Some Background: My dad has asked this friend (Bob) for tech help many times in the past, so much so that Bob had him install one of those GoToMyPC programs so that he’d have remote access any time.
This was innocent at first until recently, my dad woke up and got pop-ups saying his drive was too full to open any of his work programs. When I went over, we restarted it and noticed the PC asks us which version of Windows we’ve like to boot. We tried both, Windows 1 was my Dad’s regular laptop, still giving us the full HDD pop-ups. Windows 2 had only 1 user profile: Bob. we can’t access it, and we can’t delete anything from it on my dad’s user (not that I know of).
I’m not sure if I can fix this myself, but I’d like to try so that my dad doesn’t have to bend to this dickhead’s will.
I remember troubleshooting a client issue that amounted to their anti-virus creating extensive logs that filled their C drive. Maybe there is a bugged piece of software doing something similar.
Maybe you can follow the steps here and see if there are some abnormally large files to get rid of. If you come across any culprits, I might pop the filename in Google and see if there is a known piece of software or malware that is creating the file.
Strangely this happened to me but it was something I figured out because I was trying to install a game and didn’t have enough space. Was a super weird bug that I found mentioned on some obscure forum for whatever antivirus I was running at the time (maybe Avira?). Funny that you mention it haha.
