Sorry, forgot to modify this for a virus-specific claim, but yes.
On solid copper, H1N1 decreased by 4 logs in 6 hours in this review; vaccinia and monkeypox viruses were reduced by 6 logs in 3 minutes in this study; murine norovirus was destroyed in 30 minutes in this study, though it doesn’t work very well at 4C; and another review says that copper oxide filters neutralize all of “bacteriophages [58-62], Infectious Bronchitis Virus [63], Poliovirus [61,64], Junin Virus [59], Herpes Simplex Virus [58,59], Human Immunodeficiency Virus Type 1 (HIV-1) [11,65-67], West Nile Virus [11], Coxsackie Virus Types B2 & B4, Echovirus 4 and Simian Rotavirus SA11 [68]. More recently, the inactivation of Influenza A [55,65], Rhinovirus 2, Yellow Fever, Measles, Respiratory Syncytial Virus, Parainfluenza 3, Punta Toro, Pichinde, Adenovirus Type 1, Cytomegalovirus, and Vaccinia [65]”.
Wikipedia suggests copper can kill at least influenza A virus and adenovirus. It seems likely that it would be effective against other viruses too, though not clear (to me) if it would work against every virus.
Killing bacteria isn’t the same as killing viruses. Do we have reason to expect the same efficiency?

In this context, is a log a factor of 2, or of 10 (or of e)?
Medical doctors, so 10
