Safe site flagged as phishing

[Tim92]

A site I regularly use for work has been flagged as a phishing site. This is only happening on one of my devices and is totally fine on my phone and laptop.  It doesn't appear to be affecting any other users either.

I updated Avast to see if that solved it but to no avail. I've added it to the exceptions list which allows me to access it but I get the phishing warning as I navigate the page. I'm pretty sure it's safe as no one else is having issues.

Any ideas?   Thanks

Update: I've removed the Avast browser extension and that has stopped the constant warnings.

Still wondering why it's being flagged as a phishing site though.
