I've noticed this in the last day or two and found it interesting.
If you create a new text file, then save the file with a double extension, for example "Test.txt.exe" Comodo Internet Security will detect the file straight away as malicious.
Instructions:
Open Notepad > type in any random text you like > Save As
Name the file, for example "Test.txt.exe" (without quotes)
Next to "Save as type" click the dropdown and select "All files"
Next to Encoding select Unicode, and save the file.
Comodo deleted the file automatically.
Seeing as files with double extensions are in most cases malware, it would be interesting to see if other AV's have the same behavior.
Try this out and post your results.
