Ok maybe someone here can help. My sister and I each had this off brand digital pet that dealt with viruses. There were different types of viruses and you could have them travel small levels and fight and explore to find items I think. It was from the 90s for sure, maybe 97 98 or 99. I'm certain I had a blue version and they were supposed to be able to link up somehow. I just can't find what it was anywhere!
