Hi:
What can really go wrong?
I hope you were being tongue-in-cheek.
But I have a feeling you were not?
I rarely, if ever, never get virus's.
Viruses constitute a very small percentage of the malware circulating in today's threat landscape.
Most malware these days is non-viral.
Semantics aside, most users strive to NEVER be infected -- "rarely" would be once too often for me, that's for sure.
The bad guys exploit security vulnerabilities in older, outdated software in order to target their victims.
Malicious macros, scripted malware, trojans, ransomware, etc. can be delivered via "document" files.
Just a few examples of many reports:

https://nakedsecurity.sophos.com/20...malware-is-back-and-what-you-can-do-about-it/
As such, keeping one's OS fully patched and all of one's software likewise updated and fully patched is just one element to computer security "best practices" (Google this for links to many excellent resources).
While new versions of software also include bells/whistles and new performance features and may cost money (unless they are open-source), they also include hardened security features to help minimize risk.
As such, for example, Office 2016 would be inherently more secure than Office 2007 (extended support for which will end eventually, so that it will no longer receive even security patches).
It's impossible to protect 100% of computers from 100% of malware 100% of the time.
The first and last line of computer defense is the part between the chair and keyboard.
And even security-savvy users can be hit with malware, despite practicing safe hex.
Bottom line, again: it's entirely up to you. But it would -- at least to some extent -- improve your computer security to run a more up-to-date or open-source productivity suite.
That is just my personal opinion as a self-taught home user, not a computer security expert.
Cheers,
MM
