Update WinRAR on Your PC Right Now

Last month a 19-year-old bug was discovered in WinRAR , the software many PC users use to extract .zip and other files on their computer.

While the company was quick to patch the bug, that match requires users to update their software in order to be safe — and a lot of people haven’t yet.

A recent report by Check Point Software revealed a potential security vulnerability in the UNACEV2.DLL library, which was used in former versions of WinRAR to decompress ACE archives.

Since UNACEV2.DLL had not been updated since 2005 and access to its source code is not available, the decision was made to drop ACE archive support starting with WinRAR 5.70.

According to McAfee , there are more than 100 unique exploits that can occur thanks to the bug, including one where hackers can extract a malicious file onto your computer’s startup folder that will automatically run the next time the computer is rebooted.

Luckily, there’s a quick and easy way to protect yourself against the bug and all the nefarious things that potentially come along with it: just update the software.
