To function correctly the Secunia PSI needs to be able to connect to Secunia's servers. If you experience any issues where the Secunia PSI cannot complete scanning or where the interface will not load and show you the detected programs, then please do the following.
Please note that some Internet Security Suites (Kaspersky Internet Security is currently an example) have their own settings for trusted sites. In case you are using such a program, you need to allow “https://*.secunia.com” as a trusted site in this program as well as in Internet Explorer. If you experience any difficulty doing this, please contact the vendor of the program.
If you are still having problems with the Secunia PSI, the services on which the Secunia PSI depends may have been disabled. To verify that they are running, type “Administrative tools” in the start menu search bar or open Administrative tools from the Control Panel.
Now click the Services tool and verify that the “Secunia PSI Agent” is listed and has its “Startup type” set to “Automatic”.
Windows XP users can also try the following: Navigate to the folder where you installed the PSI (usually C:\Program Files\Secunia\PSI). Right-click the file “psi” and choose “Properties”. Go to the Compatibility tab and place a check at “Turn off advanced text services for this program”. Click OK.
