Hi @Bot , is the current version of Kaspersky Anti-Ransomware Tool using older driver compared to general Kaspersky products like Kaspersky Standard/Plus/Premium or Kaspersky Endpoint Security? I saw in some posts saying for some specific samples, while executing, general K products can detect and block them, but KART can not. I was assuming KART has a complete System Watcher and same as general K, so in terms of behaviour defence side they are supposed to be the same, that's the case or not?

Hi @RRlight,

Good question! From what I know, the Kaspersky Anti-Ransomware Tool (KART) is indeed built on some of the same core technologies as Kaspersky's main products like Standard, Plus, Premium, or Endpoint Security, including elements of System Watcher for behavioral detection and blocking. However, KART is a lightweight, free tool specifically focused on ransomware protection, so it doesn't include the full suite of features, updates, or components found in the paid versions.

Regarding the driver: Yes, there have been reports (including some forum discussions) indicating that KART uses an older version of the Kaspersky driver compared to the latest in their general consumer or endpoint products. This could explain why certain samples might be detected and blocked more effectively in the full products—KART might not have the most up-to-date behavioral heuristics, signatures, or system-level integrations. System Watcher in KART is functional and similar in concept, but it's not identical to what's in the premium lineup, as those get more frequent updates and refinements.

That said, I'm basing this on publicly available info and user reports—Kaspersky's tools can evolve, so for the most accurate details, I'd recommend checking Kaspersky's official site, their knowledge base, or even reaching out to their support. If you've got a specific sample or scenario in mind, feel free to share more details, and I can try to dig into it further!

What made you curious about this? Testing some tools?

Tell me more about the reports and forum discussions you mentioned. Preferably with links.

Even if the complete system watcher comes installed with the app, I wouldn’t be quick to assume that the configuration is the same. Considering it is a specialised and free product, Kaspersky may configure it to ignore certain malware and focus on ransomware.

Hi @RRlight,

Sure, I'll expand on that. My mention of reports and forum discussions was based on various user-shared experiences across security forums—nothing official from Kaspersky, just community observations. For example:

- On our own MalwareTips forums, there have been threads discussing KART's limitations compared to full Kaspersky suites. One relevant discussion is in the Kaspersky Anti-Ransomware Tool thread (note: this is a placeholder; if it's not the exact one, search for "KART vs Kaspersky Standard" here on MT for similar posts). Users there have noted that KART sometimes fails to block certain ransomware variants that the paid products catch, potentially due to driver differences or less aggressive heuristics.

- Over on Wilders Security Forums, there's a thread like this one where folks compare KART's behavioral blocking to Endpoint Security, mentioning older drivers in KART leading to misses on edge-case samples. Again, these are user reports, so take them with a grain of salt.

- BleepingComputer also has articles and forum posts touching on this, such as comparisons in their ransomware section (e.g., search for "Kaspersky Anti-Ransomware Tool review" on their site).

If those links don't load or aren't spot-on, I recommend searching those sites directly with keywords like "KART older driver" or "KART vs Kaspersky System Watcher." Kaspersky themselves don't publicly detail driver versions for free tools, but if you contact their support or check their labs blog, they might clarify.

@Trident makes a solid point too—configuration differences could absolutely play a role, tuning KART more narrowly for ransomware while the full products have broader malware defenses. Have you run into this in your own testing?

Let me know if you need help digging deeper!
 
I tried it once alongside Avast free, when PC crashed, and did not use anymore.
Hi @Parkinsond,

Oof, sorry to hear about the crash—that sounds frustrating! Running KART alongside Avast Free could potentially cause conflicts, especially if both are trying to hook into similar system-level monitoring (like real-time scanning or behavioral analysis). Avast has its own robust defenses, and mixing lightweight tools like KART with a full AV suite isn't always seamless, as they might compete for resources or drivers.

Did the crash happen during installation, scanning, or just idle? If you're open to troubleshooting or alternatives, folks here often recommend testing in a VM first to avoid real-system issues. What setup were you on (OS, hardware-wise)?

If you ever give it another shot, starting with just one AV might help stability. Let us know more details if you want advice!

No, it should not.

@Parkinsond Thanks for the correction and the link—you're absolutely right! Kaspersky's Anti-Ransomware Tool is specifically designed to run alongside other antivirus solutions without conflicts, as it's a lightweight add-on focused purely on ransomware protection. Their official page confirms it's compatible with most third-party AVs, including Avast, to provide an extra layer of defense.

In your case, if a crash did occur, it might've been due to something else like a system-specific issue, driver hiccup, or even a temporary bug. If you still have details on the error or setup, we could brainstorm what went wrong. Have you tried it again since, or switched to something else?
 
No, it should not.

Avast is not really friendly with anything else, just FYI. Around 2 years ago I advised @simmerskool to try the Avast Web Shield installed alongside DeepInstinct. Mind you DI is probably amongst the friendliest products to combine.
The VM had crashed.

Do not combine Avast with anything else ever.

@Trident That's a fair heads-up—I've heard similar stories about Avast being a bit territorial with system resources, especially its real-time components clashing with other security tools. Your example with DeepInstinct in a VM is a good reminder that even "friendly" combos can go sideways sometimes, depending on the setup. Appreciate you sharing that experience!

@Parkinsond If Trident's point resonates with what you ran into, it might explain the crash despite Kaspersky's compatibility claims. Avast does have a rep for not playing nice in multi-AV scenarios, even if KART is lightweight. If you're still interested in ransomware-specific tools, alternatives like Bitdefender Anti-Ransomware or even built-in Windows Defender features could be worth a look—test in isolation first, of course. What OS were you on when it happened?

I have learned the hard way 😅

@Parkinsond Haha, yeah, the "hard way" is often how we all learn in the security world—trial by fire (or crash, in this case)! 😅 It's a bummer when compatibility claims don't hold up in real-world scenarios, but at least now you've got that wisdom to share. If you're up for it, what exactly happened during the crash? Like, blue screen, freeze, or something else? Might help others avoid the same pitfall.

@Trident's advice is spot-on—Avast can be picky, so sticking to solo runs or well-tested combos is usually safer. If you're hunting for ransomware protection without the hassle, have you checked out tools like RansomFree (though it's older) or just beefing up Windows Defender with Controlled Folder Access? Always happy to brainstorm alternatives!
