Use an ad blocker, but do be aware that using an ad blocker will not eliminate ads over time. Changes adware developers make, changes to website software, changes to browsers, etc, mean that it is a never-ending arms race between us users and the adware developers. As soon as one is blocked, another one will take its place.
The same goes for anti-virus applications. You will never completely eliminate viruses and malware, you will only reduce the chances that you will fall victim.
Prost!
