Malware has a habit of slipping in through the side door. You install one “free” video converter, click one dodgy download button, and weeks later something’s redirecting your browser or quietly parked in your registry. Your main antivirus swears everything’s fine. That gap — between “my AV says I’m clean” and “then why is my PC acting weird?” — is exactly where a tool like Adlice Protect earns its place.

Running two full antivirus suites at once is a recipe for conflicts and a sluggish PC. But pairing one solid always-on antivirus with a lightweight, on-demand malware hunter you run every so often? That’s a genuinely smart setup — and it’s the setup Adlice Protect was built for. I’ve leaned on this tool since its RogueKiller days, so when the 2026 build landed I installed it fresh on my Windows 11 machine to see how it holds up.

From RogueKiller to Adlice Protect: what actually changed

If you haven’t touched this tool in a couple of years, the name swap can throw you. RogueKiller is now Adlice Protect — same developer (Adlice Software), same anti-rootkit heritage, but wrapped in a proper dashboard with Protection, Scan, History and Settings sections instead of the old bare-bones utility window. The detection side still leans on a signature list, and Adlice pairs that with AI and cloud lookups to flag unknown or behaving-badly software rather than only matching known fingerprints.

The build I tested reports itself as 16.8.3.0 with signatures dated mid-August 2026. Adlice ships updates at a genuinely rapid clip — several point releases a month isn’t unusual — which matters for a scanner whose whole job is catching what’s new. One thing worth setting expectations on: in the free version those signature updates are manual. You download them yourself from the Scan screen; the “install it and forget it” auto-updates are a Premium perk.

Getting to the free version (without accidentally paying)

Here’s the one bit of friction worth flagging up front. When you first launch Adlice Protect, it greets you with a Premium pitch and two shiny buttons — Go Premium and Activate Trial. The free route is the modest little link underneath: “Not Now, I will use Free Version.” Click that and you’re straight into the full free experience, no card required, no time bomb ticking. It’s not hidden, exactly, but it’s designed to be the path of least resistance toward the paid tier. Now you know where to look.

Three scan modes — and when to reach for each

The Scan screen keeps it refreshingly simple. You get three clearly labelled choices, and honestly that’s all a second-opinion scanner needs:

What a real scan looks like

During my Standard scan, the progress screen stayed genuinely useful rather than just spinning: live counts of scanned items, time elapsed, current file, and — the part that matters — a running tally of detections. It caught a batch of PUP.Outbyte entries (a potentially unwanted program), the kind of grey-area junk that a signature-only antivirus often shrugs at. My PC stayed perfectly usable throughout, which tracks with Adlice’s claim that it’s tuned to leave you enough horsepower to keep working, or gaming, mid-scan.

You’ll also notice a UCheck card on the scan screen listing “outdated programs.” That’s Adlice’s separate software-updater tool doing a bit of cross-promotion — outdated apps genuinely are a top attack vector, so the nudge isn’t wrong, but it’s an upsell, not part of the malware scan itself.

Reviewing and removing what it finds

When the scan wraps, you get a clean results list — each item with its name, full path (registry key, Start Menu folder, ProgramData folder, and so on), the detection label, and a status. Everything’s ticked for action by default, and there’s a “More information” expander per item if you want to understand what you’re about to delete. That transparency is important: you can see it caught the same Outbyte PUP across a registry key and two folders, so you’re removing the whole footprint, not just one visible piece.

From there, the free version lets you hit Removal to clean the selected threats, export a Report, or untick anything you’d rather keep (handy for a “PUP” you actually installed on purpose). This is the crux of the free tier’s value — it doesn’t just show you the problem and paywall the fix. It removes what it finds, for free.

Free vs Premium: what you’re actually giving up

Let’s be honest about the trade. The free version is a scanner. It only works when you tell it to. Everything that makes a security tool proactive lives behind the paywall. Here’s the split as it stands in 2026:

The Technician tier at $35/year is aimed squarely at repair-shop folks and IT support — it unlocks cleaning machines you don’t own, commercial use, and white-label rebranding. For a regular home user, that’s overkill; Personal at $15/year is the one to weigh if you decide you want the always-on shield.

Who should actually use it

Adlice Protect Free isn’t trying to be your everything. It’s the specialist you call in for a second opinion. Keep a proper real-time antivirus running as your front line, then let Adlice do a deep sweep once a week or whenever your gut says something’s off. That combo — one always-on shield plus one sharp on-demand hunter — is the setup I recommend to almost everyone who asks.

If you like this “layered” approach, you’re spoiled for free choice right now. Microsoft Safety Scanner and Trellix (McAfee) Stinger are two other excellent portable, on-demand cleaners that pair the same way. For the bigger picture, my roundup of 5 free tools to get rid of malware maps out how these pieces fit together.
