Avast prevents System Update from working:

Linc, you of all people should know the hazards of taking a few scattered reports here too seriously. Especially given the poor quality of information. The first link you posted involved someone who had both Avast and Kaspersky installed, and who continued to have problems after Avast was removed. In the third, you simply posted your opinion, which was never confirmed or denied by the OP. In the fourth one, the OP removed more than one program at once, so the culprit is not known.

This is not quality data. I'm actually disappointed that you would resort to such.

As for your snide remarks about my memory, I would like to draw your attention to the date on those comments of mine that you refer to. At that time, I was commenting based on a handful of scattered reports here. Since that time, I have performed not one but two tests of Mac anti-virus software that included Avast. I now restrict my comments on Avast to what I know, rather than what I think I know.

No, Thomas. I've tried at least once that I can recall to explain to you how to read a kernel panic. I'm not going to repeat the exercise.

How do you explain how the rest of us who run programs you don't seem to trust don't experience any kernel panics or other "known" issues as you put them. Let me take a stab at it... are you going to use that line "you think you don't have any problem, but you actually do"? :rolleyes:

No, you've never tried to explain anything to me in that regard. You have told me I don't know how, and criticized me for it. That's what you do - you tell people things, and if they disagree with you, they are simply wrong.

In this case, it does not take amazing talents at reading kernel panic logs to tell that your data is sparse and not even remotely conclusive. But at this point, I think we should simply leave it to the reader to decide whether to trust someone who has done some testing with the product in question or someone who has never even used it.

Thomas, here's a thread that shows the expertise that's needed to properly read a Kernel Panic and suggest a fix. https://discussions.apple.com/thread/4897194?tstart=120

Obviously I'm being facetious with this, but you get the idea. There's no magic to it. Usually something within the dump points to the issue app or system component that could have caused it. Generally speaking it's the first one listed. Take care of that one and test again. If it dumps again, you see what module and/or app is indicated next. It's not that hard to do really. If a graphic designer can do you, so can you. 😉

Sorry for the hijack of this thread to show you this, wish this site had some PM options, but it doesn't seem to.

I actually know how to read a kernel panic log just fine... Just not up to Linc's standards, as he has repeatedly told me.
