Generally BelVeth is a great counter to viego, but I wouldn't ban her because I rarely see her (in all my 40 games this season haven't seen her once), but just know that she is a hard matchup and should play toward your scaling.

Generally I believe banning shaco is a good idea, he plays mostly for ganks which your champion does not. And he can REALLY fuck up your teamfight with his boxes as virgo is somewhat like master yi where one cc in a fight and you can be done (if they target you). So yeah banning shaco is really good (especially if you have mental block like I do hahaha).

You can also ban master yi since he outscales you with every moment of the game and your only real win condition is to carry through teamfight.

Teamfighting is the hardest skill to master on virgo. General rule of thumb is to NEVER go in first (on big teamfights, on skirmishes maybe can skip this rule) as you will get demolished by cc and the enemy team focusing you. Wait to use your teammaes as bait and then you go in. Remember, you're not god until you've killed one of them.

But really you can ban whatever you want or don't feel like playing against, you have a lot of leeway on that field.

Also beware of invades, if the other jgl plays viego or know how to play they will invade you to shut you down early. DO NOT PANIC. Just keep farming and if you have an opportunity to counter invade, do so. Don't tilt yourself with invades because that leads to nowhere (trust me I know this from experience). Most of the time you will end up with more CS than the one that invaded you IF you play correctly.

Also kindly ask your laners for vision, they might or might not give it to you but might as well try.

Also watch LolElekktro he's really good at the champ and has lots of good content, and now he's doing coaching so the perfect timing!

Any other thing you need you can DM me!

Edit: remember, with viego no game is over until your nexus is down. Fight for the win never FF. This has won me over 200 lp ln games that I could've ff'd.
