Hi,
If the antivirus is not available in your plug-ins menu then the license has probably expired. Were you running Kaspersky AntiVirus for WinGate or were you running the Visnetic version? If you can find your old AV license key then you can enter it into our upgrade wizard and see if you are eligible for an upgrade discount.
You can download and purchase Kaspersky AV for WinGate from our website,
https://commerce.qbik.com/purchase.php, you can also upgrade your license to a 6 user license here. If you purchase your upgrade before July 1st then you will be eligible for a free upgrade to a version 6 license, also, the pricing for WinGate will probably be going up on that date so you are saving yourself money if you do this.
Best regards,
Matt
