Last night I deleted some files (that I thought I don't need or use) from the control panel. I thought it might speed up my connection a bit but now I cant access anything that I need to log into ie banking or facebook or ebay. Can anyone help ??
Line speed is often the key. If you are in a cabled area (Virgin Media) then that is probably going to give you the fastest connection.
Is speed important though? I've recently dropped speed by changing from fixed-line to mobile. Mumsnet is still fine. Reduced speed affects things like BBC Iplayer, which still works occasionally but does pause to rebuffer video quite often.
www.ccleaner.com software can help clear up your machine. BUT it will also delete cookies, used to store passwords. So you need to look at the options before using it. Suggest you get someone IT knowledgeable to configure it for you.
