My main computer can no longer get online. It was fine yesterday (and had been for years)
OS Windows Vista Business Service Pack 2
When I start Chrome the initial screen comes up almost blank, there are tabs and "google.co.uk" is shown in the address bar and the phrase "This webpage is not available" is shown in a box with a "Reload" button and a "Details" button. If I press the Details button it says
"The connection to google.co.uk was interupted.
Check your internet connection
Check any cables and reboot any routers, modems, or other network devices you may be using
Allow Chrome to access the network in your firewall or antivirus settings.
If it is already listed as a program allowed to access the network, try removing it from the list and adding it again.
If you use a proxy server...
Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server: Go to the Chrome menu > Settings > Show advanced settings... > Change proxy settings... > LAN Settings and deselect "Use a proxy serverfor your LAN".
Error Code: ERR_CONNECTION_RESET"
When I start FireFox It looks fine first of all but when I type in a search term I get a box that says "The Connection was reset..." etc
Odd thing I noticed when first turning on was that the small image of 2 x computers in the bottom right which normally shows just the computers when turned on (then it includes a globe when an internet connection is established) showed a yellow warning triangle before going to the globe .. it doesn't normally do this.
Yesterday I downloaded a copy of Open Office, before that I had tried to download a "free" copy of PowerPoint (I thought it was legit !) but it hadn't worked as far as I could tell wasn't in my downlaod folder.
I have run Malwarebytes which found and quarantined several files, including a trojan. I still couldn't get online, I then scanned with Sophos, which found 2 x other malicious files, but I still can't get online, I am currently scanning with Malwarebytes once more, but don't hold out much hope.
