What is the effect it has on system? It might end up crashing your system or failure to boot. How can I prevent it?

I enjoyed reading the ideas! Many thanks to the author for sharing… And the programmer who wrote it! As a reformed Windoze user, I saw lots of allegedly funny replications of various Windoze error messages. Same here. First of all, not every virus is designed to do cause damage… some are just pranks as well. That being said… this app CAN cause problems! We all know needlessly restarting your computer with the power button can lead to undesirable results.

Virus software The category of virus software has emerged as one of the more problematic with regard to kernel panics. In particular, use of "automatic scanning" or "background scanning" functions -- which scan every new file created or saved -- has proven a consistent cause of various ills, including kernel panics.
Your best bet -- if you are experiencing repeated kernel panics related to virus software -- is to disable automatic scanning and check for persistence of the issue. Virtual PC, for instance, has been known to cause kernel panics soluble through deletion of emulated devices.
Extended or bandwidth-intensive disk transfers initiated by applications -- such as long file copies or disk maintenance -- can also be the cause of kernel panics. Try to make a note of whether or not there is any correlation between heavy disk activity and your panics, then seek out firmware, connection or directory damage issues. Once you've found the culprit, your best bet is to replace it by copying from another healthy Mac OS X system, extracting it with Pacifist , or by simply re-installing the latest Mac OS X combo updater or performing an Archive and Install.
Post-update panics Kernel panics can sometimes start occurring after an incremental Mac OS X update, Security Update or other major system modification. If this is the case, reversion to a previous system state can often resolve the issue. Pre-shutdown routines can prevent issues at next startup As touched upon above in the "Bad Network Connections" section, terminating certain services -- including Network services, Bluetooth connections, sharing services, and more -- at the time of shutdown or before putting a system to sleep can prevent kernel panics that occur at the next system startup or wake from sleep.
Simply try disconnecting from such services turn of Bluetooth, AirPort, disconnect Ethernet cables, etc. If the problem does not persist, you can at least identify from which service the kernel panics are stemming, then approach the problem at a driver or settings level.
Kernel panics after the lid is closed Mac OS X portables sometimes exhibit a troubling issue where the system kernel panics after the sleep command is invoked by closing the lid of a portable. This can result in an issue where the system fails to go to sleep, and instead stays on and active while the lid is closed.
This can be particularly worrisome if you place your Mac portable in a bag after an incident, because the system will generally become extremely hot and fans will ramp to full speed. Remove any third-party items and check for persistence. Startup Items can also be the cause of kernel panics that result from conflicts with other software that is launched at any time other than startup. As such, don't count this location out as a harbor for problem-causing files.
External devices If it seems like external devices have been a thread throughout this article, look no further than the second paragraph for explanation. A common cause bears constant mention, and startup is no exception. Disconnect all external devices if you are having a kernel panic at startup or shutdown, and leave them disconnected until the system is fully booted. Then connect them one-by-one and see if the issue persists, either in general usage or at startup and follow the steps listed in the "External Devices" section above.

Bad devices FireWire and USB devices are second only to problematic memory in their widespread ability to cause kernel panics. For instance, the following Mac OS X components are all used by Apple AirPort hardware, and can be implicated by crash logs in kernel panics: com. AirPortAtheros IONetworkingFamily 1.
IOFamily This can be accomplished by entering the Energy Saver pane of System Preferences, clicking on the "Options" tab, then unchecking all options, including: Wake when the modem detects a ring Wake for Ethernet Network administrator access Restart automatically after a power failure If you can't find a reasonable clue for which settings to clear or change, you might want to try taking a blanket approach. For more on this technique, see our tutorial "Common workaround -- create a new user account" Another blanket elimination technique is to startup in safe mode, accomplished by holding the the option key at startup.
There's also a manual process -- delete the following most commonly problem-causing caches through the Finder or Terminal: com. Third-party software Virus software The category of virus software has emerged as one of the more problematic with regard to kernel panics.
