As the owner of 2 iPhones, 2 windows laptops, 1 windows 2 in 1 tablets, 5 kindle fires (some rooted with custom android stock while some are still stock kindle fires), 6 android phones, 3 android tablets, etc I can honestly say that this is NOT just an apple problem!!! It occurs on multiple operating sytems, multiple devices and multiple browsers and there is no clear cut solution that consistently resolves this problem! While just deleting your browsers history and cache doesn't fix this problem it does help in the respect that when you attempt to go to a website your browser will automatically attempt to load speed up your browsing experience by using the saved cache from your most recent visit to that site thus by deleting your browsers cache you are forcing it to go the actual website url you type in. So deleting browser cache and history will help somewhat but there are a few other things I would recommend as well. Check your browser settings, especially your cookies!! If you see that you have enabled cookies, especially 3rd party cookies with no restrictions you are effectively giving every single website, ad, link, etc that you click on the ability to put cookies in your device that can not only track you but also make changes to your system!!! Also, while having settings like preload top hit, suggestions, quick website search, and other browser optimization services enabled your are basically going to be directed to the exact websites/ip addresses of those that you have visited quite frequently - aka you are more likely to be taken to a website which compromised your device already. Last, ALWAYS use https and not http when going to a website as it is more secure. I wish there was a 100% clear cut solution for this problem but the reality is that there are so many different types of security flaws, malware, viruses, etc that are affecting browsers and devices regardless of whether you have an apple product, android, pc, mac, etc. Wish I had a better answer, if anyone does please let me know, but I hope this helps somewhat.
