Scanning downloaded files
« on: June 05, 2006, 08:10:40 PM »
Just wondering what other ppl are doing in regards to scanning of files that are introduced to your computer by way of files downloaded AND before they are opened...such as files that come thru email, IM, P2P, or CD/DVD ROMS put in your disk drive?

I tend to NOT scan files from "trusted sources," but since the notion of "trusted sources" seems to be relative, seeing what are others are doing might help me figure out how cautious to be.

In other words, what program(s) do you scan with, before you open/install a new file?

Anti-virus?  Anti-spyware?  Anti-trojan?  All of the above?

What files, if any, do you choose not to scan before opening/installing?

Hmmmm Sorry I trust no one when it come to my PC  (As these things are expensive) 
Some  may think it a bit over kill but even if a friend was to scan then send to me I will still scan on downloading it
as files can be intercepted and corrupted on route and while alot of friends find they are having to deal with viruses/Trojans & spy/Malware on a what seems weekly bases I have not.

I don't understand what you're asking, ripley.
Do you mean scanning manually, in addition to the automatic features of AV/AS (anti-virus/anti-spyware) software?
I mean, everything that comes into my system from the internet, including email, gets looked at by my AV, and certain of my AS programs, automatically.  I don't think this process is technically a "scan" though.  Are you saying downloads should be manually scanned by AV/AS, in addition to the protection afforded by their automatic features?

Hey Brynn  :)

Yup, that is what I was wondering...manually scanning an individual file even after whatever "automatic" protection is in place. 

It seems some have been more cautious than I have been.  But when you think about it, how long does it take to right click a file and do a scan of that one file only?  A second or 3?

And then scannning CD & DVD ROMS...well that is something I haven't done before.  Hummm.

ripley,
I scan every thing that is either downloaded from the NET as well as CD/DVD/memory sticks/floppy's and so on.

Hi again,
Sorry for taking so long to reply again.
Wow!  No, I don't scan anything above and beyond the automatic features of my security programs.  But neither am I blissfully innocent  :tease:, or ignorant of the risk.  I do hear that "trusted source" warning (in my head) before I DL anything.  To be honest, it's never occurred to me that installing something could do more damage (potentially) than simply downloading.  I mean, clearly it could, but I've had the impression that the danger is in the download...

So, when one DL's a new program, or whatever, then is the file where one has directed the download, somehow immune, or any less vulnerable than other files?  Or is a download, by definition, somehow safe, until it's installed?  Because if that's the case, I certainly will make it a habit to scan b4 installing!  It's just been my understanding that downloading is a relatively risky process, and that to be as safe as possible, one should request the program on disc, from either its maker or distributer, and then scan the disc b4 installing.

Well, I don't do nearly as much DL'ing as many, if not most people online, which probably goes in my favor.  But I really have been very lazy, choosing to quickly download, compared to waiting for a disc in the mail.  However, if downloaded files are so safe, I will gladly give up my guilt, and BE SURE to scan before installing, from now on.

But are DL'd files really so safe?

I recommend that you trust no one and scan every file no mater how it gets on your PC
So even if you get a CD/DVD to put your Programs/files to your PC still scan them for not only viruses but Spy/Malware too.
As unfortunetally not every one is as carefull as of some of us and think nothing of it just poping that Disk in there PC then wondering why there PC sudenly starts to play up.

It only take a few seconds to scan but it can take a few hours some times longer to remove some of the nasties that are around
