XP SP3 os with IE8 / Avast Free Antivirus 2014.9.0.2021
I received a notice from Avast asking if I wanted to 'fix' the problem caused by the out of date (but most up to date for XP) Internet Explorer (which I don't often use). I intended to look further into that when I had more time but it hasn't appeared again. What does the fix do please and how can I access details of it again?
Also regarding the Avast Firewall being offered - would I have to stop using Windows Firewall to use that?
