I used to use avg but since iv been with a new internet supplier for the last 3 years I get a free antivirus called f-secure. I think they do a free version as well but I get the full paid package free and have never had an issue with spyware or viruses on both win7 and win8 give it a go. I get 10 keys as well to use on other computers ;)

AVG is Anti-virus software
Malwarebytes is for malware.
Malwarebytes is really good to, plus you can get it for free.

Avast is alright for free too, im pretty sure you can get a 30 day trial of kaspersky, which is the best anti virus software you can get. It's what i use.

I do not sugggest AVG, i have had 2 computers crash while on there service. I use Kapersky now and have 0 problems!

simple solution just use sandbox on windows and you will be fine. Just know it is not idiot proof if you mess up and dont use it and catch a trojan that is your fault. I havent used a AV of anykind in the past 5 years and I am perfectly fine

Don't use AVG. It's nothing but trouble and does more harm than good. Go with Avira, Avast or MSE. Use Malwarebytes as a Anti-Malware/Spyware program along with the AV.

I'd go with Malwarebytes over AVG any day. AVG is for people in their 40's that don't know what a computer is IMO.

Kaspersky is the best IMO

Wrong.
Sandbox just means you can open a file that you think might be infected and not harm your computer.

Download antivirus software brah, Kaspersky is the best their is for me.

Sandboxie also doesnt protect you from viruses or get rid of them.
