I have a HP Pavilion with Windows 8.1 and I use Mozilla Firefox and BitDefender free antivirus.
Malware screening and general system cleanup have all been done (many thanks satchfan).
When I connect to my ISP it starts up ok, then later hangs, is slow to download or simply can't access the website.
The problem solves itself when I log off and relog on with my ISP but only temporarily.
