Internet Explorer is sort-of dead nowadays, and Microsoft have moved on to Microsoft Edge (originally code-named "Spartan" in the very early Windows 10 development). I recommend you switch to Microsoft Edge or Firefox; I don't recommend Google Chrome for privacy reasons.
Microsoft Edge also has its own AppContainer usage (built-in to Windows 10) for enhanced mitigations against attacks to its processes, thus further protecting you from some variants of banking malware (Zeus will be mitigated for example - it just won't be able to inject code to install its form-grabber). Firefox isn't very good in this aspect compared to Microsoft Edge or Google Chrome though - Google Chrome are 2nd place for this, Microsoft Edge being first place. -> from personal testing, because I managed to find a bypass for the Google Chrome AppContainer for normal DLL injection without it being aware.
Opera is allegedly quite good but they've had some suspicious banking government website connections lately, and I didn't like some things I found during investigation with hard-coded URLs to services like Conduit and MyStart (with zero explanation or information online for their documentation), so I'd personally avoid that web-browser as well. They were recently bought by a Chinese company for a lot of money, so I expect it to be a data collection and data selling service now.
Yandex is well liked by a few members here like
@Sunshine-boy and
@ForgottenSeer 58943 (I think?) and it appears to have some form of Host Intrusion Prevention System, aimed at protecting its web-browser. Therefore, protecting its processes from external third-party source attacks, also beneficial for preventing banking malware and similar. However, I've not had a chance to test it out because I could never get it running for me, nor do I know much about them/their privacy guidelines.
I'd say using Internet Explorer is a security risk and a bad decision, but each to their own.
