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.
