They do not have their parsing scripts under control. Neither do they have or properly maintain a history of false positive strikes. Every time the same discussion starts over and over. Also they cannot provide any evidence about what is wrong; iif a file just post-loads data from a server (eg. CPU specific data like ARM, X86, MIPS, etc) - then it must be a virus in their eyes. This is highly unprofessional.

They falsely flagged our website as phishing. Even though their site states that they respond to false positive requests within 24 hours, after 4 days they still have not responded.
