PurePC protects your Windows PC in real time (signed threat definitions, YARA rules, behavior and startup monitoring, encrypted quarantine) and keeps it tidy with junk cleaning, a SHA-256 duplicate finder and startup control. No ads, no upsell pop-ups, and it works alongside Microsoft Defender.
One lightweight app for the protection and upkeep a Windows PC needs, with nothing you didn't ask for.
Reclaim disk space safely: your Temp folder, Windows Temp, Chrome and Edge caches, crash dumps, error reports and the Recycle Bin, without touching personal files.
Stop guessing duplicate files. PurePC uses a 3-tier matching engine (file size filter, 4KB header comparison, and full SHA-256 cryptographic hashing) with native folder browse selection.
Checks new files and programs as they appear, scores suspicious process chains, watches startup locations and quarantines confirmed threats. Designed to work alongside Microsoft Defender.
Lists your installed drivers and flags the sensitive ones (touchpad, display, audio), so you notice when Windows Update swaps a vendor driver for a generic one.
Apps you disabled turning themselves back on? PurePC manages Run keys, Startup folder items and scheduled tasks, and removes programs you no longer want.
PurePC never uploads your files, file names or browsing history. It checks your account and this PC's activation with CongoData, and optional cloud lookups send only file fingerprints (SHA-256).
Every feature is included with your free CongoData account.
