I recommend:
- Uninstall Bluestacks App Player via Control Panel. Look for unknown applications and uninstall them as well.
- Download and install Malwarebytes (free version from malwarebytes.org) and CCleaner (free version from piriform.com).
- Run Registry and Cleaner scans using CCleaner (save a backup copy when asked, just in case).
- Run a Custom Scan with Malwarebytes, selecting all hard drives / SSDs and Scan for Rootkits; if any malware is found, accept the defaults.
- Uninstall all Intel graphics drivers found via Control Panel.
- Delete that funky Intel folder.
- Reboot.
- Allow Windows Update to find and install the Intel graphics driver (reboot if asked).
- Run Registry and Cleaner scans using CCleaner (save a backup copy when asked, just in case).
And from now on, always use the below website to check the reliability of applications before installing:
