Just one more thing.

It's been suggested by experts never to rely on an on-line virus scanner for
protection;
you need to have a full-featured av installed.

cquirke (MVP Windows shell/user) AKA cquirkenews@nospam.mvps.org
hinted in a recent message that:

"Once infected, the malware can and often does resist removal, and is
better-positioned to control the PC than you are to get it back.
In this situation, the more chance the malware has to get control of
the system, the less chance you have of getting it back.

Online scanners are the most unsafe in this situation, because by the
time you've started your infected Windows and connected to the
Internet via this infected code base, and start to look for scanning
sites through infected DNS, you are almost certain to have the malware
perfectly positioned to overrule your attempts to clean it."

So, the way I understand this it is quite okay employing on-line scanners
for a routine check.
But they are unsuitable for removing pests.

A much better, safer and more suitable application is David Lipman's
MULTI_AV tool. The applications therein can be safely used for both routine
checks and malware removal.
---
Download David Lipman's MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go
through your
FireWall to allow it to download the needed AV vendor related files.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in
Normal Mode.
This way all the components can be downloaded from each AV vendor's web
site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot
the PC.

You can choose to go to each menu item and just download the needed files or
you can
download the files and perform a scan in Normal Mode. Once you have
downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe
Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to
run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal
Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more
comprehensive PDF help
file. http://www.ik-cs.com/multi-av.htm

if they can interfere with removal (which the can) what makes you think
they can't interfere with detection? (hint: they can)

online system scanners are next to useless... online file scanners (like
virustotal) can be useful however...

Okay, hint taken! I am glad I wasn't wrong altogether :)

Now, if in future an unwitting participant of this group requires
info/advice concerning on-line system scanners would it not be appropriate
advising him accordingly and offer a more suitable alternative such as
David's MULTI_AV tool?

In the meantime, I've deleted all my shortcuts for on-line system av
scanners.

i dunno... it seems to me that david is pretty good at giving david's
advice already...

however, if you really want to avoid the possibility of installed
malware interfering with the detection/removal process you should be
looking at some procedure that involved not running code from the
suspect machine's drives... i think the question of using multi-av with
bartpe has come up before - i wonder where that got to...

hmmm... didn't realize my argument was so compelling...

Well, I figure that a technical person like you writing and article in
http://www.claymania.com/halting-problem.html would not make rush statements
such as "online system scanners are next to useless...", unless you tell my
otherwise :)
(I do realize that your article does not touch the subject "online-system
scanners).
