Cracking site that mate? Downloaded and installed (I have Vista HP, 64-bit) Comodo Firewall? By far, the most secure firewall I have EVER used!! Used to use Freeby AV's (Like Avast etc) but finally, went with Microsoft Security Essentials (another Freeby) and I tells ya what? The combination of the Microsoft package and Comodo firewall is by FAR, the best I have ever used!! I chucked-out Symantec/Norton despite having paid for it and prior to installing the package, I tried BitDefender Free Edition!! Talk about a program taking over!! Absolutely MASSIVE and DAILY updates, meant my PC was effectively unusable for up to 3-4 hours at a time!! Getting it out and uninstalled, was equally a nightmare (Despite I have Revo Uninstaller Pro!!) I still find bits of it (and Norton!!) every so often and when I come across them, I just delete the folders/files completely!!
Unless something drastic happens, I am more than happy with what I have TBH!!
