SiriusGPT + PCMatic

[annaegorov]

Well, I bought a lifetime license for SiriusGPT today. I didn't start the day with that intention.

I had the day off and was thinking about, what I would like to achieve with my clean install, and software protection... Could I keep it simple, fast, yet effective?

I have a lifetime license from 4 years ago for PCMatic, that I could use. I love the concept of default deny. But they don't have a firewall or strong signature defense, database, like Avast. However, I read that PCmatic works will all other security solutions.

Then as I was reading MWT posts today, I noticed several stating SiriusGPT, was light, and very effective at scanning, also that it could be used with any AV.

This led me to think, possibly Sirius could fill the gaps for PCMatic, by providing strong scans, similar to a strong signature AV, like Avast.

So, I installed both PCMatic and SiriusGPT, and started all my software apps, they all ran fine. PC and internet very responsive.

For my AMD PC, I would rate the response times to Eset, McAfee, or Avast One, possibly Sirius + PCMatic is even faster, certainly even.

This was several hours ago, I have tried some gaming, browsing, and even Netflix.... No problems or hiccups whatsoever. Did a complete scan of my PC all three drives C: / D: / E:

I haven't tried Cyberlock yet, as people made it sound like, at least in my mind, that Cyberlock was also default deny, and since PCmatic is default deny, that wouldn't be a good idea.

And people also said you can't install SiriusGPT with Cyberlock. Thus I used PCMatic instead. For the firewall I couldn't decide, so I stuck with Windows 11 firewall, figuring simple, or tiny, or even Zonealrm might complicate things, or even be bloat

I seem to be problem free, and everything is running nicely. 2 Lifetime Licenses makes this nice. Made a BU Image with Macrium. Good to go.

Sounds like you ended up with a setup that is both “light” and usable day-to-day, and the Macrium image afterward is exactly the right move.

I can’t verify specific compatibility claims about SiriusGPT vs CyberLock (or how SiriusGPT implements real-time protection vs on-demand scanning) without vendor documentation, so I’ll stick to the reliable “layering” principles that usually apply in Windows security setups.

1) The big picture: what you built (and what it’s good at)
PC Matic’s strength is the default-deny / application control approach (prevent unknowns from running). That can be very effective against new/unknown malware, and it often stays fast because it’s not trying to signature-scan every file all the time.

A second tool can make sense if it adds one of these:

• Strong on-demand scanning as a “second opinion”
• Better coverage for fileless/script threats, PUA/PUP cleanup, or email/web attack vectors
• Behavior blocking/anti-exploit (depending on the product)

If SiriusGPT is acting mainly as an additional scanner (especially on-demand or scheduled), that’s usually a low-conflict way to “fill gaps” without turning the system into a heavyweight suite.

2) Avoid stacking two “default-deny / anti-exe” products
Your instinct to avoid CyberLock on top of PC Matic is reasonable.

In general, running two products that both do application control / default-deny can cause:

• Duplicate prompts/blocks and confusing allow/deny decisions
• Conflicts at the driver/filter level (sometimes subtle)
• Higher chance of breaking games/launchers/anti-cheat updates

So “one default-deny + one scanner/AV-style layer” is usually the cleaner design.

3) Windows 11 Firewall is a sensible default
For most home users, Windows Firewall is already solid and low-risk. Third-party firewalls often add complexity, extra prompts, and sometimes network stack quirks, with limited real security gain unless you specifically need outbound control and are willing to manage rules.

If later you decide you want outbound prompts/control without replacing the firewall engine, a “front-end” that manages Windows Firewall rules is typically less intrusive than swapping in a full third-party firewall. (I’m not endorsing a specific one here since product quality and ownership changes over time.)

4) Practical hardening that pairs well with a light setup
These tend to give good security return with minimal performance cost:

• Keep Microsoft SmartScreen enabled (it’s still useful even if you don’t rely on Defender as your main AV).
• Make sure Windows Update, browser updates, and GPU/chipset drivers stay current.
• Enable/keep: UAC (not disabled), and consider “Memory integrity” (Core isolation) if it doesn’t break performance/anti-cheat on your system.
• Keep at least one reliable real-time layer active (whether that’s PC Matic’s protection, SiriusGPT’s real-time components if it has them, or Microsoft Defender if it’s left enabled). Avoid having multiple real-time engines fighting over the same events.

5) Your backup step is the real “win” here
The Macrium image is your best recovery tool if anything goes sideways (bad update, false positive, system corruption, ransomware, etc.). If possible, keep at least one backup copy offline/not constantly attached.

Bottom line
What you’re doing (one default-deny style product + a second scanning layer + Windows Firewall + a fresh image backup) is a defensible “simple, fast, effective” approach—provided you avoid stacking multiple default-deny/HIPS products and you ensure at least one competent real-time protection layer is actually active.

If you later run into a strange block, app launch issue, or network problem, the safest next step on MalwareTips is to post the exact alert/log details (product, timestamp, file path, and what was blocked) so members can tell whether it’s a normal default-deny event or a genuine conflict.

First, thank you for purchasing a lifetime license!

I do not want to dunk on other products, but my best advice would be to try PC Matic + SiriusGPT on AutoPilot or CyberLock on its own. You could also just do SiriusGPT on its own, if it is in Dynamic Security Posture mode instead of AutoPilot. I would just try different configurations until you find what works for you the best.

How do you like Pc Matic? Is its protection good? I'd appreciate it if you could write a review-style piece about it. Are lifetime memberships still being sold?

Well it is very nice, no ads, or popups, I don't even know it's there, same for Sirius.

PC still very fast, possibly even faster than Eset, going from memory Eset, Kaspersky, Avast One, and McAfee are very fast on my PC. PCMatic and Sirius are at least as fast possibly faster.

The cost for PCMatic for one year is 50 US dollars for 5 devices, that is 10.00 each.

Concerning the Lifetime License, this is what "Terms and Conditions" states below:

18. Lifetime License (aka Evergreen License)
18.1 A Lifetime perpetual license will allow the customer to use the licensed full version of the software indefinitely - for non-commercial purposes.

18.2 The Lifetime perpetual license is nontransferable.

18.3 The Lifetime perpetual license includes all future product and security updates.

The price is and I believe still is 150.00 dollars for the lifetime license and I am pretty sure it was for 5 devices. Please double check that lifetime purchase info before you buy.

For a professional review, possibly Shadowra could do this, and maybe those of us here who are members are MWT could chip in to cover the 50 dollars so he can test it, via maybe gofundme

You're welcome, glad to help. Somethings are worth paying for. That is also why I support Macrium. I checked that setting, it is auto, looks like that was default too.

Just so everyone understands, the zero trust components in PCMatic and VoodooSoft products are absolute polar opposites... they could not be more different. As I was saying, I do not want to dunk on a competitor, but I thought about it and decided it was best to provide some objective facts so that everyone understands PCMatic and our products are completely different products.

In your original post, you said... "I have a lifetime license from 4 years ago for PCMatic, that I could use. I love the concept of default deny. But they don't have a firewall or strong signature defense, database, like Avast."

Keep in mind that PCMatic's zero trust layer is a global whitelist that is managed by human malware analysts. Also keep in mind, several other cybersecurity vendors have very similar global whitelists, although they are utilized a little different between vendors. For example, PCMatic utilizes their global whitelist as the single source of truth for verdicts, whereas most other cybersecurity vendors that have global whitelists utilize them to auto allow known safe files, but they are not utilized as the single source of truth.

At the other end of the spectrum, VoodooSoft has a global whitelist as well, known as WhitelistCloud, but it is not managed 100% by human malware analysts, it is largely automated, which has advantages and disadvantages. But keep in mind, VoodooSoft's zero trust layer does not rely entirely on the global whitelist. In addition to WhitelistCloud, VoodooSoft's zero trust layer has many, many sophisticated efficacy and usability features that can best be described by viewing our comparison matrix here: CyberLock - Automated and Effortless Zero-Trust Endpoint Protection.

So both PCMatic and VoodooSoft zero trust implementations are completely valid, but they could not be more different, and really it all comes down to what works best for each user.

So, I just want to know, at my age, that I am comprehending and understanding what you wrote, in summary:

1). Both products are different, even though they have a similar task, which is a global whitelist, that they use differently.

2). There is nothing wrong with PCMatic, you can safely use it if you choose to do so. Also, there is nothing wrong with Voodoosoft, you can safely use it if you choose, it's up to personal choice.

Did I get that right?

 

[danb]

1) No, PCMatic utilizes a larger shared simple global whitelist, our products utilize a tiny local whitelist that is automatically customized to each endpoint / computer.

2) Yes, both are perfectly valid options. I really think it is best to try each one and see which one works best for you.

Just keep in mind there are tons of other differences between the two other than what whitelisting tech it uses. For example, Sirius, and most of the other features listed in our comparison matrix.
