Install Exclusively from the Google Play Store

Locate and launch the official Google Play Store application from your device's home screen or app drawer.
Search for 'Acrobat Reader' and tap the 'Install' button on the official Adobe listing to ensure a completely secure download.
Gather Information and Report a False Positive
If you downloaded the app from an official source and still receive a warning, it may be a false positive requiring support investigation.

Frequently Asked Questions
Why is my antivirus flagging a legitimate PDF reader?
Sometimes antivirus applications use strict heuristic scanning that triggers false positives, especially immediately after an app receives a major update. However, if the APK was downloaded from outside the official app store, the warning is highly likely to be a genuine threat.
Is it safe to install an APK from a third-party website?
Generally, no. Third-party APK repositories often lack strict security vetting, making it easy for malicious actors to modify and bundle malware, adware, or spyware with popular applications like Acrobat Reader.
How can I check if an APK file is truly malicious before installing?
You can upload the downloaded APK file to a free online virus scanning tool like VirusTotal. It will scan the file using dozens of different industry-standard antivirus engines to confirm if it poses a threat.
What should I do if my phone is already infected by a malicious APK?
Immediately boot your device into Safe Mode to prevent the app from running, uninstall the suspicious application from your device settings, run a full scan using a reputable mobile antivirus, and change passwords for any sensitive accounts accessed from the device.
