like say you have windows defender and avast?
or Avast and an expired norton antivirus?
Answer:
It is okay if they’re two compatible programs, but I don’t advocate having more than one. Obviously, people might think having more will be better, but it is the opposite. Multiple programs might cause conflicts that result in system errors, slowdown, and much more.
Just as a note, Windows Defender is NOT an antivirus, it is an antispyware program, meaning it is safe to use with Avast. It is good to have different programs, but just not two antiviruses.
Answer:
Suppose a girl (virus) has two lovers (antivirus) waiting for her at same place side by side. Definitely there will be conflict. If she goes with one boy the other will disturb and vice versa. So the same situation here. Both antivirus will check your system thoroughly for viruses. If one antivirus moves an infection to quarantine and makes your computer safe, the other will warn you that there is virus. For antivirus every Folder of your computer is suspicious except its quarantine folder. So the quarantine folder of other antivirus is a suspicious one to this antivirus. In this way they conflict.
Hard to understand…. just make sure only one antivirus is there and boths of them are active (not outdated)
Answer:
A expired Norton won’t get any updates so it will not be effective against new virus. The Norton will use up a lot of RAM and slow down your Personal computer.
According to an article by the Washington Post,
Norton Antivirus had one of the worst average response times
for providing virus definition updates based on the worst virus outbreaks,
lagging behind each major competitor, including NOD32, Kaspersky,
Swift Heal, F-Secure, Sophos, Avira, Trend Micro, F-Prot, Panda, Protector Plus, AVG, avast!, ClamWin, and McAfee.
See wikipedia
Symantec/Norton Live update are responsible for BSOD ( Blue Screen Of Death )
for millions of PC in China

I would recommend that you get Avast Home Edition version 4.8.
It now protects against spyware, rootkits, and other forms of nonvirus malicious software.
Ideal of all, it's free for personal use.
Answer:
No, it is actually superior, because one might not pick up a virus where as the other will. The other day I got a virus. Only had one virus protection (McAfee) and it couldn't detect it. I installed AVG Free and it picked it up. Yesterday I got a virus AVG couldn't pick up and McAfee could. Superior to be safe than sorry.
—-EDIT—-
The above two answers are correct, the don’t get along with each other, but you can still have two, put one on active protect (constantly scanning) and the other off. Use one to scan at a time, when it's done, turn it off, then use the other to scan. Contact me for more info.
Answer:
They usually don't cooperate well with each other because they're both accessing similar portions of the system. Sometimes they can conflict and either cause problems with how they work or possibly even think the other is an infection.
Answer:
competition starts between them. your personal gets overloaded as both work on same files and folders. that is why some people's computers shut down while using 2 anti virus
Answer:
They intertwin and find each other as viruses (Some) and makes a lot of issues thus making you unprotected worse
Answer:
They “”MAY”" conflict
