I recently ran a Malwarebytes scan with Medicat, and I'm really concerned because I got a blue screen error on my PC that showed "DRIVER OVERRAN STACK BUFFER" before the scan. I'm anxious because this could indicate the possibility of malicious code on my machine. Can anyone help me understand what to do next?

You might want to gather dump files for better analysis of that blue screen error. If you can start Windows normally or even in Safe Mode, check the WindowsMinidump directory for any crash logs. Zip up any files you find and upload them to a file-sharing site like MediaFire or Catbox. This can provide more insight into what's causing the issue. Also, make sure you have followed the instructions to set up small memory dumps for future BSODs.
Just a heads up—Malwarebytes can sometimes flag harmless files as threats, which are known as false positives. It might be a good idea to send whatever it thinks is suspicious over to VirusTotal for a second opinion before you panic.
It sounds like that blue screen isn't necessarily due to a virus but rather a bug in a Windows driver. However, it's definitely wise to check for malware as well. First, try downloading HitmanPro and make sure to disconnect from the internet while scanning. After that, boot into Safe Mode, run Malwarebytes, and remove anything it finds. You might also want to do a Microsoft Defender Offline scan. If your PC is still acting strange afterward, consider reinstalling Windows using a USB drive.
