Everything seems to be working like it should. I had to uninstall McAfee then reinstall it to get it to work. The .dat file still hasn't changed, so that is good. I don't see any errors when I restart, that is good, as well.
Just a few follow up questions, if you can.
I am going to use Spywarebot and Malwarebytes.
I am going to use McAfee for an antivirus and PC Tools for my firewall. I will turn off all other firewalls.
I have also installed SpywareBlaster; I think this is for Java.
Can you recommend anything else or do you know if there are any compatibility issues with any of these products?
Thanks again for your help
