Hello there 2917hubert and welcome to Bleeping Computer.
This topic has been hotly contested over at the Secunia Forums and, as best as I can tell, if you are running Windows 7, you shouldn't worry about this issue.
The angry discussion and the...*ahem*...lack of an informational response from Secunia can be found here and here.
I'm running the 2.0 version of PSI and after several scans and reboots, I'm now showing 100%...even though I never updated to 6.0.
I'm chalking it up to a False Positive on Secunia's part. And thus far, I'm having trouble finding anyone anywhere that's telling me (or posting) different.
I've been losing a wee bit of confidence in Secunia over all as of late, but it's still a dang handy app to find that out-of-date stuff on my Windows side of things.
Hope that helps and, again, welcome.
