Computer Issue or...

Hi, I'm having a couple of issues with my HP laptop. I'm running Windows 10, which just updated three days ago. I'm a heavy print-at-home person so, I am vigilant about keeping my computer up-to-date on updates, drivers, anti-viruses, malware, etc., because I'm a writer. I also like to keep it clean of browsing data, cache, cookies, history, etc, to keep it from slowing down. I assume in my OCD of keeping it "cleaned out", I must have deleted something I shouldn't have. When I go to print, I receive two messages: "We've detected a Security Issue." Please exit any screenshot software or virtual machines you may be running and make sure your printer is not set to a PDF writer. and then try printing again." To my knowledge, I don't have such software installed. The second message; Error 202. I was told to get a registry cleaner, but as I was reading on some of the Microsoft forums, that doesn't sound like a good idea. Today, I did a rollback from the Windows 10 Fall Creators Update version 1709 to the original version. I'm completely lost as to what to do. If someone could help, I would be ever so grateful. Thank you.

Causes of HTTP Error 202

• Virus or malware infection that has corrupted or taken control your internet browser.
• Corruption in Windows registry from a recent Windows-related software change (install or uninstall).
• An external rogue program has maliciously infected browser-related files.

Your internet browser can display Error 202 as a result of malware infection. These malicious problems can cause your internet browser to behave in very undesirable ways and cause Windows registry corruption, creating even more annoying error messages.
