What is rundll32.exe?

rundll32.exe is part of Windows, and is used to run program code in DLL files as if they were within the actual program. However, many viruses also use this name or similar ones. This file is also commonly used by spyware to launch its own malicious code.

rundll32.exe is a crucial Windows process, but like other Windows processes, some malware will copy the name in order to infiltrate your system.

Try this:

Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter.

Now download the free version of Malwarebytes' Anti-Malware (MBAM). Install it, get updates and run a full scan (still in Safe Mode). This is a direct download link. Copy and paste it into your browser’s address bar, and press Enter.

After that, boot normally and run another full scan with MBAM. It will detect any malware that wasn’t running in Safe Mode.

If the problem still exists, download and run the free Kaspersky Virus Removal Tool:

You should now delete the Kaspersky Virus Removal Tool, as updated versions are often made available. Malwarebytes' Anti-Malware can be easily uninstalled, should you wish to do so, but it may prove to be beneficial in the future.

Hope this helps.
