Very likely it is not, but the only way you can know for sure is to get it tested. There are often visual signs of virus, some are pretty telling, but in truth, there are a number of other pathogens and cultural issues that can produce similar looking results.
At the end of the day though, if you suspect it's got a virus, it's best to just toss the plant and not risk it. Particularly if you have other orchids.
