Welcome to the forum.
Im planning on using avast scanner to scan my system once in a while..
If you use the internet, it takes 20 minutes to infect a system if you don't have an up-to-date System, AV program and a good Firewall.
Scanning your system once in a while will mean that you can expect to format your hard drive and re-install your operating system quite often.
The choice is yours. ???
