Destruction of nature & unwise use of resources, or even just multiplying to a point where even the most prudent resource management & minimal environmental impact per capita is the absolute goal could still destiny biodiversity.
This has to do with economical tendencies of living beings, not a particular socioeconomic system.
(Yes, capitalism is accelerating the process by taking away freedoms from the masses - but even a commune can decide to chop up the whole forest for wood. World is a fuck.)
"Virus" might not be the best word for it tho (infestation maybe? Fits the capita growth statistics), but successful animals that oversaturate their environment (eg lots of food, no predators, longevity after procreation, tech) cause biodiversity loss (anything from local collapse to a global extinction event with cofactors like climate change or air structure change - what is novel with humans is how rapidly we are developing in our last 0.5% of existence, and how rapid the global impact we case is, it won't take us 10s of thousands of years, we can speedrun in less than a millennia).
