8 Best Windows Privacy and Security Tools in 2026

Security software is sold as one thing and it is really five, and buying the wrong one is how people end up paying a subscription for protection they already had.

Hold your secrets. A password vault, and whether a company holds it or you do. KeePassXC.

Make the disk unreadable. For the laptop that gets left in a taxi. VeraCrypt.

Delete what Windows keeps. Logs, caches, histories and thumbnails that accumulate whether you want them or not. BleachBit.

Hide the connection. Two VPNs with very different funding models, which is the only thing that matters about a VPN. ProtonVPN, Hotspot Shield.

Catch the malware. With an honest note about what Windows already does. Malwarebytes, Panda Dome.

And one specialist tool that does not fit any of those, and is on the shelf because it is genuinely used by a profession. AdsPower.

The first three are open source, free, and the highest-rated tools here. That ordering is not an accident.

Every version, size, minimum Windows and licence below is the catalogue entry for the package this site serves.

Hold your secrets

1. KeePassXC — the vault nobody else holds

KeePassXC is the highest-rated tool on this page, and its whole design is the absence of a company.

• Version: v2.7.12 · Size: 63.9 MB · Windows: 11 / 10 · Licence: open source · Developer: KeePassXC Team (Open Source)

Passwords, notes, attachments and TOTP codes in an encrypted database file that sits wherever you choose to put it — a local folder, your own cloud, a USB stick. Browser integration, a password generator, and no account, no subscription and no server. At 4.9★ across 34,100 reviews it is the best-rated tool here, and the source is public and has been audited.

The trade is that sync and backup are entirely yours. There is no company to recover a lost vault, and a corrupted database file with no backup is a permanent loss. Put the file somewhere that is already backed up and this becomes a non-issue.

Pick this one if: you want a password manager with nobody in the middle, and you will keep a backup of one file.

Make the disk unreadable

2. VeraCrypt — full disk and container encryption

VeraCrypt is the answer to the specific question "what if someone else gets the drive?"

• Version: v1.26.14 · Size: 24.6 MB · Windows: 11 / 10 / 7 · Licence: open source · Developer: IDRIX (Open Source)

It encrypts an entire system drive, a partition, a USB stick, or a single container file you mount like a drive letter. It is the maintained successor to TrueCrypt, it is open source, and it has been through independent audit. At 4.9★ across 26,500 reviews it is the standard free answer for Windows, and it is 24.6 MB.

The trade is absolute and worth stating twice: if you forget the password, the data is gone. There is no recovery, no reset, no support line — that is the entire point of the thing. Full-system encryption also adds a boot-time password and a small performance cost.

Pick this one if: you carry a laptop or a USB stick with anything on it you would not want a stranger reading.

Delete what Windows keeps

3. BleachBit — the cleaner that actually deletes

BleachBit is 13.2 MB and it is the open-source answer in a category full of paid "optimisers".

• Version: v4.6.0 · Size: 13.2 MB · Windows: 11 / 10 / 7 · Licence: open source · Developer: BleachBit Project (Open Source)

It clears caches, logs, temporary files, browser histories and application traces across hundreds of programs, frees real disk space, and can overwrite free space to make deleted files harder to recover. At 4.8★ across 15,400 reviews it is well trusted, and there is no upsell anywhere in it.

Two honest caveats. It is thorough enough to delete things you wanted — browser sessions, saved form data — so read the checkboxes rather than selecting everything. And free-space overwriting is far less meaningful on an SSD than on a spinning disk, because of how SSDs manage blocks internally.

Pick this one if: you want a cleaner with no subscription attached and you will read what it proposes to remove.

Hide the connection

4. ProtonVPN — the free tier that is not funded by you

ProtonVPN is the rare free VPN whose business model is visible.

• Version: v5.1.5 · Size: 122.8 MB · Windows: 11 / 10 · Licence: freeware · Developer: Proton AG (Freeware)

A free tier with no data cap at all, from a Swiss company operating under Swiss privacy law, with independently audited code and a published no-logs position. Paid subscribers fund the free tier, which is the answer to "how is this free". At 4.8★ across 62,400 reviews it is the best-rated VPN here.

The trade is that the free tier limits you to a handful of countries, one device, and slower speeds at busy times, and it will not get you into streaming catalogues. At 122.8 MB it is also a heavy client. For everyday privacy on untrusted Wi-Fi it is the one to use.

Pick this one if: you want a free VPN and you want to know who is paying for it.

5. Hotspot Shield — the big commercial one

Hotspot Shield has by far the largest audience on this page and the lowest rating on it.

• Version: 12.7.2 · Size: 45 MB · Windows: 10 / 11 (64-bit) · Licence: freeware · Developer: Aura / AnchorFree Inc.

Its proprietary Hydra protocol is genuinely fast — speed is the pitch and it delivers on it — with 256-bit AES encryption and a light 45 MB client. At 4.6★ across 1,850,000 reviews it is the most-used tool here by a factor of twenty, and the least well rated.

The trade is the free tier, which is limited and advertising-supported, and the gap between "encrypted" and "private". A commercial VPN sees the traffic your internet provider used to see. If the reason you want a VPN is privacy rather than speed, read the provider's policies before the marketing.

Pick this one if: you want raw speed on a public network and you are comparing paid plans rather than relying on the free tier.

Catch the malware

6. Malwarebytes — the second opinion

Malwarebytes is 18.4 MB and it is the tool to reach for when a machine is already misbehaving.

• Version: v5.1.7 · Size: 18.4 MB · Windows: 11 / 10 / 7 · Licence: freeware · Developer: Malwarebytes Inc. (Freeware)

It specialises in the things traditional antivirus tends to shrug at: adware, browser hijackers, toolbars, and potentially unwanted programs bundled with something you installed on purpose. Its on-demand scan is fast and it does not fight with Windows Defender. At 4.8★ across 82,000 reviews it is widely trusted for exactly this role.

The trade is that the free version is an on-demand scanner — real-time protection is the paid tier, offered as a trial that expires. That is fine, because the on-demand scan is the useful part and Defender is already handling real time.

Pick this one if: something is wrong — pop-ups, a changed search engine, a browser that will not behave — and you want a second opinion.

7. Panda Dome Free — the light cloud scanner

Panda Dome Free is the full antivirus option here, and its distinguishing feature is where the work happens.

• Version: 22.00.01 · Size: 75 MB · Windows: 10 / 11 (64-bit) · Licence: freeware · Developer: Panda Security / WatchGuard

Detection runs largely in the cloud, so the resource cost on the PC is very low, and it includes USB vaccination — disabling autorun on thumb drives so a plugged-in stick cannot launch anything by itself. It also bundles a limited free VPN. At 4.7★ across 920,000 reviews it has a very large user base.

The trade is the one this whole category carries in 2026: Windows Defender is already good, already installed and already updated, and adding a second real-time scanner buys you upsell prompts more reliably than it buys you safety. Cloud detection also means less protection when offline.

Pick this one if: you specifically want a third-party real-time scanner and you value low resource use — otherwise keep Defender.

The specialist

8. AdsPower — the multi-account browser

AdsPower is on this shelf because it is a real professional tool, and it needs explaining rather than recommending.

• Version: 7.3.26 · Size: 168 MB · Windows: 10 / 11 64-bit · Licence: freeware · Developer: AdsPower Software

It runs many isolated browser profiles side by side, each with its own cookies, storage and configurable fingerprint — user agent, canvas, WebGL, audio — across two engines, a Chromium-based one and a Firefox-based one. The legitimate audience is agencies and sellers who genuinely operate many separate accounts: a marketing agency running ad accounts for thirty clients, an e-commerce seller with storefronts in several regions.

The trade is that platforms treat multiple accounts under their own terms of service, and fingerprint separation does not change what those terms say. It is also 168 MB, the largest install here, and it is a business tool with business pricing behind the free tier — there is nothing in it for someone managing one of anything.

Pick this one if: managing many separate client or storefront accounts is your actual job.

The eight, side by side

What none of these fix

A VPN is not anonymity. It moves your traffic's visibility from your internet provider to the VPN company. That is a genuine improvement on hostile Wi-Fi and it is not the same as being unidentifiable.

Encryption protects a powered-off machine. VeraCrypt makes a stolen drive unreadable. While Windows is running and the volume is mounted, the files are just files.

You probably do not need a third antivirus. Defender is good, free and already running. A second real-time scanner mostly adds prompts, and running two at once slows the PC.

Wiping free space on an SSD does less than it claims. SSD wear levelling means overwriting a logical block does not reliably overwrite the physical one. For a drive you are disposing of, full-disk encryption from the start is the answer, not a wipe at the end.

The two-minute version

Start with the three free, open-source ones: KeePassXC for passwords, VeraCrypt for the disk, BleachBit for the leftovers.

Public Wi-Fi? ProtonVPN — the free tier has no data cap and the funding is visible.

Something already wrong with the PC? Malwarebytes, on-demand scan, alongside Defender rather than instead of it.

Antivirus? Keep Windows Defender. Panda Dome only if you specifically want to replace it.

Every app named here resolves to a page in the FileCobra catalogue — the build fails if one does not. Versions, package sizes and system requirements are read from that catalogue rather than written by hand. Where our ingestion worker has fetched a release itself, it records a SHA-256 of the exact file we serve and publishes it on the app’s page. We do not run an antivirus lab: where a VirusTotal report exists we link it, and where none exists we say so rather than imply one.
