No malware from Intuit but if you bought it from an unauthorized source that could be the problem. another issue, if the CD is legit, is that the digital security signature certificate with the CD is invalid. it's been updated (march 2024) but you can't update (or install) with the virus protection turned on.
one thing to try before disabling the VP at your own risk, is to try using RUN as administrator (assuming windows computer and UAC as administrator)
other help should come from support
