If you purchase photoshop from a trusted source, there should be no reason for the installation to contain viruses.
You might get an issue with the installation or program code (a bug), which Adobe will try fix for you. But no, if you install Photoshop from the Adobe website or from an electronic store you should not get viruses. However, if you attempt to install it from a second party website or try to get it free, there's no telling what will happen.
