Update on Petya Attack
As noted by our on-site expert, krakatoa, the current vaccine for Petya involves creating a file called perfc in the C://Windows folder and making it read only. No kill-switch has been discovered, only a local vaccine.
If you see the reboot notification below, your device has been infected. Turn off your device to prevent future encryption. Petya begins encrypting the device an hour after the initial infection.
**Update: Petya begins encrypting your the first 1MB of your files prior to the reboot. See new post for the updated information. **
I've been using my MacBook Air laptop on and off for a couple of weeks now and I must say I'm suitably impressed with the Mac OS. It's turning out to be a surprisingly no-nonsense little workhorse. Though an avid Windows user for many years, I'm now finding myself wanting to reach for my MAC laptop far more often than my Windows laptop whenever I just want to just get some work done. The only thing I dislike about it is the built-in keyboard. A standard USB PC mouse (as opposed to an overpriced Apple mouse) seems to work fine for my limited needs as well.
It's not the first time I've used a MAC, but it's the first time I've actually seriously tried to use one productively. Frankly, I don't what the fuss is about with people who dislike this OS.
