KeePass & DeepScreen thing

Avast Free Antivirus / Premium Security
1

Whenever I start KeePass from my usb stick, it’s bordered by this “DeepScreen” thing. After opening a database and a few seconds, presumably Avast restarts KeePass - this time without the DeepScreen thing around it.

At work, this does not happen. Same Avast, same usb-stick, same program. Which is absolutely great, because this DeepScreen is not helping me in any way. On the contrary - it’s only working to have me type the password twice, and to kill KeePass every first time. Can’t be too good database-wise.

First of all: why does this happen?
Secondly: how do I disable it?
Last: how do I tell Avast (the company) that KeePass doesn’t need or want whatever this DeepScreen stuff is?

/edit
Sorry, forgot to mention in my haste of reporting this problem:

  • Windows 7 x64
  • Avast engine 2014.9.0.2018
  • Avast defs 140630-1
  • KeePass 2.26

Shouldn’t matter too much, because no version of an antivirus solution should get in the way of any user using any program, imo. But at least it says something about the recentness (is that a word? :))) of my software.

Eh, thanks, but I wasn’t literally asking what DeepScreen is. But thanks to you I understand that it’s some form of protection against low-level malicious code.
But:

  1. KeePass is not malicious, so how can I whitelist it from DeepScreen?
  2. Can Avast whitelist it in their defs? (and how do I go about getting them to do that?)
  3. It kills & restarts KeePass without notice, which is bad no matter what (so how do I get the Avast devs to fix this issue?)
  4. Why am I not getting this on every pc that has Avast installed? Since I don’t know how to whitelist it, it can’t have been whitelisted on the pc that doesn’t show the DeepScreen thing…
