I suggest you to temporarily disable your antivirus program and to download the screensaver's setup file, but without installing it onto your PC. Once the downloading process is completed, upload the package onto VirusTotal web page and click the Scan It! button. If the package is infected, delete it. If not, install the screensaver, enable the antivirus and go to Virus & Spyware Controls. Click the Advanced Settings button from the right side, press the Ignore Specific Files and Folders option and then click select. Press the Add Folder icon, navigate to Amazing Universe Premium Screen Saver directory and click OK.
