What happens if 2 antivirus software in 1 computer?

Hi, I hear my friends say that sometimes two antivirus which are not compatible will crash the computer. It will hard the computer. So, I only install one antivirus.

It will potentially crash your computer. For me, it crashed it within hours of an experiment I did. A friend of mine claims she has 2 programs and everything is running fine... so good for her. I still suggest you choose and keep just 1 anti-virus program.

Dont ever use 2 antivirus softwares in one pc, or your system will be unstable even it can be lead to crash with your valuable data on it. Use one antivirus in your pc, as you have already paid for quickheal antivirus then keep using it and you should unistall AVG free antivirus. Your pc will be significantly slow after afew days if you use to continue in present situation.

There is no problem in having more than 1 anti virus, the only negative thing about it is that it might slow down your computer. That's just it, other than that it will help you keep your computer virus free. Some anti viruses can't detect a specific virus, but nowadays, they try to keep up ASAP. You don't need to uninstall either one.

there is no problem in keeping two antivirus at the same time.. but i think the paid antivirus i.e quickheal will be a better protection for your computer.. and also if you have a lesser amount of ram in your pc then its better that you should remove 1 of dem..

If you have two antivirus programs, they are going to read each other as viruses. Maybe not right away but eventually.

It is better you remove avg as it a free version software.Quick heal paid version is very good.If you keep two antivirus.It will use lot of disk space.Also both the antivirus guards will be open.Making use of lots of processes and memory.Another thing is both the antivirus will conflict each other reating problems.

there is no harm in keeping more than one antivirus program in one PC but there is no need to do that. it will only slow down your pc because each software consumes system's resources

Nothing will happen harmful to the system. But some of the anti virus software will not get installed if already there is a AV software.Their program is like that and also may be their business competition. But it will utilize the additional resources of our system.It is just like some other program. I am having one desktop and 2 laptops , in all these we have installed 2 AV software.Spy ware terminator is in all the systems,in addition to some other software. It may require some exception setting for some AV software when installed in combined with other.If i am asked, I will recommend to install more that one as no software is able to identify all the virus.,and we need to scan with many AV Software.

there is no harm of getting two antivirus ..but however with two antivirus..it would only take more resources

You can install more then one antivirus only if they compitible with each other ... Other wise your system will be unstable... Ofcource extra more load on cpu... but it usefull when one antivirus not catch virus then other will help . As i use avast and zonealarm together... I love them together... Yhere also one website virustotal.com where you can scan your suspected file with 35 most used antivirus including avg,avast,macfee,avira,kaspersky,norton,f-secure etc...
