Thanks.
First things first please.
I have Avast Pro antivirus & it is activated. Does this mean I have Firewall of any description please? I presume there are moderators or contributors from Avast (company) on this forum & so I think this question should be quite easily addressed? There is nothing under my Avast to tell me whether I am running a Firewall or not.
The most recent eruption of adnxs occurred in tandem with the unrequested appearance of a bing page, so I have uninstalled Bing from my system completely, and set Chrome as the default browser. Several months ago I was advised to set all my browsers to Internet Explorer to safeguard me from browser hijackers.
Have also shown 'Java' the door, any thoughts on this please?
Thanks again.
