In 2010 you most probably have used bitcoin core (QT).

Do you still have a wallet file and are trying to see whether coins are stored?
If your file ends with .dat its a file from core.

Before trying to open your wallet, make sure to do several copys and back them up safely.
Also, if you think there might be 'bigger' amounts, don't simply put the wallet file onto an eventually infected PC.

The most secure way to check whether you have coins in your wallet would be to open it with the core wallet on an offline PC and check the balance of your addresses
on an online pc via a block explorer.
