I haven't been attacked myself, this malware seems to target businesses.
This is a case where prevention is everything, once the attacker gets access to the target system
the AV is disabled, your files are encrypted, and you're locked out when you next try and log in.
The AV may help with the locked out situation, and clear up any residual malware, but the damage has
been done. You've lost your files, and in some cases, the backup too. I read about a medical
group that lost their patient medical and billing records. The backups, which were accessible through the
target computer were also deleted!
