Hi, Phil.
Usually, AVG does not interfere with web based emails. Please share a screenshot ( http://avgclick.me/getscreenshot ) of the exact error message if you receive any when you try to send or compose emails with AVG enabled.
OK, in the last few days I have been unable to SEND emails from my Hotmail account using Firefox (59.0.3) on Win 7 with AVG Free.
Even worse on IE as I cant even compose email!
Incoming email is fine
I tried disabling firewall, no effect but disabling AVG means I can once again send email.
Anyone found the same and got a fix / workround?
Solved it by unistalling AVG and reinstalling it!
Seems to be the defacto answer to problems with AVG.
Phill, I am glad to hear that reinstalling AVG has been fixed the issue. However, as informed in my previous message, AVG does not scan emails if they are being exchanged using a web browser. AVG will scan only emails received and sent via an email client like Outlook.
Please monitor the situation further and let us know if the issue recurs.
Thanks all, will come back if the problem reappears.
