Hi, I am running Windows Vista Home Premium 64 bit which came with my HP Pavillion. I installed Malware Bytes along with an existing Mcafee install. Mcafee started acting up, so I uninstalled it. So, now I am running strictly Malware Bytes. Since the uninstall, I am getting a Windows Message that I should turn on Windows Firewall. When I try to turn it on, nothing happens. I still get the prompt to turn on Windows Firewall. I ran a full scan (twice, updating the DB each time) with Malware Bytes, no issues found. I went to Administraitve Tools/Services. It says that Windows Firewall is running along with Mcafee's firewall (?!). Should I be worried?
