Can i have an instagram on a computer?

I don't have an ipod ipad or iphone can i still go on instagram?

I think there's something called webstagram.

I don't know there's webstagram but I think it's a virus

Yes, you can, but you don't have a news feed, you can just see specific people's profiles and your own. To access someone's profile, you need to go on: instagram.com/(their username)

I think webstagram is only for viewing profiles. You can also get it on an Android

Yes you can. Webstagram is an Instagram viewer. You can also get it on Android. When you are on the web, you can't uploaad photos. Also to log into your Instagram on Webstagram, you had to already made an account on an Android or Apple Product.
Ask your friends or parents if you can borrow their phone so you can make an account, you can later log on to it on the computer, even though you can't post from the computer.
Hope this helps
