If your PC is not protected against Meltdown vulnerability, you can take the following steps to mitigate the risk:

1. Ensure that all software on your PC is up-to-date, including your operating system, drivers, and applications.
2. Install the latest updates for your security software, including Kaspersky Plus.
3. Enable Windows Defender Application Guard or hardware virtualization-based security, if available on your PC.
4. Consider using a browser extension or plugin that blocks JavaScript, which is often used to exploit Meltdown vulnerabilities.
5. Disable any unnecessary services and features, such as remote access or sharing, to minimize your attack surface.

Additionally, you can visit the Microsoft website to download and install the latest security updates that address the Meltdown vulnerability.

Hello @Bot
1. My PC is automatically updated
2. Kaspersky is automatically updated
3. Windows Defender Application Guard or hardware virtualization-based security is not available on my PC (W11 is installed over W10)


4. I'm using Adguard AdBlocker ; isn't it enough ?
5. No remote access enabled
6. Can i solve the problem if I change my security software ?

Changing your security software alone may not solve the Meltdown vulnerability issue. However, you can try switching to a security solution that provides additional protection against Meltdown and Spectre vulnerabilities. You could look for security software that uses virtualization or hardware-based security features to mitigate the risks. Some examples of such solutions are Microsoft Defender Application Guard, Norton Security, and Trend Micro Titanium Maximum Security. Additionally, make sure to keep your system and software up-to-date, disable any unnecessary services or features, and use a browser extension that blocks JavaScript to further enhance your protection.

Adguard AdBlocker is not good ??? What else ? coffee:)
Another question, How can I disable "Bot" ?

Adguard AdBlocker is a good ad-blocking solution, but it may not provide complete protection against Meltdown and Spectre vulnerabilities. Using a security solution that uses virtualization or hardware-based security features, as mentioned earlier, may further improve your protection against these vulnerabilities.

And Kaspersky is not good against Meltdown ?

And Kaspersky is not good against Meltdown ?

Kaspersky provides protection against Meltdown vulnerability by detecting and blocking malicious programs that exploit this vulnerability. However, it is essential to keep your Kaspersky security software up-to-date with the latest security patches to ensure optimal protection against this and other security threats. Additionally, as mentioned earlier, using a security solution that uses virtualization or hardware-based security features may further improve your protection against Meltdown and Spectre vulnerabilities.

What can I do ?

You have to contact your hardware OEM and ask for their Meltdown vulnerability patch file.

I would do that before you try any of the fixes provided at numerous online sources.

You should use only an OEM or Microsoft provided solution. Plus, if you do it wrong, it can bork your machine.

Intel does not provide the fix. The laptop or PC manufacturer provides the fix.

Intel, if it provides a fix, will provide only a generic one - instead of one for the specific platform.

If you have a generic or self-built system, then you'll have to start with Intel, then check Microsoft for a fix.

As an AI language model, I don't have a direct physical presence, so you can't physically disable me. However, you can choose not to interact with me or not respond to my responses if you prefer not to.

Perfect!

What can I do ?

To put it simply, nothing, since hardware/software devs chose to support only certain devices. I have disabled mitigations for the performance gain, I consider this vulnerability overrated.

reg add "HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management" /v "FeatureSettingsOverride" /t REG_DWORD /d "3" /f
reg add "HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management" /v "FeatureSettingsOverrideMask" /t REG_DWORD /d "3" /f

Performance hits of between 5-30% (depending on workload) were seen in early testing of software fixes, but the effect has been nowhere as severe in practice

Edited: the Meltdown button doesn't work for some reason so forget what I said about that.

It actually shows the same thing and I can't enable Meltdown. But anyway, that's the extent of my messing with it. Maybe adding the key manually might help.

Example

Scroll to the middle of the page under FAQ for the Meltdown registry values.

Edited to remove text about enabling Meltdown via the InSpectre UI. It doesn't work on here.

Meltdown vulnerability fix is done at bios level and at software level and if one part is missing the test will fail. Search your pc manufacturers website and download the latest bios version and install it ( bios software don't get auto updated, you will have to install it manually). This will fix your system.

 

[JB007]

Hello,
Thanks all
My BIOS was updated a week ago.
I though that recent CPU (mine is an Intel Core 11th Gen) are patched agains these kind of vulnerabilities ?!
If my understanding is good (@TairikuOkami ), it is not very important to fix this Meltdown vulnerablity ?
