... or, well, they try to. Both Firefox and Chrome now blacklist almost all antivirus scanners from running in the (sandboxed, security-sensitive) contexts in which the actual content of the webpage is accessible, because they are generally written by absolute monkeys on the assumption that they are *not* sandboxed, and as a result have a distressing tendency to call out to things prohibited within the sandbox (a list which is always growing, for good reasons) and get killed. And when this happens it leads to *every single webpage* turning into a sad-face crash, often after a browser update improves the sandbox.
The difference between virus scanners and rootkits and malware is basically just intent, these days. Virus scanners use a very large proportion of the techniques used by rootkits, and unsurprisingly things that actually want to be secure tend to react to virus scanners as if they were malware.
