Frequent kernel panics osx 10.9

Avast is possibly the worst Antivirus software available for OSX. Uninstall it, and its associated drivers, according to the developer's instructions. If the uninstaller still leaves traces of the software on the machine, then you need to manually unload and then delete the kernel extensions.

Additionally, you have made other low level system modifications which may be a catalyst. If the panics continue, uninstall the software associated with each driver in descending order until they cease.

Most often, kernel panics are caused by third party kernel extensions which are either deprecated or incompatible. In order to resolve them, these extensions must be removed.

Regardless of Messages being identified as a possible suspect, I find that highly unlikely, as that is Apple software running on Apple hardware. I'd be willing to bet that it is your Avast software, which should only be necessary if you often use the machine in a Windows network with Windows users. Avast on OS X really has no benefit to the Mac user, and only helps protect other platforms from Windows viruses that may have entered into your own files. Surprisingly, Avast includes an uninstaller with their installer, if you'd like to remove it to see if the kernel panics cease.
