I need to deploy an antivirus solution for someone who is using Windows 7 64-bit. I need to know that out of all free and paid apps, which ones have a true 64-bit version. I know MSE and HitMan Pro have them, but not aware of others. Please help. P.S. - I know that 32-bit apps work fine on 64-bit machines by using a native 64-bit driver, but still if you can cater to my whim, I would be grateful.
