Then can someone tell me what does mb do if i should use it with av software.I mean i'm happy with kaspersky's protection.It just slows my pc's start up a bit.Will it make difference if i use mb also?

Hi everyone,i'm recently using kaspersky internet security.But i guess it slows down my pc a bit.So i want a light av software with good protect capabilities. I just wonder can mb pro with protection module enabled prevent pc from malicious websites,programs etc?I don't download unknown programs or enter suspicious websites so a decent protection can be enough for me.
