Network not working, domain unreachable

Problem: Internet is working, but computer browsing is not

Apart from varios viruses, SNACNP Network Provider was active.
It can be seen and unchecked via Autoruns, by Sysinternals.

After uncheck, repairing IP should renew address and make it work.

Thanks to Zac.
