I recently had the opportunity to install a security package across multiple laptops in a household. They used their laptops for business and personal work, including banking, so it was critical their data and private information was protected.
Overall, it took 4 hours to clean up their devices from malware, install and test the new security software and they were very happy with the result.
As part of their laptop usage was for business, they were able to claim a percentage back for tax purposes.
I will always provide an invoice but please let me know if any part of your setup is related so that I can remind you to put in for your tax deductibles.
