Hit the Toolkit button at the top of this page and you will find some great additions to our weapons for combating malware: Microsoft Security Essentials, Comboxfix, and SUPERAntispyware. The best news is that they are free or have good freemium services, i.e. they can work for free but offer some additional services etc. if you pay a subscription. A good example is our favorite Malware Bytes. The free version does a great job hunting down viruses and other malware but it is not active all the time, unless you pay a yearly subscription of $24.95; then it actively hunts for, stops and/or destroys the malware before it has a chance to infect your machine.
