Antivirus Help, Thanks

I want to download Avast but I heard that more than one antivirus on a computer would lead to the antiviruses conflicting with each other. So would Avast conflict with my Windows Defender? Would it affect my Spybot Search and Destroy?

Any help is appreciated! Thanks !

Yes... disable realtime on one of the anti-virus programs to avoid any possible conflicts.
I'm still not sure about the Comodo suite, whether that has a possibility of conflicting or not.

And yes, you could enable realtime monitoring on SUPERantiSPYWARE.

[quote=Zulucker]Hey there mod! I just wanted to ask if any of these anti programs conflict with each other

Comodo Firewall (real time on)

SUPERAntiSPYWARE (free edition, real time off)

Avast! (free and real time is on)

Malwarebytes (no real time)

Microsoft security essentials (realtime on)
could you also tell me/us if i should turn real time on? (on some programs)

i also have Hijack this and CCleaner but i doubt they conflict with the anti stuff.[/quote]
Microsoft Security Essentials and Avast! could possibly conflict... they're both anti-virus programs with realtime features.

A software firewall like Comodo wouldn't conflict with anything, as long as it's JUST a firewall. I'm not familiar with their product line, but if it has a "real time" option it makes it sound like an "Internet security suite" that combines a software firewall with other functions like anti-virus. If that's the case, then it too could end up conflicting with the other two anti-virus programs if it's realtime feature is turned on.

Malwarebytes and SuperAntiSpyware are both anti-spyware programs and as long as they don't have realtime features (or have them turned on), they should be ok.

What "real time" means is that the program runs "in the background" all the time and monitors your computer continuously.

Normally an anti-virus or anti-spyware program will scan the entire hard drive looking for signs of viruses or spyware when you tell it to scan, or on a scheduled basis (my Microsoft Security Essentials for example scans automatically every day at 2AM).
If anything has gotten into your computer since the last time the program scanned, this should find and remove the malware.

However, during the time between scans your computer is still vulnerable if you download something, until you scan again.
So the "real time" feature will check programs you run every time before the program actually runs. Like when you play Maplestory, when you click on the icon to load the game, the anti-virus realtime component will scan just that one file to check to see if it's been infected since the last time you scanned the full hard drive. Because it's only checking the one file (Maplestory.exe), it doesn't take long and you never even notice it.
If it DOES discover a file you're trying to run is infected, it will stop the program from running (and infecting your computer) and usually either ask you what to do, or will automatically "quarantine" the file by moving it to a "virus vault" area on the hard drive to isolate it.
This protects your computer between scans.

The realtime feature in some anti-virus programs may also scan files as you download them so before you have a chance to run something you download from the Internet, the anti-virus program checks it to see if it's safe.

So yes, it's important to have the realtime feature enabled, but only on ONE scanner program.

The problem is, if two or more programs have realtime features running at the same time, it can causes instability of the system when they all try to check a file at the same time.
Also, if you have more than one anti-virus program and they automatically scan at the same time it can -really- slow the computer down as they all try to access the hard drive at the same time. Even if they don't scan at the same time, just having a bunch of anti-virus programs scanning all the time can slow the hard drive down.

[quote=BobR]Now that you mention it, I misread the OP originally... I was thinking of Microsoft Security Essentials.

@klu180 Sorry- like I said above, I misread your message earlier- Windows Defender is not an anti-virus, it's an "anti-spyware" program like "Spybot".

You can leave Windows Defender and install Avast! at the same time.[/quote]

One question, do can you even uninstall Windows Defender? o.o

OT : I have Avast! and Windows Defender and Malwarebytes, they do not conflict with each other, it's all smooth and works out fine in the end.
I also never use windows defender because Avast! is too good.

You should only have one active anti-virus product on your computer at any one time so they don't conflict with each other.
If you want to use Avast!, you should uninstall Windows Defender first.

Spybot does use "real time" monitoring, but as far as I know it won't conflict with any of the anti-virus programs.
The free version of "Malwarebytes Anti-Malware" also won't conflict.
