The software you're describing with **a yellow icon** that cleans computer junk and categorizes it into **color-coded areas** is likely:
### **CCleaner**
- **Key Features**:
- Cleans temporary files, cache, cookies, and other system junk.
- Uses **color-coded categories** (e.g., blue for system files, red for privacy-related data) to organize cleanup tasks.
- Icon: A yellow broom 🧹.
If this isn't the exact tool, alternatives with similar functionality include **Wise Disk Cleaner** or **BleachBit**, but they typically lack the yellow icon and color-coded categorization.
