my antivrus detected a trj win32:spyware-gen. whats the best to do with these ?delete or move to vault. ?

i have avast home edition and spybot. is it enough to deal with them?

You can either delete the trojan or move it to vault. Both options will be safe enough. A virus / trojan in the vault is completely harmless, as it stays isolated from your system.
Of course your Avast! and SpyBot are enough to ‘deal’ with the trojan, as Avast! has already detected it!
