245961 2004-06-19 02:50:00 Hi,

I've been sleuthing around on this comp ( a friend's, I'm the amateur helper) for malware and I was wondering if the dates under "properties" when checking out a file or .exe can be trusted?

If malware doesn't / can't change the date created/viewed or modified then that would be good indication of something's authenticity, wouldn't it?

TIA :D

You can't trust nuttin'.

If I may follow with another Q. Wouldn't it be possible ( I did COBOL coding myself yonks ago) to infect a comp with a file or .exe or virus or whatever and have no visible trace of it? Just "no display" on everything?

245964 2004-06-19 03:23:00 "You can do anything with software" .

You'd need a thorough knowledge of the OS . :D The simpler the OS the better . Again, DOS come to mind . :D

Adding a file means the directory has been written to, so the directory (which is basically a file itself) will usually have access date/modification date/ creation date . . . entries to keep track of and fix .

An OS like *nix will have accounting/security logs which keep records of who is logged on, when, sometimes what they did . . . naughty people try to grab those and get rid of the evidence . (Of course the crude way of just deleting the log files is a big fat clue that someone has been up to something . :D)

A secure computer is one in a locked room, with no network connection, turned off, and with floppy disk and CD slots glued shut .

Now I know.

I'm not paranoid after all, I can relax now. It's all true! :^O
