At such times you may use these on-demand antivirus scanners. TIP: Test if Antivirus is working or not.
Check the identity of doubtful files
Malware can be named anything, and in fact, virus writers love naming them after some legitimate Microsoft processes or popular software. Check which folder it is located in. If the familiar-sounding process is located in the System32 folder – where it should be, it could be the legit MS folder. But if it is situated in some other folder, it may well be malware trying to pass itself as a Windows process. So do a search for the file, right-click on it and check its Properties and details.

Instead, press ALT + F4 on your keyboard to close the dialog box. If warnings, such as these keep appearing when you try to close the dialog box, it’s a good indication that the message is malicious.

Then navigate to the System Program Folder and delete all concerned folders. Run a registry cleaner after that. The Rogue may be easier to uninstall, but the Ransomware may not be!
