Hello everyone, I am setting up the security on my home pc, and have a few questions: Currently using Avast Free, BOClean, Ad Muncher and Windows XP with SP2. 1. I was thinking about changing the virus scanner to Nod32, are their any known problems running with BOClean, Ad Muncher, etc? 2. Do you have to buy Nod32 from the local site? It sends me to http://www.nod32.com.au/nod32/purchase/purchase.htm but can I buy it from the usa site regardless of me been located in Australia. I ask because the USA site is 20$ cheaper then the Australian site and thats after converting the currency. 3. Any other software recommended to use? (must not slow pc performance down to much) Thanks for any help.
