I have a question for the AVG experts here.  

I often scan documents for various uses.  When I do, AVG takes over and 
insists on reviewing the scanned docs, which takes about all the 
computer's available resources for quite some time.

Is there a way to tell it that things that I scan directly to the 
computer don't have to be gone through?

Thanks for whatever insight you can give me.

You can exclude certain directories from scanning- set the location to
save scanned files to be one that's excluded.

Thanks.  I'll give it a try.

Janet has a similar problem using XP Professional - AVG seems to take up 
*all* the system resources when its active. I don't have any insights 
into this though.

I used to run Stinger on a regular basis across all my files (when I had 
Windows on this machine, which is currently running Ubuntu, but that's 
another story). Stinger was also a preferred application at work, this 
obviously only scanned things on your hard drive but it did it without 
making the PC unusable and in fairly short order as well. Perhaps it 
achieved this partially by only looking at "recent" virus types. I 
wonder if the AVG list of viruses is getting so large it takes an 
appreciable amount of time and resources to search across this large 
database.

At work nowadays they use a commercial McAfee product which also seems 
to take up massive amounts of PC resource when its activated.

You may find minimal improvement as it may not be AVG giving the REAL
problem, it might also be that you are scanning documents at a high 
resolution for a large area, plus other processing of the image
going on as well. So AVG may be trying to scan files not completed
yet or lots of temporary files as well.

Please don't set any system or user general temporary files folders
not to be scanned as this will allow all sorts of things that come
in not to be scanned. 

If your scanner is HP their software is notorious for being bulky
and slow for actual scanning.

I have seen scanned file sizes before saving as JPG or similar
compression of greater than 120MB for one sheet of A4. Even some
'small' scanned files as JPG have to be processed as two or more
very large files before they become the 'small' JPG. This process
can be what appears to slow the scanning.

And on a limited test it seemed to work!

I don't quite understand this.  Are you saying that it's because the 
file is so large or that there are several smaller files that add up to 
one large one?  In any case, after a scan AVG takes over and it takes 
quite some time before I can use the computer again - often it seems 
like 30 to 60 seconds.  Ok, that's not real long, but in context it 
seems like a long time, particulary when it happens over and over 
again.

There is just one file that the scanning software (Paperport by Nuance) 
sends scanned files to, and I unchecked that with respect to the 
Resident Shield feature.  Under versio 7.5 I knew how to specify files 
for the periodic scanning process, but I haven't been able to figure 
out how to do that under version 8.

It's an HP machine, software, as I said, by Nuance (which I don't 
particularly like, but it works).  I always keep Windows Tax Manager 
(yeah, I know, I'd rather not use Windows) open, so it shows the 
problem is AVG and not some other programme.

I usually scan into pdf, but this time was using jpg which are fairly 
large.  I can see why it would take time to scan them.  But since they 
are coming from a non-internet, completely safe source, I thought it 
would safe time if AVG could be told that things coming in through a 
particular port or device would not need to be searched.

I'm running on 2gb of memory at the moment.  When I get a new 
computer at the end of the year I'll increase that to whatever the 
maximum is I can get - currently 4gb for a laptop.  Hopefully that 
will speed things up.

AVG's recent change from version 7.5 to 8 seems to have included a 
big increase in functions the programme performs.  Most of the time 
it's not a problem.  Sometimes when I go to a website it takes a 
short time to clear.  And on google searches it looks at all the 
websites on the page to let you know that they appear to be clean or 
not, and that can take a few seconds.  But scanned documents are in a 
whole other class in terms of time.  And the time is wasted because 
the scanned documents, as far as I can tell, come from me and are 
completely clean.

I stopped using McAfee when it allowed a worm into my computer, a 
worm that ended up requiring  a complete wipe of the hard drive and 
reinstallation of all software.  Only the predecessor to AVG was able 
even to detect that there was something wrong.

Janet's PC is running on 2.5Gb of memory at the moment - it would have 
been 3 but one module was faulty! Didn't seem to affect AVG too much 
though.

We don't have any option over this, it just is there. It could explain 
why the system keeps going down with viruses though! As I've said, if 
they were a commercial ISP they would have been out of business a long 
time ago.

Email is scanned in blocks as it is received, similarly it may be 
scanning the temporary and the final files of the scanning process
as they are being created.

If the scanned image is 50MB plus, I would not be surprised.
There may well be all sorts of delayed actions from the scanning process
(e.g. deleting temporary files; also messing this up (e.g. operating 
system deletes file, part way through the scan, AVG then has to work out 
file has disappeared before moving on.

May well be the temporary files are scanned as well, delaying the 
operating system from dleting the files so more copies of the data file
are actually scanned than the final result.

Several things are different, and I would need to delve into the system.

It shows AVG is having a hard time at that point.

Scanning into PDF or JPG actually requires scanning a raw image file 
first (temporary file) which will then be converted into JPG. The 
delay may well be that AVG is scanning the raw image temporary file
that is taking time. Not scanning the particular scanner folder
should stop that.

The temporary raw image file will be HUGE

	11 inches x 300 dpi   =  3300 pixels per column 
	8 inches  x 300 dpi   =  2400 pixels per line
         Page = 2400 x 3300 =  7920000 pixels

	Bytes in colour = 3 x 7920000 (minimum)
                      = 23,760,000  (3 bytes per pixel)

                      = 22.66 MB minimu plus any overhead details stored

	Worst case the data is stored as 32 bits containing a pixel then 
        the size is 

         4 * 7920000 = 31680000
                     = 30.212MB plus other overhead

      At 600 dpi the figure is 4 x larger 90.64 MB (3 bytes per pixel)

Larger paper also increase the raw image size.

If any form of processing is done in software then there will be created 
at LEAST one file for each stage of the processing (contrast, 
brightness, sharpening etc..) as they rarely hold all the stages in RAM. 
The size and amount of files  mounts up quickly.

Remember viruses were first (and still are) distributed via any media
(scanner is not really a media though), so all files have to be checked
on any medium even CD (when read at least). A file written to the hard 
drive is a file, its source is 99% of the time not relevant, as any 
amount of nasties may interfere even with a filecopy process to add a 
virus. Even to JPG files.

So it's scanning each thing more than once because it shows up in 
more than one location?  That makes sense.

The sizes are between 200kb and 750kb per page, colour at 300 dpi.  
Normally I don't scan more than ten to twenty pages at a time, and 
then usually in black and white, so it hasn't been as much of an 
issue.

Thanks for the information.  Makes a lot of sense.
