Remove lines of "skipped" files from log

[hedoc]

Hi guys!
I'm using the KAV 2014 to scan my malware collection.
I pretend only scan the files and save a log file.
For that I created a bat file with the following line:

avp.com SCAN /i0 /fa /R:log.txt "F:\CollectionFolder"

It works perfectly but, for all infected and skipped file, the kav adds a line in the log file, for example:

...
2016-09-24 10:56:20 F:\VX\0\00\00081f6990f4102e46665ad838586e00 suspicion HEUR:Trojan.Win32.Generic
2016-09-24 10:56:20 F:\VX\0\00\00081f6990f4102e46665ad838586e00 skipped
2016-09-24 10:56:21 F:\VX\0\00\00082cd9eb6f953e1deef8aa393177b5 detected Trojan.Win32.Obfuscated.gen
2016-09-24 10:56:21 F:\VX\0\00\00082cd9eb6f953e1deef8aa393177b5 skipped
...

As you can see, for each infected file there is another line for "skip". Because of this, the log file will have almost twice the size and it makes the scan process slowdown a little, since it will request twice for write in disk.

I would like to know if anyone knows how to avoid that "skipped" line. Of course I could write a Python script for remove that but, I want to KAV creates a clean log as possible.

thanks in advance.
