Well..I would like to blog about this as This UKM... is full..hmmm..no..to be precise, is suffocated with autorun worms that duplicate themselves anywhere, any driver... The followings will actually reduce the chances of getting the worm into your system via pendrive(aka thumbdrive) when you need to load something from it.. For example, when you plug in your pendrive, your operating system will actually detect it and ask you what you want to do with it. So, that is autorun.
Autorun worms will actually hide themselves via several ways...edit your registry...something like hide your "run", disable your "regedit", etc.. Some good anti-virus software can detect it immediately once you plugged in your pendrive.. But, sometimes it might be too late as it already changed some of your system files.. So, by disable the autorun, you can save your lappie or PC with a higher chance(except you are facing some mutant autorun worm which can harm your operating system even without autorun it)..
go to start -> run -> type gpedit.msc -> click ok
the group policy thingy will pop out...click the '+' sign of administrative templates
click on system and browse until you find 'Turn off Autoplay' -> double click on it
the turn off autoplay properties will pop out.. click on 'enabled' and change from 'cd-rom drives' to 'all drives'
You are now saver than few minutes ago...
Specially written as people might ask this again and again.. haha..
