See if the system can access the MS Malware Protection Center:

Here's a direct link to the latest definitions for Windows Defender,
x86 [32bit]:
http://go.microsoft.com/fwlink/?Link...14&clcid=0x409
If not, check the HOSTS file located in
WINDOWS\system32\drivers\etc
for 'undesired' entries that may have been put there by malware.
If the system is being denied updates with the error code 80244019 in
Vista and WD can not be updated, that's a tipoff that malware is likely
present.
IF you receive an Access Denied error when attempting to view/edit the
HOSTS file: You cannot modify the Hosts file or the Lmhosts file in
Windows Vista
