My old job had viruses everywhere when I started. Machines hadn't been wiped for decades and even their antivirus licensing server was down because of malware

I spent months reimaging every machine in that place. I kept everything updated and the PCs running like new. Meanwhile, my senior coworker and our vendor pissed around for a replacement backup solution for over a year after the old one failed during a restore.

Eventually, I quit for a better opportunity. A few years later EVERYTHING got ransomware there. I only found out because months after the attack they had asked a local community college for help imaging machines because it was going slower than expected due to their senior guy going to Vegas.

Like wtf. This was a mental healthcare place. You should have called professionals. Instead you asked if their are any students that can help because you sent your senior guy to fucking Vegas.

So glad I left that place. Still wonder if they had a working backup.
