Redirect from half of the sites to mobi-co.in

Question

Malware

Hey!
I just opened my laptop and half of the sites are redirecting me to " mobi-co.in/land.php?s=5208&a=b&l=&auto=6 "
Google DNS.
On other computers on the network everything is ok.
Redirect only in Firefox and Chrome (Opera and Safari - ok).
System: Mac OS X Mountain Lion.
It looks like a virus on the computer. What to do?

Answer 1

The problem was in the DNS.
For some reason, the standard Google 8.8.8.8 and 8.8.4.4 were disabled, and while I was visiting clients with a laptop, someone changed the IP address of the "google-analytics.com" domain.
It sent me the modified ga.js.
Cleared DNS cache and browser cache.
I only wonder where I could run into an infected router today.

Answer 2

As far as one can judge from other messages on the Internet about a redirect to the specified site, this is not about a local virus on the device (by the way, these symptoms also occurred on mobile devices with Android and iOS), but about “viruses” on the sites that you visited (which are registered in .htaccess and redirect certain traffic to the specified site), or problems in the network itself.
It is worth looking at a specific set of sites that carry out redirects - perhaps they are infected or have been infected in the past, in any case, it is also worth clearing caches and cookies in browsers. It is also possible that the problem is in the network itself, here the different behavior of several computers is not always a reliable indicator.

Answer 3

But what about "There are no viruses on Mac OS"? :)

Answer 4

hosts looked?
