I am having trouble opening webpages. Other programs on my computer can access the internet (windows update, frontpage) and my network icon says I am online, but whenever I try to use IE or Firefox, I get the dreaded "page cannot be displayed". This was not a problem before I installed McAfee. I would really, truly apprecite any advice! Thanks!
Please check whether Internet explorer is been blocked under the firewall permission.
Double-click the M icon in your taskbar.
Select Internet & Network, then click Configure on the right.
In the section titled Firewall protection is enabled, click Advanced.
Select Program Permissions from the Home list on the left.
In the list generated , checked whether internet explorer says "Full Access" , if not set it to full access.
And then check whether you are able to go online ?
