I once heard a catchy little phrase, "Opinions are like ***holes, everyone has one and they all stink." Much the same can be said about anti-virus programs. I run one actively, but scan with others occasionally just to make sure. They don't all need to be running concurrently (that's not a good idea) but nothing says you can't fire one up to scan a file or group of files on the fly. I've encountered times when a few AV apps didn't catch a thing, yet a scan by another found multiple instances of infection. Doesn't mean that those first few didn't work, it just means that you shouldn't put all your eggs in one basket and depend on a single provider.

Remember, good security and good sense are your best weapons.

AV plus AntiSpy/Adware

by Raven2 In reply to how many antivirus can we ...

Multiple AV running / scanning at bootup is a very bad idea. Having a second AV program to scan on demand has its merits. Don't forget to see if your AV will also protect against Spy/Adware threats. Some do some don't. The same for IM. Close all the doors (ports) you are not using and watch the ones that you have open.

If you are dealing with home desktops, watchout for teenagers, what one does not know someone in their group of friends does. The most fouled up machines I have seen are ones where teenagers have downloaded virus and adware infested junk programs.

More than one

by Jack-M In reply to how many antivirus can we ...

I use Norton, Spybot and MS anti spyware in conjunction with each other. Running WinXP for almost a year I've had no problems, conflicts or viruses. It takes a few minutes but so far it's kept me trouble free and I use my computer on the web at least 30 hours a week in a professional capacity. Good luck.

Not recommended

The reason behind this is that one, it will take a huge amount of system CPU, network bandwidth, etc. to run them. But the main reason is conflicts. You can install two different ones, but your system may not respond properly or may respond but you'll get more system problems.

I don't know exactly why, but I believe it is the code that they write the antivirus software with.

If you want a really excellent antirus software, go with MicroTrends PC-Cillin software.

PC World has rated it as the best in 2005.

by singhsantosh87 In reply to how many antivirus can we ...

hello roger here ....and i would like to tell you that the answer is NO......i work for dell technical support and i specialize in spyware and virus tech support....the worst that u can do to ur system is installing more than one antivirus with FIREWALL...please underline the words....its not the antiviruses that are cause for the problem.but its the firewall that can disable ur internet connection and many other applications...and by far the best that we can recommend is grisoft avg antivirus and webroot spysweeper ...where the former is a antivirus and the latter is a antispyware...trial versions for both of them can be downloaded from

Multiple AV's can attack each other

by jdclyde In reply to how many antivirus can we ...

so you have to be careful.

They see the virus definitions from the other AV and they do not play nicely.

I wouldn't even consider having more than one loaded at a time.

often, not always

by apotheon In reply to Multiple AV's can attack ...

Poorly designed AV software does that sort of thing all the time. AV software from Symantec, Sophos, and McAfee are notorious for that behavior. Something designed to avoid being a problem, like ClamWin and AVG, however, plays well with others (as long as those others aren't from a company like Symantec). That's why I have no hesitations about recommending both AVG and ClamWin on the same system.

It's likely that large corporations whose AV software conflicts with other AV software do it on purpose, in an attempt to keep customers exclusive to their software. Of course, all they're really doing is losing customers who prefer the other company's AV software -- unless their software just sucks so badly in comparison to something else that they know they'd lose customers. Come to think of it, that's probably exactly why they do it.
