebay account. Basically I haven't had a mobile number since 2016 but my old one was still on their records. When the verification box came up I used to click on e-mail so a code would be sent, which I filled in and all was well. However, the email option didn't come up so I filled in my password, and clicked on "Need help signing in". This achieved an e-mal option but despite receiving said e-mail code and the problem persisted. I filled in the code, but  the reply said that I had signed in successfully.......... "Click to continue shopping" when I did that it took me back through the sign in proceedure. This went on indefinately.

After 4 days spending 2-3 hours per day on the "Chat" service, I ended up closing my account.

This morning exactly the same thing happened.......... First box was Avast, but despite closing it immediately I then found that google was asking me to sign in. That has never happened before. It seemed they wanted to verify I was over 18........... same problem with the lack of mobile phone.

Now here's the thing, I usually use Avast secure browser, so I decided to try Internet Explorer and using that I got to google no problem.

I've uninstalled Avast premium cleanup, but should I also get rid of the browser?

Also what browser is recommended these days?
