Doctor Web Ltd. Files

The following are the Doctor Web Ltd. files I have gathered, thanks to the FreeFixer users.

The FreeFixer tool treats files from Doctor Web Ltd. as safe, which means that the Doctor Web Ltd. 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 Doctor Web Ltd. file(s). I'm pretty sure those detections are false positives and that the files are safe. It is unlikely that Doctor Web Ltd. would ship a malware file.
