For years me and my family have tried to keep our computers safe from online threats. These days, after removing a virus on my 2005 Dell Notebook with Windows XP, I've been using... Microsoft Security Essentials Windows Firewall Firefox with AdBlock Add-on A 2004 Belkin router that's password protected with built-in firewall turned on No problems since having this setup but the notebook is now old, I haven't used it often. Lately, I hear stories of Windows users who claimed to not have used an AV for years and are still fine. How is that possible? Personally, I wouldn't take the risk. The last time I got a virus, it was from a safe site. I got the Security Tool virus from deviantArt back in 2009.
