There's some new malware floating around -- a variant of Trojan.ZLob --which asks you to install a new codec to see some videos... but what it really does is change your router settings so that all of your internet traffic gets routed thru their servers before going to its final destination.
If there is more than one computer behind the router, each machine will have its traffic redirected.
The malware attempts to use the default username and password of common routers to change its settings.
It's easy to change the default username and/or password of your router. Take a few moments and protect yourself.
