We have 10 PCs. 5 are Windows XP and 5 are Windows Vista. Windows Vista do not have any service pack installed on them. All PCs have access to the internet successfully through a proxy server. All PCs has Panda antivirus software installed successfully. The problem that we are having is that on Windows XP, Panda antivirus were activated and updated successfully, however on Windows Vista we were not able to activate the Panda antivirus software or updated with latest virus signatures.
The conclusion is that Windows Vista does have access to the internet through a proxy server, but unable to update Panda antivirus software. Can someone help me with this. Thanks.
