Did you know someone can change the setting on your router so all your internet traffic goes through their servers and from this they can get your bank details as well as other personal information?
Routers come with a standard password and I usually use this to access clients routers without even asking if they know the password. This is because the router is usually the last place someone thinks of needing a password or they simply have not known it. Now, well for some time, criminals have taken advantage of it, they have developed malicious code to change your setting on the router.
This looks like the computer is affected by a virus but even after a computer has been cleared of everything it still has the same error and all computers will show the same symptoms. You may net even get any symptoms which makes it worse.
When you go to a website your computer does not know where that website is hosted so it looks for a DNS server. On nearly all home routers this will be set to get the address of these servers from your ISP automatically. So when you type in a website address it goes to these servers and they look up where the website is, return this information to your computer and you get the website displayed on your computer. This virus changes the settings so it does not get the DNS server of your ISP but theirs so they can see what you are doing and intercept any data they can.

How do you change this password? If you are confident then search for your routers model number and for the instructions. This should tell you what to do, if you are not sure then get a technician in to do it for you. It does not take long and you will know that this virus can not affect you.
