File scan
Quick, full, or custom-folder scans. Detects known-malware hashes, the EICAR test signature, and heuristics like executables hiding in temp and downloads. Uses ClamAV too if installed.

What Bolt does
Real protection, no bloat.
Everything you need to see and stop threats, and nothing you do not. Here is exactly what Bolt does.
System scan
Finds how malware actually hides: startup persistence, suspicious processes running from temp or downloads, and network listeners exposed beyond your own machine.
Security score
A clear 0 to 100 dashboard gauge, weighted by severity, so you know at a glance where your machine stands and whether it is improving.
Quarantine
Reversible isolation. Threats move to a managed store, so you can restore a false positive or delete it permanently. Nothing is destroyed without your say.
Real-time folder monitoring
Watches the folders you choose and flags or quarantines threats as files land, so downloads are checked the moment they arrive.
Verified auto-updates
Bolt checks for new versions on launch and installs them only after verifying the download's SHA-256. Never silent, never unverified.
How it works
Download, install, scan.
01
Download
Get the free installer for Windows, straight from sudowave.com. About 25 MB.
02
Install
Run the installer. If Windows SmartScreen appears, click More info then Run anyway (see the note below).
03
Scan
Open Bolt and run a scan. Read your security score and act on whatever it flags.
About the SmartScreen warning. Bolt is a new publisher still building download reputation, so Windows may show "Windows protected your PC." This is not a sign the file is unsafe. Click More info then Run anyway, and if you want to be certain, verify the SHA-256 below first.
Security and privacy
Built to be trusted.
Downloads are served over HTTPS from sudowave.com, updates are verified before they run, quarantine is always reversible, and no telemetry is required to use Bolt.
Verify your download
File: Bolt-Setup.exe
In Windows PowerShell, run Get-FileHash .\Bolt-Setup.exe and compare it to the sha256 value in latest.json, which always matches the current release.
System requirements
Runs light, everywhere.
- Windows 10 or 11, 64-bit
- macOS 11 or later (Intel or Apple Silicon)
- 64-bit Linux (glibc-based distributions)
- No account, no sign-up, no telemetry required
Windows is available now. macOS and Linux downloads go live once published to sudowave.com.
Honest about scope
What Bolt is, and is not.
Bolt does on-demand and scheduled scanning, plus real-time folder monitoring. It is not a kernel-level always-on shield, and we will never pretend it is. It pairs well with Windows Defender by adding scanning and system-threat visibility on top.
Common questions
Good to know.
Is Bolt free?
Yes. Download and use it free, with no account and no sign-up.
Do I need an account?
No. There is nothing to register and no email required.
Why does Windows warn me?
SmartScreen reputation for a new publisher. Click More info then Run anyway, and verify the SHA-256 if you like.
Does it replace Defender?
It complements on-demand scanning and adds system-threat visibility. It is not an always-on kernel shield.
How do updates work?
Bolt checks on launch and installs only after verifying the download. Nothing installs silently or unverified.
How do I uninstall?
Windows Settings, then Apps, then Bolt, then Uninstall.
