PrivaZer 4.0.115

PrivaZer 是一款專注於徹底清除電腦使用痕跡的免費清理工具，主要解決瀏覽紀錄、串流觀看、網路訪問等活動殘留可能被他人還原的隱私風險。它不只掃描系統，也能深入 USB 隨身碟與外接硬碟，將過去活動的殘骸永久且不可回復地抹除，同時釋放硬碟空間並維持系統安全。其最具辨識度的特色是掃描後會產生完整的網路足跡報告，讓使用者逐項檢視再決定清除內容。這套軟體長期持續更新，近一年內更新相當頻繁，在同類系統優化工具中屬於熱門選擇，使用者評價普遍不錯。

PrivaZer 適合重視隱私、常使用公用電腦或外接儲存裝置的人，尤其是需要確保自己看過、下載過或瀏覽過的內容不會被他人挖出來的情境。與 Glary Utilities 或 Rufus 等工具相比，PrivaZer 更聚焦在痕跡清除而非全面系統調校，功能取向較為單一，但深度更足。需要注意的是，它目前僅提供英文介面，且為 Windows 平台專用，免費授權但無中文版，對不熟悉英文操作介面的使用者來說可能稍有門檻，不過核心操作流程相對直覺，下載後即可免安裝使用。
