Eats resources, end process in task manager if not reading PDFs
When it hogs memory, delete from Windows Task Manager
This AcroRd32.exe process eats up 50% of the CPU time and problem is it cascades to all of my other processes but it's back to normal after i end this AcroRd32.exe process.
Has been causing crashes on my Vista for ages !
Once again, Jari Ahtiainen'a advice was excellent. I would never had suspected Adobe Reader for creating this problem. Now I can even listen to streaming radio :-) Thanks!
Jari Ahtiainen is right. found this setting and it cured the problem thanks ie in adobe got to edit, preferences, internet, uncheck allow fast view and uncheck allow speculative downloading
When ever I open any PDF file I get the error message: manual.pdf Adobe Reader: AcroAd.exe-Application Erroe. The instructions at 0x07000609c reference memory at 0x00000014. The memory could not be read. Click O. K. to terminate program. Then the PDF document freezes up.

Best practices for resolving AcroRd32 issues

A clean and tidy computer is the key requirement for avoiding problems with AcroRd32. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the AcroRd32.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
