Running two Anti-Virus programs at the same time is a pretty bad idea opinion, but others may think differently. I think that the real time scanning they use conflicts with that of other other scanners. This occupies your computers CPU and basically slows it down. In a nutshell - your AV is always snooping in and around your system/memory and if you have two scanners doing it at the same time you'll be losing precious speed. I had a friend who has AVG and Norton running at the same time and he asked why his computer was taking so long to boot, and why everything was running so slowly - i got rid of AVG and all ran well. I agree that there are some AV's that run seamlessly together, but you might have to look around for them and i don't know one
off the top of my head - i'm sure someone might be able to offer two that work well together; you might find that Avast and Symantec work well together but i can't guaruntee it! You might like to test a few running together on your system and see their compatability.

I think that Symantec gets a bit of bad press over small issues, but again this might be my own opinion. I used it for quite a while but i removed it because it's quite a pig on taking the computer memory up - however i thought that scanning it provided was top notch. Remember that Symantec/Norton is still a first choice for many of the security wizards out there. You're choice of course though, and i'm sure that others will add their contributions.

I would have to agree with David. 2-AV program will fight each other and slow your system down or worst. You also have to be careful these days that you don't end up with two AV from a web portal, like Yahoo, Cox, or the other that offer free AV. It is still AV and will have the same negitive results.

If you really wish to do so, however, you could simply dissable the Live-Protection of one of them. You would still have the same basic protection while using the computer but, you would have the option to scan your computer with 2 AV programs, if you do not trust Norton so.

I myself use Norton's live protection, but I also use Avast as a back-up scanner (not for the live protection).

Hopefully this helps.

P.S. See you on VQ2 :thumbsup:

You could have two A-V applications loaded on your hard drive at one time, but only have one of the running at a time. You could turn off the other and use the second to run a scan "on demand." The only problem you might have, if one is turned COMPLETELY off, is that the other might report any malware in the other's quarantine file.
Another option would be to have only one resident on your computer, but to periodically use one of the many on-line scans as a double-check.

Do read the comments carefully; there are ways to disable Symantec's active protection and then have the ability to install an AV you prefer without damaging your system - take a look at the post by jgweed.

While you can't have two resident AV programs running on your computer at the same time you can use web based scanners.

Here are a few web based scanners.

Web based online Antivirus and anti-malware scans: (these can be run regardless of whatever else you are using. You must use Internet Explorer to run these as they require Active X).

Kaspersky Anti-Virus Web Scanner

Panda Activescan

Trend Micro antivirus and malware scan:

Trend Micro antivirus European Edition (supports Mozilla based browsers)

Etrust Anti-virus web scanner

online trojan scans here -

Windows Security Trojanscan
See instructions for it here:

In addition, you should be using anti-malware aps. The following are NOT av aps but antispyware and adware aps:

Anti-malware freeware (You can run as many of these as you wish. Generally there is no conflict between these and you should always run several)

Ad-Aware SE Personal is a free version and it can be downloaded from our Mirror Sites in the Download section at Lavasoft website. However, please note that while the free Ad-Aware SE naturally helps you remove all spyware, it does not provide real-time memory scanning; this capability comes with the paid versions.


Click on Adaware SE Personal in “Products” on the left side of the page
The freeware version is sufficient.

Spybot S&D: http://www.safer-networking.org/en/index.html
Be sure to enable “Teatimer” which gives you realtime protection.

Microsoft Windows Defender (this is a MUST HAVE!)
This also provides realtime protection.

SpywareBlaster: http://www.javacoolsoftware.com/spywareblaster.html

Microsoft Malicious Software Removal Tool (Win XP and Win 2000):

A˛ - Free from http://www.majorgeeks.com/download4281.html . Run it, click Search for Updates, then click Scan.

CW Shredder removes some variants of spyware known as the Coolwebsearch Trojan. The Trojan takes advantage of a flaw in a key component of Windows -- Microsoft's version of the Java Virtual Machine -- to install itself via popups often found on porn and illegal software (a.k.a. "warez") sites. Run CWShredder after installing, and have it look for updates. Then click the "Fix" button, and the program will both scan and fix any problems it finds. If your system does not have this kind of spyware, it will give you the good news.

MBSA is an easy-to-use tool designed for the IT professional that helps small and medium businesses determine their security state in accordance with Microsoft security recommendations and offers specific remediation guidance. Improve your security management process by using MBSA to detect common security misconfigurations and missing security updates on your computer systems.
