Should I Switch, and To What?

Have always used Norton, and Yahoo products, back to the 80's!  Question, with all the hoopla about hackings, should I consider changing my email accounts, and computer homepage from Yahoo to another company, and, if so, change to what? I'm hearing that iGoogle is a good (&secure) homepage, as well as Gmail.  There are alot of orphan companies out there for email and homepages, but I'm rather conservative and prefer a known entity. The big issue, in my mind, is: should I worry about switching at all, since the hacking took place back in 2013, and Norton has kept me very safe ever since it was called Norton Utilities!  Also, with Yahoo possibly being sold to Verizon, should this affect my decision to switch or not?

Thank you for your assistance!!
