You should check your computer for one of those sneaky DNS Changer malwares that modify system in order to redirect most of the victim’s traffic to the services attacker needs. The one we are talking about, Rove, has managed to infect around four millions of computers since the beginning of 2008. With its help, scammers get unlimited power over the compromised machine – they can replace download requests for a certain software, reorder search results and even exchange the ads that are displayed to you.
Rove is closely connected to Google redirect problem that has been actively bothering users wold wide in the end of last year. Even if you don’t suffer from redirections when browsing the web, it’s really dangerous having this malware on your computer – the moment when these servers will be shutdown and DNS stops working, infected users will lose their Internet connections and receive ‘The address is not valid’ on their screen.
If you also suspect you are infected with Rove, you need to reset the DNS servers that you use. Click on Start, Control Panel, Network Connections, then click right on the icon identifying your connection and select ‘Properties’. Additionally, select Internet Protocol (TCP/IP) and click on the ‘Properties’ button. This will show you the screen where the DNS servers are set. Here you should select ‘Obtain DNS server address automatically’ and then press ‘OK’ and Close. In addition, run a full system scan with updated anti-spyware program to make sure your computer is completely safe.
