The installers for GExperts 1.3.15 were/are detected as malware by several virus scanners on Virus Total. I have since submitted them all as false positives to Kaspersky and some to Microsoft and after their latest signature updates their scanners are now fine. I tried the same with other virus scanner vendors, but their procedure was so complicated that I decided that it is not worth the effort. So if you are using BitDefender or McAfee, you might be out of luck. Try to submit your installer to them yourself if you like, just so you see how much time that takes. Now multiply that by 19 installers and > 10 virus scanners … I guess you will understand then why I don’t bother.
