There should never be short of victims

It seems that the online criminals could succeed by getting personal information or doing harm to individuals because we have weakness.

The famous Nigeria Scam is based on our greediness. The spyware is based on our sexual desire. Check the two cases:

Victoria's secret spyware attack steals hearts, usernames and passwords

"My best photo ever!" Trojan horse spammed out via email

I am sure that victims must be male instead of female for these cases.

It depends on our experience to judge whether such email message could fool us. During the first few years online, one might find these interesting and never worry to click the link. But, with years of experience including bad cases, one should have the knowledge to question why receiving such email.

Do not risk yourself because you have firewall etc. Online criminals are always ahead of any protection methods.
