Having the latest version of your software can be a good thing because in most cases, the newer software versions contain the latest security updates as well as any bug fixes for issues in previous versions. Adobe Reader should be periodically reinstalled.
Both Mac and PC have other programs that will read PDF files, and because of this, I actually have changed my position on this matter over the years. If you don’t really care what you use to read your PDF documents, I recommend you uninstall Adobe Reader from your Mac and PC. Mac users can open PDF files with Preview and PC users can use Microsoft Edge. This can help improve your machine’s performance too.
On a PC, do not remove Adobe Flash. This software is updated through Windows Update.
If you are running macOS High Sierra, open “Finder” and then open “Applications.” Locate Adobe Reader and then move that icon to the trash. You may need to give permission by entering your Apple ID and Password.
To reinstall Adobe Reader on your Mac, go to Adobe.com and scroll to the bottom of the web page, then select the link “Adobe Acrobat Reader DC” on the left. Select the “Download Now” button and it should begin shortly. Once it has downloaded, select the “down arrow” in the circle icon at the top-right of Safari and then you will need to double-click the “AcroRdrDC” file to begin the installation. Double-click the “AcroRdrDC” package file to continue. Follow the remaining instructions to complete the installation. Once installed, you can move the installer to the trash and close all the windows.
If you are running a PC, I have the same recommendation that I stated for the Mac. You can use Microsoft Edge to view all your PDF files, so unless you use Adobe Reader for other purposes, or you prefer Adobe Reader, go ahead and remove it from your computer.
If you do want to reinstall Adobe Reader, open your control panel and then click “Programs and Features.” Click “Adobe Reader” and then click “Uninstall” at the top of the list. Click “Yes” to give your system permission to continue. Follow the remaining instructions to uninstall Adobe Reader and then restart your computer.
To reinstall Adobe Reader on your PC, go to Adobe.com and scroll to the bottom of the page and on the left, click “Adobe Acrobat Reader DC.” Follow the remaining instructions to finish the installation.
Installing a fresh copy of your software can give you added security, but it can also help your computer’s performance.
