Kaspersky Antivirus uses a method called iChecker (for FAT32 partitions) and iStreams (for NTFS partitions) to remember the files it has scanned. It somehow tags the files it has scanned with some data. I found this recently when trying to transfer a file from my hard-drive to the USB drive and encountered a message
Thinking it to be a virus infection I did thorough AVG 7 (Free) scan but nothing. And then KAV recalled Kaspersky antivirus to my mind that I had uninstalled a long time ago.
The found this out on Kaspersky Online FAQ
I don't even remember the KAV uninstaller asking me whether to keep this information or not. Why?
Then, as instructed I downloaded their Klstreamremover.exe utility ("can clean ADS tags of files") and ran it from command line with -r as told. It said "Total Streams found 3116, w/o stream 10". Not very helpful. So I try to transfer the file to USB drive again and same crap happening. Why... why... why...?
This is very annoying. Somebody please help me get rid of this crap irrespective of whether its harmful or useful. Are there other antivirus/antispywares using this same trick?
.The file 'xyz.exe' has extra information attached to it that might be lost if you continue copying. The contents of this file will not be affected. Information that might be lost includes:
:KAVICHS:$DATA

Message about 'KAVICHS' on each NTFS file is informational. It means that Kaspersky Anti-Virus service information was written into file's additional data stream. After uninstallation of Kaspersky Anti-Virus this information is not deleted, because it can be used with next installations of Kaspersky Anti-Virus.
