Install two antivirus together

Can I install on my computer two antivirus programs together?
Or Anti-virus software and Internet security software. Together?

If you have two antivirus programs make sure only one is doing real-time checking, or your computer may get pretty slow as every file is checked twice.

I wouldn't recommend multiple AV on the same computer.

I agree with Doug. If you install two antivirus, your computer become slow.

some antivirus software has functions for internet protection and other situation : some internet security software has functions of antivirus protection.
It's means that in many cases antivirus software & internet securty software can not work together correctly

Not only will your computer become slower, but the softwares will conflict with each other. Best to keep the better of the two.

Yeah, 2 antivirus apps can actually work against each other - each one stopping the other from doing its job, i.e. blocking/killing viruses! However, there are some apps which are compatible with certain other apps (presumably because they each target different types of malware). You just need to do some Google research as to what is compatible with what. I have a separate firewall, antivirus and antispyware running.
