Sure, does't hurt.

If you want, I can PM you the diagnostic report of my CCAV. May it will help?

today, I tried to uninstall CCAV to make a clean install..
Uninstallation stuck at 59% 

I cannot uninstall it now, it asked me to contact with support team. I am in trouble 
Can you please send me a script file which deletes all entries of CCAV? It will be our force uninstaller!

[megaherz33]

Just removed CCAV without problems

umesh,

A user on MalwareTips mentioned -
"If you rename the executable shortcut, on the next or any successive boot, it will detect problems in its own installation and one needs to reinstall. Fixing otherwise (as it advises) doesn't work."

You might try to re-store via System Restore to state prior to installation of CCAV.

Thanks Yash Khan,
If you change shortcut name, it doesn't have any impact as target application remains the same and CCAV is not going to show you any errors for that.

If you try to re-name executable e.g. ccavsrv.exe, it won't allow as it has self-protection.

May be check with him what OS he has and steps he took to rename the executable.

Thanks

Hi yigido,
It's a complex case. The behavior you observed is due to Valkyrie causing false-positive on that file, however Valkyrie web page as you pointed in link was not updated so you observed Unknown in there. At the moment file's verdict is Safe.

So that explains the behavior you observed.

Thank you for pointing out.

(Valkyrie result is "Unknown" but there is a detection in CCAV 1.9)
How is this possible?

I can also observed that..

I have a malware on my desktop on CCAV scan, it is not detected.
But I checked on Valkyrie website, Valkyrie verdict is "Malware.
There is no detection on my side.

What is the problem here?

[Umesh]

There are certain verdicts, which require human analysis before they are available in cloud.
That could be the case.

If every sample needs a human verdict, whats the point of Valkyrie automatic verdict 

[Umesh]

Not for every sample.
This is how automatic systems are improved, you trust few and you don't trust other till you are fully confident in automatic verdicts.

Valkyrie team is consistently working on improving so that more automated verdicts can be trusted and be available in cloud.
