What is ScreenUp? ScreenUp is a suspicious application that supposedly allows you to take screenshots on your computer, edit them and share them on different social media networks. At first glance, the ScreenUp application may seem like a safe and easy tool to use for taking screenshots. However, don’t let is seemingly legitimate interface fool you for this is categorized as a Potentially Unwanted Program (PUP) by our researchers after reading the application’s Privacy Policy and End User License Agreement (EULA). And based on its Privacy Policy and EULA, this application might gather information while it is running on your computer and might even share it with third parties. It uses the information gathered to display contents and ads according to your preference. Although it is still not considered malicious, but a potential threat, that does not mean you can trust this program, thus, removing it would be for the best.
The ScreenUp PUP could reach its users through different variants. What makes it suspicious is that the ScreenUp’s homepage does not provide any installer when our researchers tried obtaining it from the download button on its website. So there is a big possibility that it is distributed stealthily. Like most PUPs, malware, browser hijackers, and other threats, this application might be spread through bundled software which is one of the most common distribution methods. These software installers are bundled with other installers or additional tools which are also questionable. If you don’t read the terms and agreements or even pay attention during the installation, then you might get yourself an extra software or two that may threaten your computer’s security. Needless to say, if you want a clean computer without any infection, you should take time to inspect the software you are about to install and check if it has other bundled applications attached to it. It would also help if you scan the applications or any files you have downloaded from the internet using a trusted and reputable anti malware program like SpyRemover Pro.
What makes it even suspicious is that this ScreenUp application works without installing it.

According to its Privacy Policy and End User License Agreement documents, this application might be collecting information on your computer as well as your online activities such as your visited websites, login details like email address and password, etc.
