application error

I have just purchased and installed avast and am receiving this error message repeatedly: The instruction at 0x703348b referenced memory at 0xfffffff. The memory could not be read.

What do I do? What is the problem?

  • Which avast!..?? (Pro/IS)
  • Which version…??
  • OS…?? (32/64 Bit…? - which SP…?)
  • Other security related software installed…??
  • Which AV did you use before avast!..??
