Off-topic Suggestion:
Gawan mo nlng yung mga kapatid mo ng child parental control or ng limited user account. Tapos scan your PC with the free Malwarebytes/Hitman Pro or with any anti-virus every night. It also helps to have a good, password-protected firewall. It can help you prevent unwanted changes, made by your siblings, in your PC configuration.
I personally never use a ©râcked "security" software. Mabuti na yung sigurado. Haha
Mahirap na sa panahon ngayon, and mahirap din mag-check/verify ng source code.
P.S.: Yung friend ko nga pala na gumamit ng ©râcked AV galing India, hindi niya alam na nagdodownload na pala ng mga trojan & viruses yung ©râcked AV niya every night. Kaya ayun, in the end, after niya i-repair yung PC niya, bumili nlng siya ng legit na license.
