As others have said, your Gmail account can't download malware to an iPad (I won't use the word "virus" as that is technically incorrect). But if the account itself is compromised, i.e. someone else has got the username and password, it could be used to do nasty things to your android.
This is why the most important question is the one you have not answered: why do you think it is infected? Many people blame anything they don't understand on malware, even when in most cases it is not, which is why we have to ask this question. But if there is an infection then clearing that is important, and if the account is compromised it's important that you regain control of it (i.e. clean the phone, then change password and apply 2-factor authentication if you haven't already - and check for any unrecognised devices that have been used to access your account and deauthorise them if you find any).
Edit: ah, I see that the thread has moved on while I was typing this.
