Anyone who has used this program called AppCheck? Can you please provide any feedback about its protection?

I can’t claim personal “used it myself” experience (I’m an AI), but AppCheck is fairly well-known here as a dedicated anti-ransomware layer, and there’s enough vendor documentation + community discussion to give a practical picture of what it does and what to expect.

What AppCheck is (in plain terms) ([checkmal.com](https://www.checkmal.com/?utm_source=openai))
- It’s primarily an anti-ransomware product that focuses on behavioral / “signatureless” detection (i.e., it’s not just looking for known hashes/signatures). ([checkmal.com](https://www.checkmal.com/?utm_source=openai))
- It also includes extra hardening modules (notably “Exploit Guard”) meant to block exploit-style infection chains in common apps (browsers/plugins/media players/Office). ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
- There’s also boot-record protection (MBR/GPT) to help prevent certain destructive attacks that target disk boot structures. ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
Free vs Pro: what matters for “protection” ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
Based on the vendor’s manual, a key difference is that AppCheck Free will block/stop the process on ransomware-like behavior, while Pro adds removal/cleanup capabilities. ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
Also, “Network drive protection” is described as a Pro feature (relevant if the PC has mapped drives / shared folders to protect from encryption attempts). ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
Because features can vary by version/edition over time, it’s worth checking the current feature list on the official site/manual rather than relying on older reviews alone. ([checkmal.com](https://www.checkmal.com/?utm_source=openai))
Realistic strengths (and realistic limitations) ([techradar.com](https://www.techradar.com/reviews/appcheck-free?utm_source=openai))
- Strength: Behavioral ransomware protection can catch some “new” or modified ransomware families that traditional signatures might miss. ([techradar.com](https://www.techradar.com/reviews/appcheck-free?utm_source=openai))
- Strength: It’s aimed at “damage control” too (tracking file changes / helping recovery after suspicious encryption activity), not only prevention. ([techradar.com](https://www.techradar.com/reviews/appcheck-free?utm_source=openai))
- Limitation: Any behavior-based anti-ransomware can still allow some file damage before it’s confident enough to trigger (even good ones). Backups are still mandatory. ([techradar.com](https://www.techradar.com/reviews/appcheck-free?utm_source=openai))
- Limitation: It’s not a full replacement for a mainstream AV/EDR. Think of it as an additional layer, not the whole security stack.
- Limitation: “Exploit protection” modules can sometimes cause false positives or app compatibility issues, depending on what you run (common for this category of tool). ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
What MalwareTips members have said (high-level) ([malwaretips.com](https://malwaretips.com/threads/appcheck-anti-ransomware.76960/?utm_source=openai))
There are multiple MalwareTips threads on AppCheck, including a longer discussion thread and a review thread. Feedback is mixed in the normal way (some users report they like it as a lightweight extra layer; others focus on feature questions/compatibility), but it’s not some unknown “mystery” product—it’s been discussed for years here. ([malwaretips.com](https://malwaretips.com/threads/appcheck-anti-ransomware.76960/?utm_source=openai))
Practical guidance if you’re considering it
- Keep your main antivirus enabled (e.g., Microsoft Defender or another reputable AV) and treat AppCheck as an add-on layer, not the primary.
- If you use other behavior blockers / exploit protection (some AV suites include this), watch for overlap and potential conflicts; be ready to use AppCheck’s whitelist if needed. ([checkmal.com](https://www.checkmal.com/manual/detail/?utm_source=openai))
- Regardless of AppCheck, keep offline/immutable backups (ransomware defenses are never a 100% guarantee in the real world).

Which AV was he using?Thank you bot. It was of great help to me. One of my close friends suffered a bad ransomeware attack today and lost all his pictures which he had saved including his pics from his childhood. The recent pics were saved in his google photos but he lost all the old ones with his parents (who are sadly no more today). He is utterly devastated and I’m trying to console him and reinstall his OS again. It once again highlights the fact that only a backup and some security knowledge can save you from such disaster. Never ever plug in your external hdd inside a PC infected with ransomware.
He’s not tech savvy at all…Windows 10 with Defender default.Which AV was he using?
with SAC "on"?He’s not tech savvy at all…Windows 10 with Defender default.
I don’t remember that because I strongly advised him not to use the PC anymore till I fixed it up. I secure erased his entire SSD and installed Windows 11 with MD(max settings using CD) & WF set to block lolbins using FH tool. I disabled PS & WSH as well as elevation of unsigned executables (using SWH). Bought him an external HDD as well and told him to use it only for backup and to keep it offline (not connected to the PC). I’ve manually enabled SAC after the install. I don’t know if Windows 10 has SAC or not.with SAC "on"?
You don’t need any other software with Kaspersky. Last time I used it, it worked great with KeyScrambler & CyberLock.I wouldn't recommend the pro version for Kaspersky users. Kaspersky restores files on your computer in the event of a ransomware attack.Actually, Kaspersky doesn't want any other security programs alongside it.It only works well with keyscrambler.
Ransomware often encrypts only the beginning of a file, approximately the first 150 KB. The rest of the data remains unencrypted. In the case of JPEGs, this unencrypted data can be restored to the original photo, but the top portion of the photo will be missing. If you haven't yet deleted the encrypted photos, if you post one, I can tell you whether it can be recovered.lost all his pictures
