Updating Adobe Reader within Mac OS10.9.1

Question

I am having difficulty in updating to the latest 11. The installer keeps on crashing before installing the update. Thank you for your help
This is the following error message, I have switched off all virus protection and tried also switching off my firewall protection but still same error.
Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x000000009a50656e

Answer 1

My Reader 11 did the same thing.
I tried the FULL installer from here (http://get.adobe.com/reader/enterprise/), and it failed EVERY TIME.
I eventually uninstalled it completely, using AppZapper.
Then I downloaded it fresh using the "stub installer" here: http://get.adobe.com/reader/?promoid=JZEFU and for some inexplicable reason, it worked.
Something you posted though, makes me post the following link: https://discussions.apple.com/message/23885605#23885605
You have no need of antivirus on a Mac, because what it's designed to detect and protect you from.... DOESN'T EXIST. It's not only a waste of money (if you're using something you paid for), but far more often than not, it'll do more harm than good.
I presently run four different Macs with 10.6.8, 10.7.5, 10.8.5 and 10.9.1 with NO A/V on any of them. These are Mac numbers 9, 10, 11 & 12 that I've owned in eleven years and I've never had a single virus on ANY of them, going back to 2003, and I've never had ANY anti-virus software on any of them, with the single exception of a paid, 6-month-trial I did for McAfee, on an isolated partition of my G4 eMac, in 2004.
Whatever you've got, you can and should, get rid of immediately and completely. Even if you run Virtual Machines, or Windows with BootCamp, you ONLY need A/V for the VM or the Windows partition. NEVER on OS X.
