Well, Kaspersky Antivirus Pluigin for WinGate generally scans HTTP, FTP and Email traffic, and can also do manual scans of drives or files.
So if these 4 viruses came down via a direct connection without going through a service that has the plugin scanning, then that could be a reason why they ended up on your computer. Viruses can also come from the local network or by inserting disks into the WinGate server.
Personally for my home installation, I have the KAV plugin scanning my drives weekly, and I use a free AntiVirus solution (currently AVG) for real-time monitoring of the server.
