How do you make the sounds on the virus wider?

It depends if the sound is mono-heavy or not. The technique effectively cancels the centre channel. So, on mono sounds (but with a bit of stereo reverb applied), you'd be left with just the reverb, as the central mono channel would cancel out and just leave you with the wishy washy stereo reverb tails all on their own.

It's also how karaoke machines work to subtract the vocals from a pre-mixed track. (Traditionally vocals are mono and panned centrally. But so is bass, so that generally cancels out too.).

Try reducing the centre-channel in this way on just individual audio track subtly - by around 20%, or similar - then compress it to bring it back up. All the extra surround sound information will be enhanced and boosted, but with the central channel reduced, so depending on the stereo data being treated the overall panarama should be widened up moreso (but, again, losing slight mono compatibility for that particular musical channel - not by much, though, if you've only processed it by 20% or so at most).

If not, your sounds are too mono to start with. The above technique only acts on stereo information that's already there, so otherwise you'd need to look at the source material itself and get some modulation happening.

Look at a phase-meter (showing lissajou patterns in realtime) to see what kind of stereo information is happening. I use the one in Wavelab v5.
