The thing is that early morning after turn on my computer (which has windows XP) I noticed the security alert logo of windows security center and it displayed the legend that none antivirus software was detected nor firewall.
But as you can see, norton is actually activated and working, I scanned the computer and it didn't detected nothing, I tried to return to a previous point on the recovery system and it didn't work either. I even reinstalled the antivirus and nothing.
Sometimes Windows Security Center stop recognizing the antivirus products. This what you should try: 1. Go to Control Panel -> Administrative tools 2. Open Services 3. Find Windows Managament Instrumentation on the list, ans stop this service (right click on it) 4. Find the Security Center service, and stop is as well. 5. Go to c:\windows\system32\wbem\repository ans delete this subdirectory ONLY 6. Close everything and reboot your PC (maybe you need to boot twice).
This will rebuild the deleted folder and the database. Once restarted, Windows Security Center should show the correct info and the security product should now be recoginized.
Unfortunately it didn't work, I rebooted many time and the folder (repository) from c:\windows\system32\wbem\ doesn't get rebuild. I read in many places that this method actually works in many cases, but unfortunately, there are times when this method doesn't work.
Unfortunately it didn't make the job too, the problem it appears that WMI is corrupted and that I need the windows XP installation Disk for fixing the problem, unfortunately thanks to my little brother the disk is lost. So I will try to see if some borrowed mades the job.
As long as you can get a Windows installation disk of the same version of XP Home /Pro / Media Center Microsoft has no objection to one using it for reinstalling provided you have the licit KEY for the one you bought.
But you also need it to have the same level of Service Pack as you are now at -- if you get the right, free utilities it's surprisingly easy to slipstrem the needed service pack to make a new edition of XP which has the same generation of all files.
Otherwise a repair installation or a System FIle Checker run will baulk when it has older files than the ones it is trying to replace.
If your PC has SATA drives and you are doing a full clean reinstallation (I'm not sure whether your aim is to do that or a repair installation) you need to have a copy of the driver on a floppy or slipstream that into the new disk also.
