I can't pinpoint what is your antivirus? you probably need to fiddle with its settings particularly if there's a browser category. If you have your AVs browser extension, check it too.
But are you sure it's from your AV? just checking, as other programs can also give similar warnings.
I am using avast and no browser extensions installed so I am pretty sure it antivirus was blocking me. False positive that's what I thought and even when I tried to ignore the warning still there is another new warning popped up. I have to check in the setting again to make sure it doesn't happen.
