It is simply not a good thing when your Anti-Virus starts listing off system files and says they are quarantined. It can really ruin your day.
According to posts at CA's Forum many people were receiving these false positives and causing systems to crash.

CA has posted an official statement apologizing for the incident and says that they are working to fix the issue caused by an errant file.
