    If you get a screen that looks like this:
    It's called a kernel panic. If it doesn't happen again, or very infrequently, you don't need to worry about it.
    If it does happen again, this may help:

    You need to look at the console log and post it here. There are people who can make suggestions from looking at the console log.

    Uninstall your avast! virus protection software. It appears to be the culprit, and you don't need anti-virus software anyway.

    I recommend that you avoid using Sophos, as it could actually increase your Mac's vulnerability, as described here and here.

    Mac OS X has built-in anti-malware protection. That, combined with practicing safe computing, is all you need to keep a Mac malware-free. For details:

    Last and only time I had a kernel panic was when the cpu fan quit working in my 2008 Macbook. YMMV of course. But I know a few mac owners who've been all mac as long as I who've never had a kernel panic.

    so do you think that avast antivirus have also a virus or malware in the setup planted?

    No offense, but the notion that Macs do not need antivirus apps and have "built-in" malware protection is exactly the type of egotism that will compromise your information.

    I thought the same thing, until someone tried ordering airplane tickets to China on my credit card a few years back. I didn't get the picture, I thought I entered my CC info into the wrong website. Then my WoW account got hacked. A family member of mine had a Norton subscription so I downloaded it from them, ran it, and it found malware. If you spend most of your day at your computer like I do then eventually you are going to install something stupid. In my case maybe a DRM removing app, video encoder, or who knows?

    Macs get viruses -- don't be completely ridiculous.
  15. GGJstudios macrumors Westmere


    May 16, 2008
    It's not egotism. It's a fact that practicing safe computing as described in the FAQ posted earlier will fully protect your Mac against every form of Mac OS X malware that has ever been released in the wild. 3rd party antivirus apps offer absolutely no protection that safe computing and the built-in anti-malware don't already provide.
    Giving your information to a phishing site has nothing whatsoever to do with malware.
    What malware, exactly? It was most likely Windows malware, which has no effect on Mac OS X.
    One of the primary rules of safe computing is not to install software from unknown/untrusted sources. No antivirus can protect against user stupidity.
    Name one.

    and yet i still don't really know if Mac needs antivirus or not, and where do you know this that Mac has a in-built- anti malware and antivirus ?
    the one said yes mac needs antivirus, the other one said not necessary at all ....????

    Apple themselves push the cures to the known bits of malware via Software Update. This isn't opinion, it's fact.

    I've used this analogy elsewhere:
    Installing an antivirus program on a Mac is a lot like wearing full plate mail to a gun fight. It's not going to protect you against bullets any more than your street clothes are, it will probably even slow you down, and yet since you feel "protected" you're likely to get overconfident and run out and do something stupid.

    oke i read it and this is very clear about security, indeed mac have a built-in anti-malware protection so its not needed to install another anti malware program for mac .....

    I did not give my information to a phishing site.

    I implied that I had some type of keylogger or spyware virus, which was how my CC and WoW login were compromised.

    Half the applications I open ask if I'm "sure you want to open this application [from the internet]?" I'm sure it is the same for most people. It is a BS disclaimer, common to both Windows and Mac OS since 2007, which means absolutely nothing and provides no protection in itself. It is ultimately up to the user's judgment what he/she considers a reliable app to install, and if you are installing multiple apps per week or day then the laws of probability are against you.

    Mac OS was unable to prevent my getting a virus nor detect it when these incidents occurred around 2009-2010, and the results could have been much worse than they were. That is a fact.

    "You DO NOT have a virus on your Mac!" is not a fact, it is post designed to shut up people who repost "do you think I have a virus??" Also, it is irrational Mac fan garbage aimed at categorizing an entire group of people who have been infected with malware, partly as a result of listening to ridiculous "facts" such as yours, as stupid.

    It is possible that in my case the spyware made its way into my OS before Snow Leopard came out, then the information it retrieved was used months later. It was still Norton which eliminated malware (I assume the spyware in question) from my OS, even after Snow Leopard was installed. I am just saying exactly what happened.

    There are no keylogger or spyware viruses in the wild that can infect Mac OS X. The only keyloggers that run on Mac OS X require the user to actively install them. Read the FAQ I posted to understand the difference between a virus and a trojan.
    That warning is not the anti-malware I referred to that is built into Mac OS X since Snow Leopard. Read the link I posted.
    You can safely install as many apps as you like, as long as you're not foolish enough to get them from unknown/untrusted sources such as pirated software sites.
    You did not get a virus on Mac OS X. Period. There are none.
    Name one Mac OS X virus in the wild. Just one. I'll save you some time: there are none. The only Mac OS X malware in the wild is in the form of trojans, which can be avoided by practicing safe computing as described in the Mac Virus/Malware FAQ.
    A virus is only one form of malware. There is nothing in my posts or in the FAQ that suggests that there is no Mac malware in the wild. Understand the difference.
