Ist mywot.com sicher?

It's soo addictive to check all the sites i go onto x) Though until now non of them have been malicious... Maybe thats why i'd never tried to have a virus on my computer xD! Or atleast i haven't in my family... My mother once was brilliantly good at installing some kind of ware... Three games that kept reinstalling themselves xD! Poor mother... She doesn't know a thing about computer... Well thats a long time ago now, and now i will use this thing to protect myself. Though i have seen some wrongly rated sites... Please fix! x)
