Type of Behavior Issue

Claude modified files I didn't ask it to modify

What You Asked Claude to Do

Every time I try to build a model around the current Hantavirus news, it blocks me with a breach of safety regulations error. I am not trying to build a virus, I just want to build a model to see the probability of this virus becoming a problem for trading the markets. Can you look into if there are false positives when it comes to the hantavirus or any other virus model building questions?

What Claude Actually Did

I asked claude to help me build a graphical model to where I could monitor and model out the hantavirus outbreak to try to help me in my trading.

Expected Behavior

I anticipated it to plan out and help me build a small web all that let me tweak the figures based on current news cycles.

Instead I get this block:

Can You Reproduce This?

Yes, every time with the same prompt

Steps to Reproduce

Try using this prompt:

the virus I am looking at appears to be transmitted by close contact (bodily fluids most likely for now, possible for the virus to live on surfaces for a time being, average incubation is 1 to 4 weeks, so picking 2 weeks is safe. mortality rate is around 38%. most cases appear to be asymtomatic from day of infection until the end of the incubation period. I am unsure how long the infection period is or how long the patient is infectious after showing symptoms. this is what I have so far
