I don't think I have the software with me since my dad bought this second hand laptop. I haven't reset my PC before and my uncle said that I shouldn't do it without a software or it wouldn't be able to properly download the system and such. Going back to the kaspersky topic, My uncle said that I should probably upgrade my version to premium in order to be more secured. I also did a selective scan to the zip file of the latest version and it detected nothing so I thought it'd be better if I delete the zip file.
