At work I have a whole team to worry about pc security but with my home pc, I am on my own. When I read about Avast! Home as a great FREE choice in Consumer Reports a few months ago, I thought "Avast ??, I've NEVER heard of them!" Quite honestly I was reluctant to try anything than the ones commonly seen already loaded on new pc's, electronic stores, etc such as McAfee, Norton, etc. BUT, I have been very happy with Avast and what I think is really remarkable about this program and the company is this forum! There are so many generous and knowledgeable people here - both users and folks from Avast. I have had questions about Avast late at night, post a question, and I have often received a response in minutes! I really appreciate this and don't think you would find this level of support and generosity from the other "big" AV companies.
