A management, visibility and explanation layer over the security Windows already has. It adds no scanning engine of its own, and if another security product is active it is left exactly as it is.
Version 1.22.0 · Windows 10 and 11, 64-bit and 32-bit · runs on your PC, opens when you want it
The honest positioning
My PC Doctor works with Windows Security and Microsoft Defender and adds security intelligence, visibility and assistance around your PC. If another security provider is active, My PC Doctor respects the existing protection.
What the Shield covers
Each area below is available in the app today, described as it actually behaves. Where an area has a limit worth knowing, it is said in the same line.
Microsoft Defender & Windows Security — Available. Which antivirus Windows is actually relying on, how Defender is running, its engine and intelligence versions, and thirteen Windows protections listed as on, off, or held off by another product.
Smart Firewall — Available. Windows Firewall in plain words: which network class this PC is on, which programs are already allowed, and what to do when a billing or accounting program cannot connect.
Web & download security — Available. Check a web address before you open it, and a downloaded file before you run it: HTTPS, the certificate, the shape of the address, the publisher, the signature, the checksum and where Windows recorded the file coming from. Good to know: When nothing is known about an address or a file, the app says so plainly rather than showing a green tick that would mean nothing.
USB Shield — Available. Know what’s connecting to your PC. What is plugged in, whether this PC has seen it before, and what shape a pen drive’s contents are — then Microsoft Defender’s own scan of it, when you press the button.
Application Trust — Available. Know which applications are trusted on your PC. Every installed application with who signed it — Verified, Known, or Needs Review — identified by publisher, digital signature, certificate and SHA-256 rather than by file name.
Ransomware Protection — Available. Help protect important files with Windows security. Whether Windows is guarding your Documents, Pictures and Desktop folders, what it has stopped, and how to let a billing or accounting program you use through. Good to know: The protection itself is Microsoft’s Controlled Folder Access. My PC Doctor explains it, switches it on through Windows’ permission prompt and shows what it did.
Security Center — Available. One place to understand security events across your PC. Defender’s findings, firewall decisions, website and download checks, USB activity and applications in one list and one timeline — only what somebody actually has to decide about, with what happened, why it matters and what to do.
Signal Correlation — Available. Security signals, explained together. My PC Doctor correlates security signals — a new USB drive, an unsigned program, a Defender warning — to help explain events that may need your attention, and shows every signal behind a conclusion. Good to know: It explains what Windows and Microsoft Defender recorded. Only Defender ever calls something a virus.
What it is not
Stated plainly, because the difference matters when a customer is deciding what to buy and what they already have.
It has no scanning engine of its own.
It never switches Microsoft Defender off, and never removes an antivirus you bought.
It has no kernel driver, does not inspect network packets and does not decrypt traffic.
It never offers a way around a Windows warning.
If you already have an antivirus
Windows allows one antivirus to watch files at a time. If you have Quick Heal, Net Protector or anything else installed and active, Windows steps Microsoft Defender aside and that product does the protecting. My PC Doctor names whichever product Windows is relying on, leaves it alone, and never offers to remove it. The one case it will point out is a product whose licence has expired: those often keep Defender switched off, which leaves the PC with neither.
Common questions
Does My PC Doctor replace my antivirus?
No. It has no scanning engine and never will. It reads and manages the protection Windows already has, and can start Microsoft Defender own scan.
Does the Shield send anything to the internet?
The Shield page itself sends nothing. Checking a website contacts that one site for its certificate; checking a download reads the file on the PC and computes its checksum locally. No file is ever uploaded.
Is there cloud threat intelligence?
Not today. The product has a provider seam for it, but no reputation service is configured, so the app says nothing is known either way rather than showing a verdict it does not have.
