Please drop Egemen a PM on this.
Do you have any idea with what 'tools/software' you have touched these files?
I have copied those samples from an external drive to my desktop. Besides, I have zipped them using 7zip and unzipped again too. so probably, explorer.exe and 7zfm.exe are the only two sw touching those files.
I think that both these are trusted.
I already waited for three days for someone to respond, but, Since now I cleared my trusted files list, I have to wait the issue reoccurs, so that I call EGEMEN for direct help.
