Agreed - as above, why does this have a virus? Extremely unprofessional. Either they're unaware of the virus and don't seem to care, or they're aware of it and are doing nothing about it. Not sure which is worse.
It's not a virus, just a false positive by your AV.
Wallets have an integrated miner in them which is detected by the AV. Since most miners they know of are malware, they assume this too is malware.
In some cases, when an actual virus is present, put there by scammer devs, you don't get 5 hits out of 66, you get 40-50 at least
