Every time I start my computer, I notice that two empty .tmp files appear on my C drive, and I'm really puzzled about what's causing this. I haven't installed anything new in almost a year, and I always verify my downloads through VirusTotal. I can delete these files without any issues, but they come back with different names upon restarting. Can anyone explain why this is happening?

Have you tried using Google? Sometimes it can lead you to the answers you need, but just be careful because not all info online is reliable.
True, and it turns out I figured out the issue is related to my Minecraft launchers! So much for Google helping this time.
A cool tool you might want to try is Procmon from Sysinternals. You can set it to boot mode, and it’ll log everything happening during startup. You just need to search the log for those .tmp files to see what’s creating them. Just a heads up, the log can get pretty huge, so make sure to turn off boot mode when you’re done.
Thanks for the tip! As it turns out, I found out exactly what was causing the .tmp files. They were being created by two mod launchers for Minecraft. I turned off their auto-launch setting and poof – no more mystery files after a restart! I actually saw them being created right when I opened the launchers. So funny!
Glad you figured it out! Those launchers can really leave a mark if they’ve got bad coding.
If you’re worried about malware, it might not hurt to check out a malware guide to ensure everything is clean. But it sounds like it's more of a software issue with something that's running at startup.

You can't always trust everything you see online! Be cautious, especially when it comes to potential tech issues.
