ok thx, translation: 
hi, I have installed Windows Vista, but the problem is that the protection from virus does not come recognized also with avast installed. can you help me?
This is an English-only forum. Sorry.
If you can use an automated translator.
As far I could understand Italian, I could ask you:
- Do you have any other antivirus installed in this computer?
- Did you have in the past, before installing avast?
- Do you use any other security program? Like a firewall, etc.

Although this was an XP related fix, it has worked for Vista also.
Windows Security Center not recognising avast!
Check this - Solution when Windows Security Center does not recognize antivirus or firewall
Did anybody test this on Vista? I’ve posted on my XP experience and I did not test it on Vista…
Seems that it should work, but it will be good to have an official (experimental) answer for this…

I know of at least one that has tried that fix and it worked.
