Hey, I don't know the guy nor the website. I don't randomly trust websites. It's like Tom's Hardware who people keep referencing but that website has shown bias, nonobjectivity and unprofessional attitude for the past 10 years.
If you want, let's look at the details of that review then. I'd rather look at it than just toss it aside.
Application launch? So MSE adds 0.063 seconds to launch time compared to NOT having an AV program. That's what most people do all day, and that seems to be a very intrusive number.
Boot time? MSE supposedly adds 10 seconds to boot time. That's debatable. I'd like to test it out in a VM and get back to you.
Note
I tested this out in a VM running a fully patched Windows XP SP3. It is set to use 512MB memory and uses 2 virtual processors from my 3.2GHz Core 2 Quad. Boot time with MSE is 23.506 seconds. Boot time without any AV is 22.105 seconds. Raymond is quite wrong on his results.
Install 3rd party software? He used .NET Framework 4.0 as this 3rd party software. My question? WHY? Nobody installs that separately. It's installed through Windows Update. No normal person really cares about it. Bad example of software to use IMO.
Most people install software off of a CD/DVD. So it would be better to grab something off of that instead. Of course installation would be so slow it wouldn't matter anyway. But that's the most common type of application installation method.
Compress/extract file? 7-Zip, amazing program and I use it myself. I find these results debatable. He claims a number of folders but doesn't indicate their file size or whether they contain large or small files. It takes longer to compress high numbers of small files as opposed to a smaller number of large files. Some files also compress better and some files aren't even scanned by an AV program by nature of their file format.
Load website? People sure do browse the web but nobody loads 50 websites at a time. Unrealistic test really.
Game score? An AV program will not effect framerates. He used a synthetic benchmark of a 3D engine that no game uses. Bad testing example.
So what in there, other than boot time,
shows proves that MSE is an intrusive AV program?
I have never once HEARD of ANYONE saying that MSE is slowing their computer down.
