I’m happy it can help you.

If necessary, I can do other tests.

Don’t hesitate.

Sincerely.

Just try it with the latest version, 4.1.319. The untestable file count in XML report should drop to zero.

Thanks

Hello,

Just tested c:\windows with the latest version.

Result : no more “files not tested due to an error”.

I’ve scanned with “standard scan” :

  • number of opened files : 19943
  • number of tested files : 19906
  • number of tested folders : 440
  • number of infected files : 0

In report, a lot of [E] File was skipped because of scanner settings (42016)
I can’t tell exactly the number, but hundreds.

With “thorough” scan :

  • same results, except infected files : 3

In report, no more errors, but 12 messages telling me that the file is in use, avast couldn’t scan it.

I don’t understand the result for “standard” scan :
it’s the same than “thorough” scan ( excepted infected files ) and there’s a lot of skipped files : error 42016.

Can you give me explain me why ?

Sincerely.

About infected files :

C:\WINDOWS\System32\ActiveScan\imscan.dll
[L]Win32:Kuang2 (0)

C:\WINDOWS\System32\ActiveScan\pav.sig
[L]Win95:Matyas (0)

C:\WINDOWS\System32\pav.sig
[L]Win95:Matyas (0)

When trying to repair the files :

  • no messages for imscan.dll but when trying to scan only this file, it’s always infected.

  • for the 2 .sig files : a message tells me that the file is not repaired. Cannot process file.

I don’t understand :

  • why the .dll still remains infected because there’s no message when I tried to repair it

  • why it’s not possible to repair .sig files : no information.

Can you help me ?

They cannot be repaired, because no record for an “uninfected” version is present in VRBD database.
Anyway, these files are from some Panda antivirus/tool and they are known false alarms caused by Panda not encrypting their virus signatures.

26

Techie, is this why you do not recommend Panda? ;D

27

Technical,

Yes, among other reasons. Since Panda does not choose to encrypt its’ signatures as Igor stated, it causes false alarms which can cause a user to delete needed files worsening the situation.

To me, this is a major negative for any piece of software, and I will not use it. I have also had some operational problems, instablity and such.
I also refuse to use Panda since it chooses to install a utility program on my hard-drive to perform the scan.
That is another quirk I have…I don’t let vendors remotely install anything that then feeds information out of my computer. Call me paranoid if you wish.
I have found Kaspersky online better and I only use it to confirm “an infection”.

Maybe Panda doesn’t like me. ;D

I don’t use Panda ; can I delete the .sig files without any problem ?

Thank you for all.

Yes, I think you can delete them.

I wish everybody a Merry Christmas
