TeamViewer - 0.164% Detection Rate *

Did you just run into a file that has a digital signature from TeamViewer? If that's the case, please read on.

You will probably see TeamViewer when double-clicking to run the file. The publisher name is then displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:

You can view the additional details from the TeamViewer digital signature with the following steps:

1. Open up Windows Explorer and locate the TeamViewer file
2. Right-click on the file and select Properties
3. Click the Digital Signatures tab
4. Click the View Certificate button

Here is a screenshot of a file digitally signed by TeamViewer:

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

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 TeamViewer, such as the street name, city and country.

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

TeamViewer Files

These are the TeamViewer files I've collected, thanks to the FreeFixer users.

The FreeFixer tool treats files from TeamViewer as trusted, which means that the TeamViewer 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 TeamViewer file(s). My guess is that those detections are false positives and that the files are safe. It's unlikely that TeamViewer would ship a malware file.

Scanner and Detection Names

Here is the detection names for the TeamViewer 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 false positives since it is very unlikely that TeamViewer would ship a malware file.

* How the Detection Percentage is Calculated

The detection percentage is based on the fact that I've gathered 2438 scan results for the TeamViewer files. 4 of these scan reports came up with some sort of detection. If you like, you can view the full details of the scan reports by examining the files listed above.
