Volume in daw

Try turning everything else down, you'll probably find it's them that's too loud. You'll probably also find after you've put overdrive, eq and/or other effect processing after the Virus it'll be a bit louder anyways..

While Lidge's advice is what I'd do, there is an Ableton device called Utility which you can drag on tracks that lets you boost volume (among several other things). I've used it at least once before on a couple tracks whose source volume was simply too low.

No real way to turn up the Virus alone, it's pretty quiet on its own.

You need to turn everything else down so it's on the same level, and then boost the whole mix.
