My son had False Alert Trojan on his computer which was detected and removed by Spybot. The Trojan also changed the Lan settings under IE which I had to go in and change. Everything is showing up clean now and working fine....except for Windows Security Center. It keeps showing an alert saying that his Virus Protection is out of date but it is not. It is on automatic update and a check shows that everything is up to date there. How to I get rid of that False alert?
