On XP machine when going from one page to another I am prompted to allow access to xpsp3res.dll. Does anyone know what this means? It doesn't happen all the time.

Thank you.

Does this happen when you're browsing webpages? If so, internet explorer or Firefox, or something else? Xpsp3res.dll is the Windows Security Center, as far as I can tell... we'll need the above information to help you further :)

You may want to try a malware scan with Malwarebytes, from Malwarebytes.org in the meantime.

Yes, while browsing web pages.

Thank you
