How to protect your forums from malware or viruses?
 

What are the best ways that you are applying to protect your forums from malware or viruses?
I am considering to buy and install a service like this (ModSecurity Rules from Malware.Expert) on my WHM/cPanel to keep my websites against malware or viruses. What is your experience with them? or you can share your methods to against malware or hackers for your forums/sites or blogs?

Thanks in advance.

I believe this is something that most reliable hosts should be willing to help and assist with. If they are not, I would look for another host.
