A rar file is a collection of files & folders wrapped into a single package and compressed using the Roshal Archive algorithm. It was first released by Russian software engineer Eugene Roshal in 1993. It purports to have better compression speed, encryption and error handling than the ZIP format. RAR Extractor not only unpacks your RAR files, but it also lets you peek inside and preview images, documents and even emails. Fine-tuned for speed, RAR Extractor works quickly without consuming a lot of memory or hard drive space.
For some reason your Windows has set a file association with Internet Explorer To reset the file association, right click a rar files, choose Open With - choose another app, check the box marked 'Always use this app to open rar files' Then if you cannot see the old app you used to open rar files, click 'More apps'.

I will probably have to restart my browser and delete temporary internet files. If you're using Internet Explorer, Edge, Chrome or FireFox, try deleting your temporary internet files and see if there is any change.
