Why is GlassWire flagging itself as malware under the VirusTotal column?
GlassWire itself may occasionally be flagged as malware by VirusTotal as a false positive. If you have any concerns about this please email us, or post in our forum so we can help you.
Please remember VirusTotal is not an antivirus, but it’s a file analysis service.
Thanks for posting this. I already emailed VBA32 on March 4 about this false positive and I have not yet received any response. You can also visit their website and report this under their “support” email to help get it resolved faster.
