page cannot be displayed - HELP PLEASE

[lost2005]

I am a bit of a novice at all this and as of yesterday cannot get into my bank website or any email accounts at various places :-( - all come up with page cannot be displayed.

I can only get onto one email site through the messenger service but that is for my husband only  I cannot get on at all

I have run a virus check but nothing, and have restarted the computer more than once.  Have deleted all temp files and all cookies.

We're in a very small town  so nowhere to take the computer to immediately

Any help would so be appreciated

What operating system do you have?  Have there been any changes to the computer recently?  Also do you use any anti spyware programs?  If not you should.

Some things for you to run would be:

ccleaner                         <---Cleaner
ad-aware                       <---Anti-spyware
spybot S&D                    <---Anti-spyware
microsoft antispyware   <---Anti-spyware
AVG Free                       <---Anit-virus
Ewido                            <---Anti-Trojan

You can download all of them for free.
