Let me add few more tips to this thread:://be more secure//::
1) Must have latest patches/updates of antivirus, antispyware, firewall, OS, and other application installed like office suit and others.
2) Use strong password
make combination of A-Z, A-z, 0-9, and special character like @,_ for your password.
Atleast 8 character long.........
avoid your name, date of birth, username, place, company name.
3) Don't enable the Save Password Option.
4) Lock your computer when you leave your desk.
If you're going to be away from your desk for a while, make sure your computer is locked.
To lock your computer:
## On your keyboard, press CTRL+ALT+DELETE at the same time.
## Click Lock this computer (Lock Computer if you're running Windows XP).
## To unlock your computer, press CTRL + ALT + DELETE and enter your password
5) Use password protection on your screensaver.
