DON'T INSTALL TWO ANTIVIRUS IN A SINGLE PC,IT LEADS TO HARM.

I HAVE SEEN MANY FELLOW TO INSTALL TWICE ANTIVIRUS,THEY SAID THAT TWO ANTIVIRUS MAY PROTECT OUR PC EVEN BETTER,BUT IT CAN BE MORE EFFECTIVE IN THIS WAY.
THREE KIND OF DISADVANTAGE ARE THERE.
 
1. YOUR PC WILL BE SLOW IN THIS WAY.
 
2.YOUR NET SPEED WILL BE SLOW(UPDATING PROCESS IN ONE TIME)
 
3.IT INCREASE THE TIME FOR RESTART AND SHUT DOWN OF PC,
MANY MORE THINGS THAT ADVERTS THROUGH TWO ANTIVIRUS.
SO BE ALERT DON'T INSTALL TWO ANTIVIRUS.
