Hi there,
Since updating avast! to latest version, Action Center no longer recognises Avast anti-virus or anti-spyware modules. Have tried a repair install and a clean/reinstall. Anyone else noticing this?
Sometimes, Windows Security Center or Actions Center stop recognizing your antivirus or firewall… So, check your system time and date and also https://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=580
