I have suffered some problems over the last 3 days which have prevented me from accessing various websites, such as the Yahoo login page and other login pages, although not all of them (I logged onto this forum without a problem) As part of my attempt to repair the situation I tried a system restore to a point before the problem started. Unfortunatly the restore finished and reported it had been unable to complete because it couldn't access a file and suggesting that any firewall and/or anti virus applications be switched off and to try again. Which I did, several times and with the same result. Can anyone suggest the next step, please? the problem with the website access is still there, on the sites I can't access I receive the message "The server at...... is taking too long to respond" - could this be due to a weak wireless signal or connection?
