Best Free Anti-Virus & Anti-Spyware Solutions
I get asked all the time from friends, family and even clients, “whats the best anti-virus program?”. Before the person asks however, they usually already have a problem. Therefore, this post will serve as a place to refer them when they need to prevent and/or remove pesky viruses, worms, Trojans, spyware, or other malware. I’ll update this post as needed – as I change my recommended software preferences.
If you know of any (preferably ) solutions that should be included on this list, or you disagree with any of my selections, let me know in comments below.
If You Already Suspect a Problem Exists…
If you think you have an infected computer, the first thing you should do is run your current AV or AS program, even if it is not up-to-date. If you do not have anything installed, or if it doesn’t work, then try an online scanner. Always run an online scan prior to installing any of the software below, as many threats can hide from newly installed scanning programs. Note you should also disable Windows System Restore and run your anti-virus program again in “Safe Mode”.

A single real-time anti-virus application is a necessity on any PC that connects to the internet.

Anti-Spyware / Anti-Malware
Unlike most anti-virus applications, the following programs can be run on the same machine, and are not usually run in real-time. I tend to use several of these while cleaning a system.
An easy-to-use, simple, and effective anti-malware application designed to quickly detect, destroy, and prevent malware – such as viruses, worms, Trojans, rootkits, dialers and spyware.

Note an online scanner should not be considered a substitute for a real-time detection virus or malware scanner.
