A friend of mine at work just bought a brand new PC for his not that long ago and he said that he doesnt need any antivirus software on it as its not really necesarry also this goes the same with firewall and other security stuff as well. He told me that he uses PC Cillins free online scan known as House Call say once every 3 weeks and that does it all for him. Like find and remove viruses etc. My question here is does House Call actually remove viruses. I know it will scan for them but not sure about removing them.
