Does downloading Flash increase issues related to viruses/trojans etc like on a windows pc with flash?
The only anti-virus you need to protect your Mac is education and common sense.
I disagree. If you're vigilant about knowing what app you're inputting your password in then you have nothing to worry about on the Mac or on any modern Windows machine. Most viruses out there today are trojans because of better security on all modern OSs.It's still a good idea to regularly use an anti-virus program, in order to prevent passing PC viruses you may have accidentally downloaded, from your mac to your PC, or a colleague/friends PC.

Also, there is no way that I'm running A/V software that will slow my system down just because there is a possibility that a colleague or friend won't think before they give apps permission to run things as root. If they're that naïve then they can bog their own system down with A/V software.
