i had zone alarm pro 5.5 and after geting continous popups for update to new version i finally decided to upgrade to zap 6. after installing i found out that kaspersky auto updates are not running.even after manually trying to update kav i was not successful. so i manually configured zap to give kav full acess but updating was not sucessful. so i decided to roll back thru xp system restore. heres where all the panga started.during system restore the pc got hanged,i manually restarted it and now all i get is just the wall paper on booting and a popup that true vector servcice(zaps) has encountered a problem and will be shut down. the pc stays on that screen. what can be the solution for this problem?
