Is the phrase "malicious illess" possible?

I'm asking because I had two options to choose in "____- illness which deprived someone of sight...." and I had

[1] severe

[2] malicious

Is [2] possible?

Dear Maverick88,

It is possible to say «a malicious illness». It is however an example of personification. It is therefore fanciful.

There is a phrase «malignant tumour». That is normal. Emotion: smile

Kind regards, Emotion: smile

Thank you, Goldmund, you made it clear.
