antivirus program

Today I installed a free Virus protection called “avast! Antivirus.” I got this information from yahoo knowledge +. Because my original antivirus program was overdue for a long time, I need to install a new program to protect my computer from those new viruses. At first, I didn’t know how it works, but there were a lot of good comments about the program. I decided to install this one because it has Chinese version. It can make me use this much easier. After installing it, I found that there are many useful functions can protect my computer from virus. Besides, my computer works faster than before. I like it.
