Yesterday we had a client bring in a desktop that wouldn't boot.. His teenager nephew had gotten at it over the holidays...and...well.. Completely destroyed it. With the help of bittorrent, limewire, etc, he demolished this guy's previously perfectly working computer. It was filled with infections, he had stupidity like spybot and stuff on it that begged for input if you even sneezed at the computer, the antivirus install that was on it was totalled.. He put firecrap on it because every teenager wannabe tech has to do that.. Totalled the Internet Explorer browser, totalled the task bar, demoed the control panel, trashed the Windows Installer. Being the brains that every young punk is, he disabled System Restore, disabled several key Windows services and got an infection which stripped the Admin accounts of their user rights. Oh.. And totalled the registry to boot. Then.. To top it all off, tried to put SP3 on it. The end result? Because it was an HP AMD computer, it blue screened and started rebooting repeatedly (Intelppm.sys)... Which ultimately totalled the partition. The long and the short of it? After hours of work, drive repairs, numerous repairs, repair installations, etc trying to undo all the damage the nitwit did, it still isn't perfect and will need to be backed up/reinstalled. So.. Yeah.. If any young kid tries getting on or at your computer, professing to be a tech.... Lock your computer down. Keep them far, far away... .....because a little knowledge is absolutely dangerous.
