I have Avast 4.8 Professional antivirus.When I tried to open Windows Firewall, dialog box said : "Due to an unidentified problem, Windows cannot display Windows Firewall settings. " Is that mean the Firewall is off. What cause this problem?I tried run "Firewall.cpl" to fix the problem but nothing happend. Also I run "regsvr32 hnetcfg.dll" and it wrote that it was succesfull , but I still can't open Windows Firewall.I had some malware -win 32, but I supose that computer is clean now. Also my Themes service isn't working . I run "services.msc" but every time when I tur on computer Theme service is not working. 1 person needs an answerI do too

Avast Professional has its own firewall component which will correctly disable the built-in Windows Firewall. Your computer is behaving exactly as it should. That said, it is badly out of date with only Service Pack 2. Do maintenance and then install Service Pack 3.http://www.elephantboycomputers.com/page2.html#Maintenancehttp://www.elephantboycomputers.com/page2.html#Removing_MalwareWindows XP Service Pack 3 Network Installation Package for IT Professionals and Developers (Microsoft Download Center)http://tinyurl.com/6k9zo3Prerequisites for a successful installation - MVP Harry Waldron - http://tinyurl.com/6nf4k4 Steps to take before you install WinXP SP3 - http://support.microsoft.com/kb/950717 MS-MVP - Elephant Boy Computers - Don't Panic!
