Any way to harden more the firewall security - getting a lot of risky ip blocks?

Hi, Is there any way to harden more the firewall security from McAfee Internet Security? because I'm getting a lot of risky IP blocks from the firewall (1000+ IP Blocks within 3 days with PC shutdown half the time)?

I'm not a forum expert, but from what you are seeing the McAfee firewall seems to be doing its job by blocking those connections, that's exactly what it needs to do!

If you still feel at risk, you can go into firewall setting, select "Traffic Controller" and instead of the default of "Smart Access" you might choose "Stealth".

However, be aware that you may get prompted to make complex decisions by the firewall because it is handing over some of the control to you, so you need to be experienced...otherwise, simply leave it on "Smart Access" and it makes all the decisions for you, that's the setting that I use.

Another option is to go into firewall settings, and this time choose "Intrusion Detection", and then enable the "Basic" recommended option. This can give you greater protection.

There is a way indeed. 

1. From traffic controller choose stealth mode.

2. From My Network Connections find the name of the network you are connected to and set it public. 

3. On Intrusion Prevention, turn on the function and set it to aggressive.

Hope that helps.

Can get this much but really high. Mine set on default Smart Access and got way lower than that could be sites you usually visit. I rarely venture off my normal sites so my amount could be low.

Try the stealth setting though I never needed it. Asked before

It may be normal, depending on the environment your computer is in. The McAfee firewall rejects traffic on certain vulnerable ports, it rejects traffic that was unexpected and it rejects traffic from risky IP Addresses. Other vendors do the same, but they just won’t provide you with the numbers. You’ve got nothing to worry about and nothing to harden.
