So, I recently bought a pc on OLX (an app that you can sell and buy stuff) the man that sold to me appears to be a really nice person and I got a really good price for my hardware. It’s about 2 months since I bought it and it came reseted with windows installed. I notice that there were some apps on it and when I questioned the man he said it was just apps to check the performance of the computer, but sometimes when I alt-tab I see two random softwares open that I don’t recognize: Home Cloud and another that the name is really weird, Form1 Should I be worried or am I just paranoid? EXTRA: every time I try to click on it nothing happens and also I can’t find them on the list to uninstall
“Form1” is the default window name when you make an application using the Windows Forms toolkit.
Either this person created their own application or they used a homemade application written by someone else and run it on the PC. This sort of thing doesn’t need to be installed. It might be set up to autorun as a service or a scheduled task and run in the background.
It might be a harmless custom tool they used to set stuff up and forgot to remove, or it might be something unpleasant.
In the real world, a workman leaving a tool behind isn’t a safety risk in quite the same way as it is in the software world. I would recommend following other comment’s advice and wiping the PC and reinstalling windows.
If they are a 1-man operation, it is much more likely they would be tempted to try something suspicious than if they are part of a team with supervision, oversight, and accountability. A place where the consequences for being discovered would be much more severe.
