A local auto body shop with multiple locations discovered the importance of preventative maintenance the hard way.
Their IT guy was part-time. He was the brother of the owner that ran around fixing PC problems as they cropped up.
Everything was going along fine...or so they thought. One PC became infected when a user clicked on a link from someone she thought was a friend. The virus started by attacking her computer first. Uncontrollable POP-UPS, CPU spiked to 100% causing the inability to run any commands or programs. She was forced to shutdown the PC, and when she rebooted, it would no longer load into the operating system.
This nasty little leech started replicating and attaching itself to files.
-The virus corrupted their data, causing important files to become inaccessible by the staff of 50 users.
-The virus impaired their customer management system, making it a nightmare to pull up simple customer records -and immediately brought down their Exchange server, meaning no e-mail could come in or go out!
Total business meltdown. All of a sudden it was like they were back in 1985, relying on phone calls and paper forms for everything!
