Re: 2 AV
You could always use the one you trust most to do scanning of incoming and
outgoing mail and use a separate one to run scheduled scans of your hard
disk (while still doing that with the first one). That way at least the
files on your disk get checked by two different programs while you keep the
overhead to a minimum.
Personally, I have every incoming mail scanned (in effect) three times.
That's because I have the benefit of using my Linux machine as an email
server. So incoming mail gets scanned by SpamAssassin (which, because of
the way it works, also picks up a lot of malware) and AntiVir (updated
daily and which intercepts a lot of messages). The WinXP box picks up its
mail from the Linux machine and runs it through AVG (also updated daily).

As Ashley pride has indicated, tt is contraindicated to have more than one
active anti virus
application running at the same time. The reason being is that the programs
with each other and they will fight for resources and consume needless
*may* be situations where a combo can be used but only if you are experienced
software and know both extremely well enough to make sure that only one AV
be performing "On Access" scanning. Unless certain conditions can be met,
having two anti
virus applications installed and running at the same time should NOT be done.
It is OK to use multiple tools if there is one active AV application running
other "On Demand" scanners. For example TrendMicro Sysclean is an "On Demand"
will not compete with an actively installed and running anti virus application.
scanners are also "On Demand" scanners and are OK.

You have to specifically define what "...just run 1 or the other..." means.
If you have two anto bvirus applications installed (formally installed) then
running in the background and will be competing for resources. "On Access"
scanning is when
a anti virus package will scan a file when it is either being read from or
written to media
such as a hard disk or flash drive. If two AV products are formally installed
aruises as to -- Which one will perform the "On Access" scan ? That's the
Now if you have a AV application installed such as McAfee VirusScan and it has
installed and is the software performing "On Access" scanning then you can use
scanner or a Command Line Scanner to perform "On Demand" scans. An "On Demand"
scan is when
you use an anti virus product to scan media only when YOU the user desire it.
TrendMicro Sysclean utility fits this requirement as it has no "On Access"
capability, does not require a formal installation and only performs "On Demand"
Therefore when you stated "I dont mean run them at the same time, just run 1 or
other..." you have to understand that a formally installed Anti Virus package
has EXE and
DLL files running in the background to protect the system from being infected.
have McAfee VirusScan and Norton Anti Virus installed on the same platform
(assuming one or
the other allows it) because if they were *both* Mcafee and NAV EXE and DLL
files would be
running in the background and that would be problematic. However if you
installed only NAV
and you also have handy the McAfee Command Line Scanner (MCLS) you could have
perform an "On Demand" scan as the MCLS does not need formal installation, does
not run in
the background and will not compete for resources.
You can donload handy Front End utilities to On Denmand scanners at Ian
The direct URL for a retiver is ...
This (Win2k, WinXP and Win2003 Server only) utility will download to slef
files that will install Front Ends to Trend and McAfee On Demand scanners. The
will automatically download the needed from their respective vendors.
This way you can have AVAST, AVG, NAV, NOD32 or other AV application formally
be able to perform On Demand scans with an alternate software to verfy False
make sure your system is clean.
Re: 2 AV
| OK I understand this now. I want 1 formal AV and other on-demand scanners
| which wont muck things up.
Here is a list of online scanners...
Trend Micro - Free online virus Scan
McAfee Security - FreeScan
Panda ActiveScan - Free online scanner
Freedom Online scanner
