how to remove a virus attack from iphone SE

I need help please with iphone virus attack after holiday in

spain

 My iphone SE seems to have virus or has been attacked after using on holiday in

spain

while browsing on return from holiday it said my iphone was being attacked and I should scan it now

I panicked not wanting to click on a possible scam site and shut down my iphone

on re-starting and opening safari it kept connecting to fridaynightwitchcraft.com ?

i couldnt get it to change from this page

I deleted safari from my home screen thinking i was deleting

the browser and then i could redownload it, but it seems I cant

Im stuck not knowing what to do and cant open safari (now not on my home screen) without

it loading this page fridaynightwitchcraft.com

 I have an iphone SE

Any help appreciated

thank you
