My New Config

Antivirus: Avast IS -Good
Second Opinion Scanner: I recommend Hitman Pro (for scanning) or Emsisoft Emergency Kit
Add-ons: I recommend WOT and Bitdefender TrafficLight.
What is the UAC setting?
CCleaner and Revo Uninstaller -Good
 
Thanks Malware Manic

Second Opinion Scanner: Added Emsisoft Emergency Kit

Add-ons: Added Bitdefender TrafficLight and WOT

UAC set to max setting

Is there anything else I should add?
 
Follow this Guide to Create a System Image in Windows 7, and a Windows Repair disc for emergency.

You can backup your personal data to an external medium (ie. USB or External HDD), be wary of using online backup services.
 
Thanks Earth I already have a External HDD and a Windows Repair disc for emergencies, looks like I'm set :)
 
Nothing really to add to this config.

It is secure enough.

Could I ask how is Avast IS performance for you?
 
Hi Biozfear

Avast IS is very lite on my system I'm not getting any slowdowns at all :)
