Does AntiVirus Slows Down Pc Speed?....

Yes! Antivirus software can slow your computer depending on how much memory you have in your computer. If you have enough SD-RAM, then probably you might not encounter this problem, regardless if you have so many applications that run at the same time with the antivirus. There are also some antivirus that really eat a lot of memory like Norton antivirus. It is a hog resources, so it should not be used with a lower SD-RAM. I suggest that you download some antivirus that does not use a lot of memory and one of the example is Avira AntiVir Personal Classic Edition. This can be downloaded at www.free-av.com Hope this would help. Have a nice day and God speed!

that depends on the antivirus, for example nod 32 is almost not eating any memory
