This is a fix supplied from ZoneLabs. Give it a try if you are having this problem.

SUMMARY I’m getting a validation failed message with vsinit.dll

SOLUTION

In order to protect our software client from being tampered with, we sign our dll’s. Every time a dll is loaded, we check if it has our certificate.

In order to do certificate checking, the machine needs to have a root certificate on it. If the root certificate in missing, we can’t validate the dll and the client will not start.

We have determined that on systems with a validation error the root certificates were missing.

The Zone Labs client has 100% nothing to do with any kind of certificate removals and we can only assume that something malicious has removed them from effected machines.

The following 4 STEPS will fix your system if followed very closely.

STEP1: UNINSTALL ZONEALARM

Please follow the steps below to manually uninstall ZoneAlarm from your system. Please make sure to follow the steps for whichever operating system you may have. After ZoneAlarm is uninstalled, please make sure you have all of the Windows Updates installed and run a complete virus scan on your system to make sure there is not a virus on the system. You can run a free virus scan from the link below.
