This is off-topic, but it' is a security issue. And given the situation you described it is relevant to the conversation of maintaining good application control and security standards on your network.
There are only a handful of companies that are worthy of disdain in the IT world, Adobe is one of them. The last 2 years have seen some pretty major security breaches for them. Around this time last year they disclosed that servers they were using to compile code had been compromised, with hackers being able to digitally sign malicious code
using an Adobe cert. These certs are part of how UAC verifies if an application is malicious or not.
And just a few weeks ago Adobe publicly revealed that 2.9 million user accounts
had been compromised, along with an undisclosed amount of credit cards associated with those accounts. If that weren't enough source code
for as yet undetermined products was also taken after the accounts were accessed. Adobe has indicated that source code for Acrobat "may" have been targeted.
But complaining about a company being terrible isn't useful unless there is a good solution. Foxit
is a pretty awesome replacement for Acrobat Reader. I've been deploying it for users at various companies for years now and haven't had any issue with it. It's full featured and of the hundreds of workstations I've installed it on I can think of twice that there has been some kind of compatibility issue, and both of those were over 2 years ago. With the potentially severely compromised state of Acrobat Reader it is worth investigating if you can remove it completely from your network. If you sign up for a free account they will even provide a .msi of the installer with some xml (and if it's your thing) some group policy enhancements that allow for robust management of settings within the application (enforce security features, things like that). All for the low low cost of nothing. I am currently vetting the paid for version of Foxit for compatibility with features required for business processes, and if it is you better believe I am not deploying Acrobat or Acrobat Pro ever again.
