Windows Update kb2507938 TrojWare.Win32.Trojan.Katusha?

Unfortunately, I am still having the same problem installing KB2507938. I've updated Comodo's definitions and I'm still getting a TrojWare.Win32.Trojan.Katusha warning.

Additionally, I have discovered another update from Microsoft that is causing the same problem: KB2533623. Anyone else encountering issues when installing this update from Microsoft?

I am having the same problem with KB2533623 as I did with KB2507938, with Windows 7, Home Premium, 32 bit. This morning I tried to install KB2507938, and, each time the Comodo alert came up, I chose "Ignore - once" (It popped up about 10 times). When it was done, Windows Update said that the update had installed correctly. I know I took a chance in doing it that way, but figured if it came from MS, it had to be a false positive, since others I know who installed it, and were not running Comodo, did not have a problem.

Hi everyone,

We isolated the issue where some legitimate files were detected as TrojWare.Win32.Trojan.Katusha.~E. An update was released and the fix is now live. Anyone who encountered any issues related to this detection, please update the CIS virus database to version 9392.

Thanks and regards,

Thanks for the quick work on this! Does the update account for both KB2507938 and KB2533623?

Hi,

The fix is available for both updates.

What will happen with those running just the Firewall and Defense + modules where the installation is still blocked?

[EricJH]

See if it is in Unrecognised Files and remove it from there when found. Also check the D+ logs (View Defense + Events) to see if it show blocking.

[rossall]

It is not in unrecognised files and there is no record of it being blocked by D+.

The updates still fail with Firewall and Defense + completely disabled.

After restarting I get the Windows error message 'failed to configure updates', then it restarts again and reverts the changes.

What Windows version are you on? Did you disable D+ using Deactivate Defense+ permanently(Requires a system restart)?

What Windows version are you on?

I am using Windows 7 Home Premium English (UK) 32 bit.

Thanks, I just tried your suggestion and it works!

Don't forget to switch D+ back on after updating Windows. If the next rounds of Windows updates give you a hard time please open a topic and we will look deeper into it.
