Did you just download a file that is digitally signed by Lavasoft Limited and wonder if the file is safe? If that's the case, please read on.
You will typically see Lavasoft Limited when clicking to run the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:
You can also view the Lavasoft Limited certificate with the following steps:
Here's a screengrab of a file signed by Lavasoft Limited:
As you can see in the screencap above, the Windows OS reports that "This digital signature is OK". This implies that the file has been published by Lavasoft Limited and that no one has tampered with the file.
If you click the View Certificate button shown in the screenshot above, you can examine 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 examine the address for Lavasoft Limited, such as the street name, city and country.

The following are the Lavasoft Limited files I've collected, thanks to the FreeFixer users.
The FreeFixer tool treats files from Lavasoft Limited as safe, which means that the Lavasoft Limited 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 Lavasoft Limited file(s). My guess is that those detections are incorrect and that the files are safe. It's unlikely that Lavasoft Limited would ship a malware file.
Here is the detection names for the Lavasoft Limited files. I've 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 Lavasoft Limited would ship a malware file.
