If You not yet aware of, Adobe reported that sources of few of most used applications on user’s desktops worldwide is stolen.
As a result, we definitely should expect wave of new 0days and more sophisticated attacks. If all previous history of Adobe products not convinced You to remove them from Your machine, I think this is a time
First of all – do You really need Adobe on Your [or You're customers] machines?
For Flash: Many sophisticated streaming video services [Youtube as example] allow You to see it content without Flash, based on HTML5 technology for long enough. For others – well, You may consider usage of PepperFlash [same sources, originally]. You may download streaming files from bunch of services and watch them locally [VLC will help You out]. Or – not play games, decline to see ton’s flash ads and switch to non-flash alternatives of Your favourite services. Contact vendors, tell them – You not using Flash anymore.
For Acrobat Reader: You already have plenty of options to choose. Foxit, Nitro, Evince [my recommendations]. Yes, not all of them work with browser, not every application or webservice know to interact with them. Your PC – Your choice
OK, let’s start:
Windows: Uninstall Adobe Flash and Adobe Acrobat Reader from Your computer and reboot.
Linux: use Your package manager. If You have no idea, what I am talking about – You should learn about system You using, bit more. But, for instance – in graphical mode You have Software Center in Ubuntu and PackageKit in Fedora.
But that’s not all!
In Firefox You may even disable Flash or Block it execution on page, without Your permission.
To completely disable it: – Tools – Add-ons – Plugins – Choose Shockwave Flash Player and choose “Never Activate”. and then – restart the browser
To block it from execution: You may install nice add-on called FlashBlock, that will allow You to permit execution of Flash application once in a time. Here You still vulnerable, but now It’s totally Your decision, and not “good will” of person who create web page.
In Chrome You’ll need to disable internal Flash plugin.
Enter in browser address bar “chrome://plugins/” with no quotes, press enter and drill down till “Adobe Flash Player” brick will appear. Choose “Disable” and restart the browser.
In Internet Explorer You’ll need to go to Tools – Manage Add-ons and among add-ons find Adobe *, pick each one of them and click “Disable”, and then restart the browser.
Well, maybe after all those changes Internet became less familiar, bit more difficult to find suitable service, but definitely faster, and way more secure for Your specific computer.
