How can I protect my PC from other admins at work?

You should consider firewalling your machine to block incoming remote access and change local policies to restrict login access. It’s odd though, your approach seems like you’re trying to hide something from IT, and as a sysadmin, you should already be aware of these measures. Just ensure whatever scripts or tools you have are company-approved.

Honestly, it seems a bit questionable. If the company owns the device, they have every right to see what's on it. What’s really concerning is your fear of them scanning your work. Maybe evaluate whether you have any private scripts that should be company resources instead of stored personally.

Given that you're claiming to work in a government position, there could be more scrutiny involved. If someone’s using admin privileges to check your logs without prior consent, that’s highly problematic. Remember, privacy on corporate devices is pretty much non-existent.

I'm curious about what specific tools they're using for the scans and what data you're concerned about them discovering. If the tools are legit and the scans are routine, you might not have anything to worry about.

It sounds like this situation is a little sketchy. Depending on your company’s policies, they might be violating some rules by doing these scans. I’d recommend checking what the official policies are before taking any further steps to protect your data.
