Calendar spam

So I had the issue of calendar spam after being taken to a different website on google and having accidentally pressed the calendar Option on the pop up to make it go away.

ive now followed the steps to get rid of the “ clear your iPhone of malicious attacks “ on my calendar and now they’ve gone but I still have a couple questions.

1) do I have to reset my phone now the spam is gone from my calendar? I really don’t want to

2) I didn’t click on any of the links on the calendar spam I just got rid of it all so does that mean I don’t have any viruses on my phone now? Like no malware ( not sure if that’s the right word ) on it? ( also not sure if it counted as a virus in the first place )

id appreciate a response my anxiety is very high from this happening so thank you all in advance!
