DNS Changed - by what?

Hi,

On working with my PC after some problems with video, by chance I
looked at the DNS set up. Thes IP addresses were completely different
to what I would normally have used. Is it the case that there is
"malware" etc. that can adjust these without your knowledge? What I
found weird is the two DNS IPs are in completely different ranges.

TIA

I've never heard of it, but it is certainly possible. What were they changed
to?

Normally, they should be in different ranges to increase redundancy.

Did you set up your PC's DNS set up manually, or does it get its DNS from an
ISP dynamically? If the latter then it is probably OK. If it was set up
manually then it might be cause for concern as I have heard of malware
hijacking DNS entries and pointing your PC off to their own sites.

Are you on broadband or dialup? If Broadband is a USB interface or a router?

Normally set up manually.

Broadband, router.

As per my other reply, the assigned IP addresses for the DNS are ones
that I would not use or even know of. I usually set them to addresses
used by my ISP's DNS.

I'd be suspicious that the rogue DNS servers will try to route web
traffic through a proxy that will scan it for passswords and personal
details.
