For security purposes on my PC with Windows XP Home Edition SP2 all up to date. I use Comodo Firewall--AVG Antivirus free edition-- AVG Antispyware free edition--Spyware Blaster-- Windows Defender all used regularly and kept up to date. Last week AVG Antispyware found a Trojan called KillAV and quarantined it. My AVG Antivirus which does its daily scan at 0800hrs had not picked it up that morning and the previous antispyware scan with AVG which had been done two days before also hadn't picked anything up. I immediately did another scan which picked it up and quarantined it again. I deleted them both this time and did another scan which found nothing. That night I also did a Windows Live One Care scan which again found nothing other than the usual temp internet files etc.
I have paid particular attention to my PC's behaviour since then but everything seems to work normally apart from the following incident.
The day after the above happened I went to sign into my PC and found that although the little sign in box with my name was there the little flashing print icon wasn't and I therefore could not sign in. I rebooted my PC and everything has worked well again for the last week until this morning when the same thing happened again. After the first time I changed the passwords on both mine and my daughters (who shares this PC) accounts as a precaution.
As I say other than this happening twice my PC works just as it always has but perhaps someone could tell me how to stop it happening again. Many thanks in advance for any help offered.
