When I go to upgrade my copy of Secunia PSI by following the update link at the bottom of the Secunia PSI screen I then get the message that the program I am trying to run has no valid digital signature and when I follow the link created by Internet Explorer Security Warning that says " how can I decide what software to run? ", it tells me I should not run it because it may have been tampered with. What's a guy to do? I am running XP SP2 on a HP 4400+

XP Pro, AMD Athlon X64 X2 4400+, 3Gb Ram

Sounds like your internet settings need to be reset. I know the following instructions are for scanning but it probably would be worth following them to correct the settings. Worth a try post back & let us know if this works or not.

You could try this:
The Secunia PSI needs to be able to connect to Secunia servers to complete its scanning. However, if you have configured
the security settings of your Internet Explorer, the Secunia PSI may be prevented from getting the scan results. To receive
your scan results, you need to do some changes to your Internet options.
To do this:
a. Open Internet Explorer.
b. Go to Tools>Internet Options>Security tab.
c. Select the Internet zone and click on the Custom Level button.
d. In Security Settings, go to the Scripting>Active Scripting option.
e. Make sure that Active Scripting is Enabled (rather than Disabled or Prompted).
f. Press OK then Yes.
g. Back in the Security tab, select the Trusted sites zone and click on the Sites button.
h. Look at the bottom of the page and take the tick from the box marked"Require server verification(HTTPS)for all site zones" then type in the following and press the Add button to add them to the Trusted Zone Sites list:
i. Press Close
j. Run the Secunia PSI again to view the scan results
Both sites will now be OK
Good luck & regards,
