How to fix
Non-responding “Save As” Function
on Windows

When I click on the button, it does not respond and goes blank. Do you have any idea how to solve it? Can it be possibly a virus?

Non-responding or "Save As" function might be the result of several problems. Thus, it is important to identify the issue when and under what circumstances the error appears. It might be tied to a specific application or occur momentarily.
In some rare cases, malicious presence might be at fault for such behavior. In that case, make use of [d1] application. Run the scan for any possible threats. If the cause lies not in a fraudulent file, you might check the following methods.

Option 1. Repair corrupted registry files

Some users have reported that they were able to solve the problem by running the incorporated System File Checker. For your surprise, indeed it may come in handy if files got corrupted.

1. In Windows OS, right-click on the Start button or Windows key+X and choose Command Prompt(Admin).
2. Once the application launches, enter sfc /scannow.
3. Wait for the process to finish. If the non-responding Save as function was a result of corrupted system files, a notification should appear indicating them. Finally, the program will inform when the problems are repaired.

Option 2. Reinstall the faulty program

Naturally, if you cannot save solely .pdf or .doc files, you might try reinstalling Adobe Reader or MS Office. Speaking of the former option, some users reported that the program contained bugs which resulted in the function failure. Make sure you download the legitimate program. Adobe Reader and Adobe Flash Player often happen to be hackers’ manipulation tools.

Note that in Adobe Reader DC (Document Cloud), “Save as” function works a bit differently. You can save the files in the cloud storage or in a previously used location. When the application attempts to store the file in the cloud, “Save As” function may not function properly. You may need to disable the cloud storage location function.

Open Acrobat's preferences, navigate to the General tab and remove the checkmark from Show online storage when saving files. This option might be especially practical if you experience the issue on Mac OS.

Option 3. Install current Windows updates

If "Save as" error happens from time to time and you cannot pinpoint the case, you might attempt to install all current Windows updates. It is common sense that Windows 10 still has a number of bugs, so interrupted installation of a specific update may have resulted “Save As” function failure.
