Suspected scam

No iPhone (unless one which has been jailbroken) can get a virus. So yes, it's a scam. Do not give this scam artist any information.

Is this from iMessage? If it is DO NOT CLICK IT delete the message and report the contacter and block them. If you clicked it they will have put a virus on your iPhone. I just visited the website on our virus-safe computer (one that is ok to get viruses, we erase it all the time) and yes they put a virus on the computer by attempting to download a bunch of files. Don't ever visit that website and always question messages like that, especially the ones that say something like 'You have run out of time! click this link to be free of your debt! Act now or lose your home!' it is illegal to send these messages and nobody will make you rush like this either. DO NOT INSTALL THE REPAIR EITHER. Your iPhone is most likely perfectly fine and they just want to steal your money or break your iPhone.

"...If you clicked it they will have put a virus on your iPhone...."

No.

A second NO to "if you clicked it they will have put a virus on your iPhone"

Simply NO.
