Your computer should have a firewall and antivirus running on it to prevent hackers and viruses infecting your computer. The big question is, which ones, and how do you configure them to play nice with Medisoft?
There are MANY different firewall vendors, such as Norton (Symantec), McAfee, etc. Those choices are often costly, bloated, and difficult to configure.
So what's the Dibb Solution to firewalls?
Simple, use the WIndows Firewall that came with your computer. It's free, it's integrated into Windows, and it's easy to configure. But is it safe and secure? It certainly is, if not more so.
How do you configure the firewall on the server? (for Network Professional versions)
You need to ALLOW the program files below through the firewall. Every firewall application does this a little differently, I personally think Windows Firewall is easiest to configure.


Again, there are MANY different antivirus vendors, such as AVG, Norton (Symantec), McAfee, etc. Those choices are often costly.
So what's the Dibb Solution to antivirus software?
Simple, use the Microsoft Security Essentials, which doesn't come installed on your computer, but it is a free download and does a great job.
I also recommend using Spyware Blaster to help prevent malware from getting on your computer.
Make sure you set your Medidata folder Security and Share permissions with the following settings:
User Limit: Maximum allowed
Share Permissions: Everyone Change and Read allowed
Security Permissions: Everyone Modify, Read & Execute allow
