Mac Forum / Applications / Virtual PC / September 2005Performance Issues with Virtual PC
If you're using virtual PC for windows and you have anti-virus enabled(specificaly nortion(and I'd like to hear from Mcafee users, as I want to move to that) I disabled my anti-virus on a test box and to 200 + % performance improvements. Just fyi -- I don't recommend this for everybody, but it worked for me.  SignatureProgrammer I was fortunate enough to have McAfee Antivirus installed on my virtual machine, and I would do two things (unless you think you need them otherwise): -- put your firewall into Trusting Security mode... the less the firewall has to do to filter out packets, the better. -- disable ActiveScan. This tool monitors all reads from your virtual drive and is the main source of pathetic virtual machine performance! You may have to ask yourself... if I need to do the above, then why bother having an anti-virus product installed and running? Well, it's good for doing one-off virus scans. McAfee allows users to select a place to start scanning manually for those PC software nasties, so that's at least one good reason for having it installed. Otherwise... if you have an external hardware firewall (an AirPort basestation, for example, that uses NAT addressing) and don't care to virus-scan your system every once in a while, then there's no need to have the software installed. > If you're using virtual PC for windows and you have anti-virus > enabled(specificaly nortion(and I'd like to hear from Mcafee users, as I [quoted text clipped - 7 lines] > -- > I don't recommend this for everybody, but it worked for me. -- -- tonza If you disable ActiveScan, then you are absolutely running the risk of being infected by a virus. Sure, your antivirus program will pick it up and remove it (assuming that your virus definitions are up to date), but only AFTER the damage has been done. Why would you want to take that kind of chance? > If you disable ActiveScan, then you are absolutely running the risk of > being infected by a virus.

Right you are... but I would rather spend more time actually running the PC software I wanna run rather than some stupid anti-virus program, especially in an emulated environment!!! D'you know how much CPU time your Mac takes running a PC anti- virus program?! Way too much!!! So, this is what I do: take the PC off-line. End of story. And only plonk the PC back on-line after I have Undo Drives active for the time I need it. That way, when virus does hit, I can LAUGH at it! Signature-- tonza. I understand what you're saying....but I don't understand whay anyone would want to allow a virus on their system when you can prevent it. I think that the problem you have with antivirus software is that you're using one that has way too much overhead. Try this: uninstall McAfee download and install AVG.....update the definitions You will be very pleasantly surprised to find that there is very very little CPU usage. |
