Few days ago, Google declared that it will start informing users of its google about possible attacks of viruses or trojan’s on their devices. Originally the effort will be targeted on the DNSChanger virus, but hopefully it will be prolonged to other viruses.
DNSChanger is a Windows-based virus which changes the computer’s windows registry containing the nameservers your computer uses to find websites. As a result you will type something on the web browser and will be refocus to another website, possibly containing further viruses.
In order to be informed about a possible disease all you need to do is to find on Google.com. Here is how the cautions looks like:
If you are thinking why they never this more often, here is why, according to a Google protection engineer:
“In common we want to inform users [of viruses infections] at any time we are able of doing so, but the truth that we never do this more often is really just because it’s difficult to come across situations where we can do it perfectly. In many situations we only have maybe a 90 % assurance that someone is contaminated, and the bogus good amount of 10 % is basically too great to be possible. But in this situation we can be basically certain that someone is contaminated.”
