This morning, I noticed that TeamViewer was installed on my computer without my knowledge, and it was even running in the background. I keep my desktop tidy, so this was a huge surprise! I'm puzzled and a bit concerned. Could this be a sign of malware or a remote access tool? Should I consider reinstalling Windows?

TeamViewer does update itself sometimes and that might create a desktop shortcut without your consent, which is super annoying. But just to be safe, I'd keep an eye on your system for any odd behavior.
Check your Event Viewer! It might log information about when TeamViewer was installed, which could help you figure out the timeline of what happened.
If this was a setup executed by someone else, it could be a sign that your computer was accessed physically, or maybe even through a remote session. It’s a good idea to secure your system, possibly by creating a new user account with a strong password and moving your data over.
Usually, software can’t magically install itself. You might have accidentally installed it while getting another program, as it can be bundled with other software. A quick check of your installed programs sorted by date could give you a clue on what might’ve happened.
It's pretty strange for TeamViewer or any remote desktop software to install itself without some action on your part. If I were you, I'd recommend doing a clean install of Windows. It might be the safest option to ensure any potential malware is completely removed.

That’s true! Plus, be cautious about installing anything in the future. Always check those boxes for bundled software!
