Japanese Shinto shrine sells low-tech IT amulets that promise to keep computers from freezing and restarting randomly, as well as free from viruses and malware.

Kanda Myojin, a popular Shinto shrine in Akihabara, Tokyo sells a variety of amulets and prayers, but none as intriguing as the “computer function amulet”. Consisting of a small, CPU-shaped sticker meant to be stuck onto the gadget in need of divine protection and a larger piece of cardboard meant to be worn by the computer operator, the amulet is one of the most popular items offered by Kanda Myojinm. If used correctly, the amulet will allegedly protect your machine from viruses, malware and random errors, as well as keep it from freezing up.

“If you are new to the IT industry, please be sure to buy this imperial guard, it is very effective (so far),” one presumably happy customer posted on Twitter.

Using antivirus software, staying away from shady websites and doing some basic cleanup usually keeps computers in working order, but if you’re looking for a low-tech alternative, this Shinto amulet may just do the trick.
