Run 2 Anti-Viruses at once is safer?

post #1 of 24
Thread Starter 
Is this true?
My college teacher today said running two anti-viruses at once is better because sometimes the virus can attach itself to the actual anti-virus program itself and obviously it doesn't scan itself, it just scans everything else then you still have the virus.

If you run 2 then they also scan each other.

Is this true? is it recommended when you scan to use 2 different anti-viruses at once?

It is certainly true that some malware specifically block or alter anti-virus apps to hide themselves.

Not sure if running two is the best idea though. A virus can alter more than one anti-virus app. Might as well run 3-4 apps to be safer? Also, I wonder about resource conflicts when both are running.

The safest way to not get a virus is simply don't open or download anything your not sure is safe. I know that norton will detect certain items on macafee and visa versa as virus and delete the core essentials out. I don't recommend it. What I recommend is getting a server side virus scanner. (I believe there are some out there from some major companies) and having it scan your computer.

I agree with duckie, there will be some conflicts between the two.

Best way to prevent virus infections is always keep your programs updated, and think of the internet as a mine field, you go to certain spots you will get hit.

I have seen some pretty bad problems with computers running two anti-viruses.

I also agree with the others. It's known that any 2 anti-viruses will cause you problems/conflicts. Also will actually cause you to be less protected.

really?
I wouldn't have thought that make any sense because after all, all they are doing is scanning all your PC files, sure it will make your PC run slow but i can't imagine them conflicting with each other just when you use them to scan your PC now and then.

Thanks for your input though guys.

I don't even use one. But using two would cover the gaps in weaknesses that the other search's algorithm has.

you should be fine, as long as you make sure they arent two combination programs (e.g. firewall and antivirus and antispam, etc.) because the firewall function will block ALL the functions of the other program and vice versa, and neither of them will work properly.... also, running two combo/passive scan programs will cause a conflict in the DNS settings of your modem/router and in many cases will mess with your internet connection.

EDIT: to clarify, because the active aspect of your firewall/passive scanner automatically detects and compensates for DNS settings, and any programs you open or files you save will also get a lot of trouble.

DO NOT USE TWO AV PROGRAMS... You will in no way be more secure and only cause yourself headaches...
