. At present.. I am using ClamWin Anti-virus as a back-up on-demand only virus scanner. It has no real-time protection scanning features as this was the job of my other anti-virus. But the only problem I noticed w this anti-virus was that it is very slow in its scanning process. Maybe it’s one of the best, but if it takes too long to finished the job then this could be probably be used only once a year. What’s yours? Is it fast and effective?
