Microsoft windows says that the 2008 Quickbooks installation disc has a Trojan Horse virus

Please know that QuickBooks (QB) 2008 is no longer supported by our system due to its outdated status, Boliver1936. 

To begin with, is the CD from Intuit or a third-party vendor? As this plan is outdated and no longer supported in our system, we are unable to provide additional assistance. You may want to seek guidance from an IT expert to help with removing any possible viruses.

However, we cannot assure the success of the installation as the installer is discontinued and not compatible with the present system. You may want to consider using QB Enterprise or QuickBooks Online.

 We also have resources for QuickBooks Online and QB Enterprise to guide you through your next steps:

• QB Enterprise Q & A.
• QuickBooks Online Q & A.
  
  

Furthermore, I will share these two valuable resources in case you need them regarding the service discontinuation of QuickBooks:

• QuickBooks Desktop 2022 service discontinuation policy.
• Learn how features and data move from QuickBooks Desktop to QuickBooks Online.
