Advice Request Cannot connect to the KSN

[Didie Farhan]

I often get "could not get information from Kaspersky Security Network" when I want to check software with "check reputation in KSN". Kaspersky also cannot detect cloudcar from amtso. How to fix this.
Kaspersky Internet Security 2018 18.0.0.405(c)
Windows 10

Where do You come from? are You ISP working fine? any others security tools/applications installed in system?

 

[Didie Farhan]

I am from Malaysia.
How can i know whether an ISP is working fine? I already tested with two different ISPs.
The installed programs are voodooshield, adguard and malwarebytes free.
However i also have a couple of portable programs such as emsisosft, eset, hitman pro and zemana.

Adguard stand alone application I guess... some users using (AG + Kaspersky) are getting issues sometimes, try disabling temporally AG services...

If you have a vpn client try to connect with it to Kaspersky Lab

The installed programs are voodooshield, adguard and malwarebytes free.
However i also have a couple of portable programs such as emsisosft, eset, hitman pro and zemana.

Try to disable voodooshield to check if it connects. In my opinion too many security programs on your PC: Kaspersky, voodooshield, malwarebytes, emsisoft, eset, hitman, zemana

Most likely, the problem is due to VoodooShield or Adguard.
temporarily remove one product and watch.
Start with Adguard.
If you do not want to delete, as an option, you can disable the WFP driver in Adguard

If your ISP does its own filtering, that might be the reason. I had that problem in the past.

If you're using the desktop version of Adguard try updating to the latest beta version. They solved most issues with Kaspersky and Eset.

Does it related to Adguard since it only occurred frequently during peak hour whereas its working find during non-peak hour like in the morning. By the way, the internet speed is constant at 3Mbps during non-peak and off-peak hour during the time of testing.

If your ISP does its own filtering, that might be the reason. I had that problem in the past.

May i know how to determine whether an ISP used their own filtering? By using VPN?

It may be Adguard(Desktop version). I noticed some issues with Eset. Pc slowdown. Browsers crashing. Inability to terminate browsers processes, and needing a computer restart.

Adguard desktop, I had to uninstall it to the heavy navigation, and apart used lots of ram.

 

[Didie Farhan]

I uninstalled Adguard and the error seems gone for now. Thank you for everyones help. I will update later if the error occur again.

Good to know.

Just an FYI, whenever this happens to me, occasionally, i update my Kaspersky database & the error goes away after a successful update even if there are no available updates. Well this is just me, your seems like a different problem. Just a suggestion as i also use Adguard desktop & Kaspersky together.

Regards.
