Caused Blue Screens loops on countless computers due to faulty update in 2021

In March 2021, Kaspersky Anti-Ransomware Tool caused numerous business computers and servers to blue screen and become completely unbootable due to a faulty update. Kaspersky provided no solution and ignored the problem for months since this was "just" the free Anti-Ransomware Tool.   We had to restore backup images on dozens of workstations and others had servers go down.  The faulty update deleted all *.cat files in Windows making it unbootable.

Discraceful. WE WILL NEVER TOUCH ANOTHER KASPERSKY PRODUCT!

See this one of many forum posts about the chaos caused by Kaspersky - subsequently deleted by Kaspersky:
