Have you taken steps to determine for sure if your system has a virus?
Is the image of the system from before you suspect it was infected with a virus? An image made after an infection is in place will be no help at all, it will include the infection and will restore the same infected system.
If the image is from before you feel the infection occurred, did you create an Acronis boot CD? If not, in TrueImage, choose the Create Bootable Media tool and write a bootable CD. Since you suspect the computer may have a virus, you may wish to create the recovery CD on another computer just to be safe.
Once you have (or if you already have) bootable media, boot the computer from the CD with the external drive containing the image connected to the system. If offered the choice of Safe or Full versions, choose Full.
When the Acronis recovery environment boots up, you can choose to restore from an image - locate the image on the external drive and choose to have it restored to the system's original internal drive. That drive will then be returned to exactly how it was when the image was made.
If the image you made was after the suspected infection, you won't be able to use it to generate an uninfected system drive. You would have to reformat and re-install Windows, or confirm and clean the infection from the existing installation.
