Hi wls,
You read the vendor's comment for an end of lifetime product.
Anyway one is ill advised to use a Windows platform with full user rights for online activities other than downloads/patches. 97% of malicious software is known to do none or considerable less harm if it does not have access to the system to run, and using normal user rights does that.
Furthermore the question is theoretical as physical access to computers means it is compromised anyway,
