Okay, I recently had a virus that would not let me search the web or use my antivirus. I got rid of it but it seems to have messed somethings up. For example, I am unable to upload anything to anywhere. This includes Imageshack, Filefront, Mediafire, Photobucket, Yahoo (attachments). I am also unable to use the Steam Store and Community through the portable Steam (one installed on your computer).
It just says
Navigation to the webpage was canceled
What you can try:
Refresh the page.
That is the store page.
The community page says
This program cannot display the webpage
Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.
What you can try:
Check your Internet connection. Try visiting another website to make sure you are connected.
Retype the address.
Go back to the previous page.
More information
This problem can be caused by a variety of issues, including:
Internet connectivity has been lost.
The website is temporarily unavailable.
The Domain Name Server (DNS) is not reachable.
The Domain Name Server (DNS) does not have a listing for the website's domain.
This is not a problem with Steam, it has been going on for 2 weeks now. I can only use Steam through a browser.
My best guess is the virus tampered with the network settings in someway that it blocks something that those sites and Steam have in common but I don't know what.
