TQ, yeah - it's a bit complicated. I draw my private internet from my business line which has elevated security. I do have a hardware firewall which should have the private part configured as DMZ. But that Sonic Wall thingy seems to be overly sensitiv also blocking all kinds of URLs and I also had trouble downloading the Vive-Setup - I actually tethered my PC to the mobile for that. The firewall is setup by an external IT company and I lack the expertise to tinker with it alone.
I will get a second broadband line by the end - solely for private usage. So I either wait or try the tethering thing again - depending on download size...

It is a false positive. For some reason GAV heuristics got a bit more aggressive recently.
Either...
Go to Security Services/Gateway Antivirus, "Look Up Signature Containing String" and enter HLLP.E . Uncheck the enable button.
Or
Go to Network Address Objects. Create a group object and call it DPI-Bypass.
Create a host object, call it AH Downloads, IP address 67.228.0.74. Create another network range object call it HTC Servers, IP addresses 71.252.137.153 - 71.252.137.154.
Add the two address objects to the DPI-Bypass group object.
Go to Security Services/Gateway AV. Click on configure Gateway AV settings. Check the box that says "Enable Gateway AV Exclusion List". Select Use Address Object, and then select the DPI-Bypass Object.
(I'd recommend doing the same for antispyware, IPS, and App control).
