It's not necessarily a bad idea but it also depends on how far they take it. If CD servers were compromised and ended up on such a list the problems start on how it's handled. A null DNS entry gives you "server not found" error, if they were redirecting it to "this site has been compromised" that would be helpful.
The next issue is false positives and getting a site removed from a list. I had a major virus vendor flagging content on my site as malicious. This was free service offered through a major ISP. Trying to get it resolved proved to be a major hassle. The anti-virus vendor tells me it's the ISP's problem and the ISP is telling me to contact the anti-virus vendor.

If I had a nickel for every time I've had two vendors blaming each other for their own shortfalls, I'd be retired by now!
Absolutely a good idea. I never use my ISP's DNS server. I configured the job to, as well. We use Google's DNS (but I do have our ISP listed as a backup *full disclaimer*).
With satellite internet, you are forced to use the ISP DNS. It has to do with the way stuff is encoded at the NOC to conserve bandwidth, from what I was told. Even if you set up an alternative DNS, it just reverts back to the ISP one.
Changing computer DNS settings can help stop malware?
I think the key is the word "help". There are a lot of things people can do. But none of it by themselves will do everything. And doing everything will still not get you 100% security. The best you can do is get it to a point where you are willing to accept the residual risk that remains.
The main thing to understand here is that the foundation that the Web/Internet was built on was not initially designed with a lot of security in mind. So folks are now going back and enhancing it piece by piece. Of course, you are also then relying on those that support the infrastructure to actually implement the enhancements.
