can you run 2 AV software on your PC at once and while connected to the
internet eg nortons, avast

does this cause problems?

Bit pointess to run 2x real time scanners (the overhead is far greater
than the lower risk of getting infected). On the other hand having two
scanners installed isn't a bad idea.

i didnt know if I could trust a free product to work as well as nortons

Well yes you can install two bits of AV software but you will have to
configure them not to interfer with each other.

Avasts 'free' version uses the same sig files as their
corporate/commericial products. It being free is a mute ;point. I don't
rate Symantec very highly, Nortons products were high quality and
Symantec ruined them.

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 will interfere
with each other and they will fight for resources and consume needless resources. There
*may* be situations where a combo can be used but only if you are experienced with the
software and know both extremely well enough to make sure that only one AV application will
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 with multiple
other "On Demand" scanners. For example TrendMicro Sysclean is an "On Demand" scanner that
will not compete with an actively installed and running anti virus application. All online
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 they are
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 the question
aruises as to -- Which one will perform the "On Access" scan ? That's the problem.

Now if you have a AV application installed such as McAfee VirusScan and it has been formally
installed and is the software performing "On Access" scanning then you can use an online
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. The
TrendMicro Sysclean utility fits this requirement as it has no "On Access" scanner
capability, does not require a formal installation and only performs "On Demand" scanning.

Therefore when you stated "I dont mean run them at the same time, just run 1 or the
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. You can't
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 the MCLS
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 Kenfick's web
site --

The direct URL for a retiver is ...
http://www.ik-cs.com/programs/Anti-M...-retriever.exe

This (Win2k, WinXP and Win2003 Server only) utility will download to slef extracting ZIP
files that will install Front Ends to Trend and McAfee On Demand scanners. The utilities
will automatically download the needed from their respective vendors.

This way you can have AVAST, AVG, NAV, NOD32 or other AV application formally installed and
be able to perform On Demand scans with an alternate software to verfy False Positives and
make sure your system is clean.
