defender and windows update not updating- trojan?

  john the scone 08:39 13 Aug 10

hi there, recently got message that windows defender out of date although set up for automatic updates. didi it manually and all ok but keeps coming up so having to download definitions manually as it never completes its own updates when i click 'check for updates now'. now getting message, ' windows cant check for updates' when it has updated. again clicking 'check updates now' never finishes checking. been no problems previously and i've not changed anything recently. using avira antivir personal which is up to date but found nothing and malwarebytes anti malware which found trackers and deleted them. read that might have a trojan bho.dll but not found anything. any help much appreciated.
2.1ghz core2duo, 2gig ram,vista 32bit home premium, all spacks and up to date.

You could try switching off automatic update. then reboot and then try downloading them manually and see if that works.
if not switch automatic update back on and try again.

Or go into services and make sure Windows update is set to automatic.

thanks for reply, but all automatic updates are turned on, its like the message contradicts my settings! can download manually but that doesn't stop message from returning. you cany re install defender as built into vista.

Never had Vista so can't comment.
I don't suppose it gives you the option of repair in add remove.
That of course was for w/defender.

The easy fix for windows defender is to install Microsoft Security Esentials, it will disable defender and takes over most if not all of its roles so no more update problems
