He's right actually. AntiVirus takes up a lot of processing power, particularly with things like video and games.
Before dual core processors, about 40% of your processing power was going towards Windows' built in real-time scanning provisions. Windows compensates for this in the task manager so you don't notice any difference (other than a loss of performance).
Wow, it's amazing what kind of crap people will believe!
That statement could not even be farther from the truth.
IF you have anti-virus (and you don't need it as long as you don't visit shady sites or run suspicious software), real-time scanning would add an extra 1-2% of CPU time for opening that file. The only time you have any REAL performance loss is when you do a full drive scan.
Seriously, this kind of stuff is pure FUD. It's absolutely untrue and when Mac fans use it as an argument against Windows, it makes ALL of us who own Macs look like fools. So quit with this nonsense so those of us who do have common sense do not look as foolish as those who fall for these kinds of lies.
You show your ignorance. A properly configured anti-malware program will scan all things real-time, including files, web pages, etc. Just because today's CPUs are blazing does not mean they don't get wasted on things like this. Calling me a "fanboy" does not change the truth.
I should also add that I don't know that it takes up that much processing power, but the fact is, it takes some processing power. Watch a program like Avast constantly scan as you're simply surfing the web. You may never notice the hit on a current processor (solo, duo, or quad), but the small hit is there. So yes, the same processor in a Mac will be slightly more "efficient," since none of its threads are wasted scanning every little thing you do.
Actually, you show your ignorance. I run Windows on my HP and Mac without any anti-virus or anti-spyware software. How do I get along safe? Well, I don't visit shady websites and I don't install any software. IE7 and FF warn me about any software that wants to install and I can choose whether or not to install it. But the great thing is, I don't visit any sites that would be potentially harmful (why would I visit those sites anyway?) so I don't even have to begin to worry about these kinds of things. Outlook in XP and Windows Mail in Vista do NOT autorun attachments, plus most people use webmail these days and Gmail, Yahoo, Hotmail, etc. all do virus scanning on the fly.
So as long as you don't do anything that you probably shouldn't be to begin with, you'll be just fine.
Also, run benchmark on the computers. Same computer, same processors, same ram, same harddrive, running windows xp scored only 85% as the running under OS X. [geekbench]
Is there any other proof besides one synthetic benchmark? Because I see software like Handbrake, DVD playing apps, and games ALL running faster on my Santa Rosa based 2GHz Core 2 Duo than they run on my 2.16GHz MacBook. Obviously the games run faster for other reasons
Windows Media Center is dying an early death. It is actually a very good media center and the only reason that it eats Apple's Front Row for lunch because it's been out for 3 years ahead of Front Row, It should be better but as I said with the invention of AppleTV, TIVO and even the Xbox, WMC is dying an early death, nobody uses it, it's just a novelty. Your point is moot.
rofl, nobody uses Windows Media Center? You can't be serious with that ridiculous comment. Head over to AVS. Theres about half a million people there who disagree with you. Most people use Windows Media Center, especially with Vista. WMC makes it easy to pop a TV tuner in and be up and recording TV from any source, satellite and digital cable included, in a matter of minutes.
Windows Media Center is far more capable, and much better looking, than Front Row ever is and ever will be.
For those with notebooks, especially those sold within the last year, they can pop in an ExpressCard TV tuner, record their favorite TV shows either in high def from over the air signals or from their DirecTV or cable box, and they can simply plug an HDMI cable into their notebook and hook it up to their HDTV.
Windows Media Center also makes it easy to stream media to your Xbox360. Recorded TV, etc all get streamed easier.
Media Center is here to stay and offers much more functionality and (in the case of DVD and HD DVD/blu-ray playback) much more quality.
