Would Windows 7 firewall functions if I uninstall McAfee?

My PC is l670-1john family windows with MacAfee install by default

I have never activate MacAfee.
Windows firewire is controlled by MacAfee
Firefox is block by firewire, I check configuration of firewire. It seems ok.

If I uninstall McAfee windows firewire will be functional?

Thank you

Hello

Yes, Windows 7 firewall is an internal function that would be always available even if McAfee would be uninstalled.
You can also enable or disable the firewall from Win 7 following way:

1. open Windows Firewall by clicking the Start button, click on the Control Panel, clicking Security, and then click Windows Firewall.

2. click on turn on or off Windows Firewall.
If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

3. click on (recommended) and then click OK.

  • Windows Vista Firewall: Uncheck basic network layout would make my computer more secure on the Public network?

    I use the Public network a lot.  I noticed that on my Windows Vista firewall, Core Networking is checked on by default.  Unchecking it would make my computer more secure on the Public network?  I already checked in my firewall settings, block all incoming connections.  Regarding security, I run MSE, like Spyware Blaster in the background.  Automatic updating and Malware Protection are on.  My other security settings are OK.  I do not understand why Core Networking is checked on by default.  This would make an open port, right?  Unchecking it would make my computer more secure?  Thank you.

    I heard that the windows firewall is not very good compared to as comodo and protects against incoming traffic. I have also been informed that it tends to have be restarted whenever a system is restarted. Is this true please.

    HitBit

    Hello

    Not those who are not true.

    Low-cost 3rd part firewall software are quite a lot of problems delayed. They are all
    have compatibility problems and offer only a few improved controls. Indeed their questions often
    actually lower the overall security rather than raise. The Windows Firewall has no compatibility
    questions and is extremely secure if you know enough to work around most of the hype. Quality software
    firewalls cost thousands. Most of the hardware firewall routers built in and are considerably
    better additions for your money than any firewall software to low-cost and low-cost.

    If you want to uninstall OR have uninstalled any security antivirus/antispyware/program don't forget
    to go on the manufacturer websites and search for removal tools (these can be performed after uninstalling if
    required) or special instructions to uninstall. Otherwise it will leave causing trouble

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leave the file system, Web,.

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that

    I want to use the DLNA (Digital Living Network Alliance) media streaming on my home network and VPN connections.  I need these features in my Windows 7 Home Premium 64 bit guests and clients Ubuntu.  Windows 7 firewall cannot determine enough about VMware network adapters, the labels 'unidentified' and public brand!  Perhaps it is because I am visually impaired and use screen readers, but I'm not able to define these connections as private or disable the firewall for these connections.  If I disable these adaptors or uninstall Workstation, these features work perfectly.  Of course, this will not allow these characteristics never to work in a guest and is not a viable solution for the Windows host either.  Does anyone have a solution to know how to enable VMware networks bypass bad decisions of Microsoft network design?

    When comments computers connect to the network via ethernet, they would get an IP address outside this range and I don't want the hosts to be able to see or communicate with desktop computers and vice versa.

    I created the inbound rules and outbound for tests that denies everything outside this range of IP (extended tab has the range specified in the remote zone "IP address") and it seems to work.  For the "local IP address" I chose "any IP address" - the documentation says: "select this option to specify that the rule matches a packet network for any address as the local IP address.

  • Windows 7 firewall, just after the power rules

    Hello

    Setting up a private workgroup-to-peer network (not homegroup, no servers or domain) of several PC windows 7.  Have all network connections, defined as 'private' of networks.  At that time, the private firewall is disabled, and the Public firwall is enabled.  Administration tool using remote third 3rd RAdmin connect and control the PC.

    Strange behavior just after turn on/off the PC.  Can ping from one PC to another, but RAdmin tool fails to connect to a PC on just.  The 'Public' windows firewall log shows the RAdmin TCP packet dropped.  Once someone has logged on locally to the computer and then connected to the wide, the RAdmin packages are no longer considered (fell or permitted) by the Public firewall, and the RAdmin progam works great.

    I added a test rule to allow all TCP traffic through any firewall from any PC, any user, any port, etc. (essentially large open) and still have the problem where RAdmin specific TCP packets are lost by the Public firewall.

    I can get it to work by setting the 'incoming connections' for the Public firewall to 'Always allow', but is not an acceptable solution.

    I worked with the provider of 3rd party s/w (famatech) and they also have no idea why it works this way.

    Any ideas how the Windows 7 firewall works right after that the PC is on, but before the user login?  Any ideas how can I do an acceptable firewall rule which will be in force after powering on, but before that the user log?

    Thank you in advance for any help or any other ideas,

    Answered my own question.  Found that a set Local GPO do not merge rules defined by the user.  When I moved the RAdmin rule throughout the local Group Policy object, problem goes away.
