Internet browser updates are often made to fix security issues and running an older version may invite hackers into your system. Using good security practices such as avoiding unfamiliar websites, not clicking on suspicious email links and using unique passwords are important but running an outdated browser is still a major security risk.
Most modern browsers automate updates in the background and do not require any action on your part making it easier to stay up-to-date.

Business customers should contact their IT Administrator to determine which internet browser they should be using.
