I have had what looks like a Zone Alarm window pop up on my screen saying that my version of Zone Alarm is out of date and I need to click the image to update it. However I am suspicious as this method of update has never been used by Zone Alarm before.

Also if I go into Zone Alarm it tells me that I am fully protected. My version details are below:

ZoneAlarm with Antivirus version:
Vsmon version:
Driver version:
Antivirus engine version:
Antivirus signature DAT file version: 1126965248
ZoneAlarm Browser Security: 1.5.393.22
ZoneAlarm ForceField Spyware Scanner:

Can anyone tell me if this is Zone Alarm requesting this or whether it is malware?
