Do i need anti virus software with vmware

Your Windows 7 session will not be "virus proof" if you are relying on the mac for the root of it's security.

If you expose your Windows 7 session to a virus or malware and are not running AV you will likely be infected on the Windows "side" but it will not affect your Mac

Windows 7 will remind you if you don't have AV but you can shut that warning off if you feel obliged.

On your mac it's the consensus around here to avoid Mac AV solutions, they tend to cause more problems then they fix and they are not as flexible as they are on their windows counterparts.

Whatever runs on VMWare is separate to your OSx. If you are getting Mcafee ads on OSx, then you likely have some type of Mcafee extension installed on your Mac producing them and would have nothing to do with Windows or VMware. If you are getting them only inside the Windows Virtual Machine, then you have adware on your windows virtual pc.

Windows on VMWare is susceptible to the same viruses that a windows computer would be as well. so an antivirus for windows would be required.

However, windows viruses would not be able to affect your Mac, and would not be able to get out of the Virtual machine that is running windows anyway.

The only place that you install anti-virus software is into Windows 7 running inside of that VMWare guest container. People that install anti-virus into OS X wind up posting here wondering why their Mac is running slow, hangs, and reports false viruses and malware. OS X already has a robust security environment that the addition of anti-virus software will very definitely cause interference.

if your not running AV in windows and if the Macafee is warning you in Windows I don't think it's Macafee - do you have a scam pop-up somewhere on your screen?
