CyberLink Corp. - 0.02% Detection Rate *

Did you just download a file that is digitally signed by CyberLink Corp. and wonder if the file is safe? If so, please read on.

You'll probably notice CyberLink Corp. when clicking to run the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:

As you can see in the screenshot above, the Windows OS reports that "This digital signature is OK". This means that the file has been published by CyberLink Corp. and that the file has not been tampered with.

If you click the View Certificate button shown in the screenshot above, you can see all the details of the certificate, such as when it was issued, who issued the certificate, how long it is valid, etc. You can also see the address for CyberLink Corp., such as the street name, city and country.

VeriSign Class 3 Code Signing 2010 CA has issued the CyberLink Corp. certificates. You can also examine the details of the issuer by clicking the View Certificate button shown in the screenshot above.

CyberLink Corp. Files

These are the CyberLink Corp. files I have collected, thanks to the FreeFixer users.

The FreeFixer tool treats files from CyberLink Corp. as trusted, which means that the CyberLink Corp. files will appear with a green background and that there is no removal checkbox for the file. However, as you can see in the scan results below, a few of the anti-virus scanners detects the CyberLink Corp. file(s). My guess is that those detections are incorrect and that the files are safe. It's unlikely that CyberLink Corp. would ship a malware file.
