I did have a similar thing happen to me a while ago, though it was on Android.

My work used gmail for email at the time and so I added the account to my phone in order to check work email. Then I kept seeing applications installed on my device which I did not install. I uninstalled them but they kept coming back, and eventually I traced it to them being associated with my work account. IT said that they shouldn't have been installed on my device because I wasn't on some list, but they were, and they continued to be reinstalled every so often.

So I did the only sensible thing and got rid of the work account and email from my phone.
