I use SpywareBlaster (SWB) and have done for ages. Because it is so 'quiet' it's hard to tell how effective it is at preventing malware installation. My questions are: 1. Would you guys feel that you had a PC secure from malware infection if you relied on SWB alone? 2. What types of infection might you remain at risk from if you opted for the SWB only security regime? My ulterior motive for asking these questions is that a friend has just had a new hard drive installed following a catastrophic failure. The guy who put in the drive installed SWB and Norton AV (not the full security suite) and has given assurances that SWB is sufficient on it's own to protect from malware infection. I suspect that it would be more prudent to have a realtime scanner such as Windows Defender or Ewido installed as a first line of defence. Any thoughts on this please??
