It is easy to learn whether the file was or was not encrypted since the affected ones should have a second extension called .sigrun, for example, flowers.jpg.sigrun. Soon after all of the malicious applications targeted files get encrypted, it should place files called RESTORE-SIGRUN.html and RESTORE-SIGRUN.txt in every folder containing locked data.Sigrun Ransomware Removal GuideSigrun Ransomware screenshot
