I was in the Matrix room (via Element) yesterday when a raider spammed some extremely illegal, extremely reprehensible content. I didn't see it, as I had the chat minimised, but it was still running at the time of the incident, which means whatever was posted was saved into my cache. I found the cache, deleted it, uninstalled the app, deleted my account, and removed all traces of Element from the computer. However, I'm terrified I might have missed something, especially as I'm on a shared PC. The app was only installed on my own profile, but I worry something could have been saved in the temp folder, or something like that. Do I need to do anything else to keep my PC safe and make sure the cache is gone for good? I'm sorry if I'm being overanxious, but I don't want to have that garbage polluting the PC.
