Lenovo - 0.033% Detection Rate *
Did you just download a file that has been digitally signed by Lenovo and wonder if the file is safe? If so, please read on.
You'll probably see Lenovo when clicking to run the file. The publisher name shows up as the "Verified publisher" in the UAC dialog as the screenshot shows:
You can view the digital signature details for Lenovo with the following procedure:
- Open up Windows Explorer and locate the Lenovo file
- Right-click the file and select Properties
- Click the Digital Signatures tab
- Click the View Certificate button
Here's a screenshot of a file digitally signed by Lenovo:
As you can see in the screenshot above, Windows reports that "This digital signature is OK". This means that the file has been published by Lenovo and that no one has tampered with the file.
If you click the View Certificate button shown in the screenshot above, you can view 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 Lenovo, such as the street name, city and country.
Symantec Class 3 SHA256 Code Signing CA - G2, VeriSign Class 3 Code Signing 2010 CA and Symantec Class 3 SHA256 Code Signing CA has issued the Lenovo certificates. You can also view the details of the issuer by clicking the View Certificate button shown in the screenshot above.
Lenovo Files
These are the Lenovo files I've collected, thanks to the FreeFixer users.
The FreeFixer tool treats files from Lenovo as trusted, which means that the Lenovo files will appear with a green background and that there's 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 Lenovo file(s). I'm pretty sure those detections are incorrect and that the files are safe. It is unlikely that Lenovo would ship a malware file.

Scanner and Detection Names
Here is the detection names for the Lenovo files. I have grouped the detection names by each scanner engine. Thanks to VirusTotal for the scan results.
As mentioned above, I think these detections are incorrect since it is very unlikely that Lenovo would ship a malware file.
