PsynOptic

PsynOptic is a computer virus that mostly affects sweepers. It first appeared in Divided by Two.

Description
PsynOptic is transmitted digitally, through emails with the subject 'stinky cheese', but it can also spread itself with USB drives. Infected people go completely insane, and have a 45% chance of dying if the virus isn't cured in time.

Divided by Two
Due to the rotting conditions in their flesh vials, PsynOptic started to affect some sweepers. Two intentionally spread it to destroy the sweeper colony. However, more advanced sweepers were immune to its effects due to the higher temperatures of their flesh vials. Two tried to improve PsynOptic by exploiting new vulnerabilities.

In the trash compactor of a sweeper nest, more PsynOptic was found.

What Is The Internet?
As the Internet ceased to exist, PsynOptic stopped spreading.

Was It All A Dream?
When BFoury ship art and flesh vials flooded everywhere in the dream dimension, it was revealed the art was infected with both PsynOptic and the BFoury virus. Depending on what virus reached the brain first, PsynOptic was able to counter the BFoury virus' effects. Eye Pod 15 noticed that Psynoptic was faster.

Windows 1337 3
Cape Kragils found a USB drive containing PsynOptic. He tried to control the void and was absorbed by it, leading to everyone thinking he was dead. Cape built a portable guillotine out of the USB drive, and it chopped Yggdrasil in two.

Future Cape plugged a USB drive with PsynOptic into Cleverbot, but the latter was not intelligent enough to be affected.

NES Wellerman
Henryton was affected by PsynOptic 2.0, which could infect stickmin-plankton too. He almost died, but ended up surviving.

Patty in the Car
Foury got PsynOptic, despite not being a sweeper, robot or stickmin-plankton. She became one with the void, but was saved by Cape Kyrgyz. She, Cape Kyrgyz and Boyfriend went to find the creator of PsynOptic using the European bulldozer.
