Adobe Acrobat Reader DC - Free PDF Viewer
AcroRd32.exe is safe. It's Adobe Acrobat Reader DC, the free PDF viewer from Adobe. Different from Acrobat.exe (paid editor) - Reader is view-only with basic annotation features.
AcroRd32.exe (Adobe Reader 32-bit) is the main executable for Adobe Acrobat Reader DC, the world's most popular free PDF viewer. Available for over 25 years, Reader allows viewing, printing, and basic annotation of PDF documents but cannot create or edit PDFs (use Acrobat.exe for that).
Adobe Reader is the free counterpart to Adobe Acrobat Pro. It handles PDF rendering, form filling, digital signature verification, commenting/highlighting, and integration with web browsers for viewing PDFs online. The "DC" (Document Cloud) version includes cloud storage integration and mobile app sync. Reader is bundled with many software installations and is the default PDF viewer for millions of users worldwide.
Quick Fact: Adobe Reader has over 650 million users globally, making it the most widely distributed software after operating systems and browsers. The "32" in AcroRd32.exe refers to 32-bit architecture (even on 64-bit Windows), though Adobe now offers 64-bit Reader versions as AcroRd64.exe for better performance with large PDFs.
Yes, AcroRd32.exe is safe when downloaded from Adobe.com or official sources.
The legitimate AcroRd32.exe is NOT a virus. However, it's a common target for malware impersonation.
C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\. Files in Temp, AppData, or System32 are fake.Red Flags: If AcroRd32.exe runs on startup without PDFs open, uses excessive CPU (30%+) when idle, connects to unusual IP addresses, is located outside Adobe folders, or shows no digital signature, it's likely malware. Fake Reader installers from download portals often bundle browser hijackers, toolbars, or PUPs (potentially unwanted programs).
AcroRd32.exe runs when you open PDF files or when Adobe Reader is set as default PDF viewer.
