How can I take a CEH course when....

I bought my CEH course material but Kaspersky Internet Security warned me about many viruses / trojans found within them

I didn't feel comfortable using them anymore on my laptop since this is my main laptop..

Do you think it's ok to ignore those warnings from Kaspersky or am I harming myself?

What would be a good way for me to take my course without fux0ring up my computer?

I hope that the only way to run the course / practice sessions is not through buying an extra computer which has no sensitive info
