Can the stress test meant for a quad core i5 chip damage a DUAL core i5-560M cpu??

I took my laptop 4 repair today for addware removal. After 24 hrs of HW testing I was told all four cores of my processor failed the test. But I have an Intel core i5-560M in the machine which is a dual core; not quad core! Could the stress test designed for a quad cord CPU have damaged my machine's CPU??
Is this an easy mistake to make or does the fact that they spent a day running the wrong test (for a quad core chip) mean that this shop is bad news and I should take my machine elsewhere?
Thank you for your advice!

  1. The CPU appears as four threads, due to hyperthreading. This is normal, and running the stress test at four threads is normal.

    Most likely your machine is full of dust and overheated, causing it to shut down.

    I know the dual core would show up as four (same as a quad core shows as 8), but what the guy told me was that all four cores in my machine failed and that this was unusual, So it didn't sound that he was aware of two of them being virtual....does it?
  3. It doesnt sound like he was aware, but it wouldn't have damaged it, if it presents 4 threads then it was the correct test.

    There ARE NOT two virtual cores. There are two cores. Each of them shows up twice. None of the threads are in some way inferior, or less present than others.

    I strongly suspect he didn't want to get into an argument over the difference between a core and a thread. It can be very hard to convince the average person the difference.

    Do you know what program he was running, and what the errors were?
