What anti-virus solutions are you guys using? I currently have 4 Plesk-servers, but still have no virus-scanner on them. I am unwilling to pay $$$ for Dr. Webb. I prefer an open-source solution, so 4PSA is no option as well. Are there people here who have been able to get Clamd AntiVirus or any other virus-scanner working on a Plesk server with Qmail?
