| Good antivirus program?

Ƹ̵̡Ӝ̵̨̄Ʒ asked:

okay, i need a good antivirus program that will ALSO help me to get less hacked of my personal information more often.

to make a long story short, somone used my email and then used that peice of information to get my address (>.>), phone number, then signed up for something i didn’t even sign up for! and they were trying to get me to confirm a credit card thingy, or something along that line, so i told them to cancel everything because it sounded suspicious.

my mom was angry because she thought that since i used the computer so much, it was the reason i got hacked, or jacked…

so basically i want to get a good antivirus program that will keep my computer safe and it was also about time i got a program that got rid of viruses.
i googled a good antivirus program and found this.
