I could really use someone's help. I unintentionally ended up on a wrong site and my laptop was attacked. I have CCleaner and it shows calc.exe starts up when my OS boots up. After some research it seems like I have this. I tried removing it per these instructions, but unable to boot my PC in safe mode. I end up just getting a blue screen olf death message. Have run Malwarebyte's anti-malware but it doesn't help. Any help would be appreciated guys.
