"Your computer restarted because there was a problem"

Over the last week or so, I've had issues with my system suddenly restarting. I have not been able to conclude any common symptoms when this happens and this issue is becoming more and more common to the point where it is happening multiple times within the hour, making my Macbook almost unusable.

Anywho, I did a litte reesarch and found out about Panic Reports, and did a little more digging around and found that theres a way to interpret these... I have looked through the report and I 'think' that the random restarts have been casued by Kaspersky.

The logic behind this choice is from the following taken from the report:

>BSD process name corresponding to current thread: kav (kav = Kaspersky Anti-Virus?)

>Kernel Extensions in backtrace: com.kaspersky.kext.kimul.42(42.0)[658C1759-7925-7346-A10D-B468C1BD7A1D]@0xfffff f7f8a0fc000->0xffffff7f8a105fff

Unfortunately, this is as far as I have got - and can't really figure the rest of the report.

I have now uninstalled Kaspersky (using the official uninstaller), and so far my Macbook has been fine, however this could indeed just be coincidental.

Off tpoic and on a side note, I finally made the jump to Macs about 9 months ago and broought with me the PC Mentality and as such installed Kaspersky, you know, just to be safe. I appreciate that "Viruses" don't actually pose a threat to a Mac system, but with previous threats like 'Flashback' and the newly found threat 'Dockster' (http://news.cnet.com/8301-1009_3-57556939-83/new-mac-malware-spreading-from-dala i-lama-tribute-site/) - albeit using the same exploit as Flashback - I find it difficult not to have some form of protection for my Macbook.

So, back on topic, was Kaspersky the likely cause of the random retstarting issues, or was something more serious and/or sinister happening?
