Microsoft recently announced that it would stop supporting older versions of Internet Explorer, which means a lot of businesses are going to need to take action very soon.

A survey from Manta finds that 61% of small business owners who use Internet Explorer are still using version 10 or older, which are those that Microsoft stops supporting on Tuesday.

“With less than 24 hours until Microsoft discontinues technical support for IE 8, 9 and 10, it’s surprising that more small businesses aren’t upgrading to prevent security woes,” a Manta spokesperson tells WebProNews. “While Manta finds that the majority of SMBs (37%) are avid Chrome users, 34% use Internet Explorer – a good chunk of businesses now subject to malicious security attacks if they fail to update.”

Microsoft said in a post on its website:

Beginning January 12, 2016, only the most current version of Internet Explorer available for a supported operating system will receive technical supports and security updates. Internet Explorer 11 is the last version of Internet Explorer, and will continue to receive security updates, compatibility fixes, and technical support on Windows 7, Windows 8.1, and Windows 10.

Internet Explorer 11 offers improved security, increased performance, better backward compatibility, and support for the web standards that power today’s websites and services. Microsoft encourages customers to upgrade and stay up-to-date on the latest browser for a faster, more secure browsing experience.

The company tells users to make sure to take action before January 12. Otherwise, you’re setting yourself up to be victim to malware and other exploitation of vulnerabilities.
