Why is Internet Folder Cleanup set to run twice a day?

Internet Folder Cleanup is set to delete unused or old Internet folders and files that are older than 14 days twice every day to improve your Internet performance. Old or unused Internet folders and files clog up your PC's temporary memory capacity and slow down your daily web surfing. Internet folders and files that are less than 14 days old are often from web pages that you frequently visit and PCCare will not delete these files.

Running this task twice daily allows you to keep a reasonable amount of internet cache on your system without keeping clutter that can slow your internet activity down. Two weeks also allows you to leave your PC for a few days without having your important recently visited internet cache deleted.
