I have used AVG and Avast free for years. I have AVG currently installed on my desktop. I have not had any problems. No viruses or malware. AVG is better than Avast when it comes to detection rates and malware removal. However it needs to improve its interface. Avast is better when it comes to interface and tech support. (yes Avast has tech support for free users)
Other than that I love AVG. One of its best features is that it scans resource-wise. (Meaning that if you are using your computer it will decrease its ram usage)
