My accounts getting hacked.!?

[gope]

You are usuing firefox and it is very easy to hack passwords from it, this may be true with other browsers too, you have been clicking on 'save passwords' and this can be decoded by hackers, if you logout without signingoff your account can be hacked without any password, some sites ask for password or allow you to login using facebook/twitter/google etc account which can be easily accessed by hackers, never click a link from an email as you may reach a hackers site, and your details will be asked by them, use alphanumerical passwords and the password should be of atleast eight or more digits and also easy to remember but difficult to decipher, change passwords regularly, never press unsubscribe any mail from unknown person as you are confirming your email to them resulting in your email being sold to others and you will be flooded by junk mails, as you are using gmail click the junk mail and report as junk/spam by clicking the junk/spam button located at the bottom area of the inbox all further mails will be delivered to that box leaving your inbox with genuine mails. Clean your PC with ccleaner available free from http://www.filehippo.com this cleaner will not erase passwords by default and you have to click on the erase passwords and all your remembered passwords will be deleted giving extra space on your hard drive as it also erases your browsing history junk from the sites visited cookies thus preventing hackers from accessing your data. From some sites you may get virus or malaware (collecting your your surfing data and reporting to fishers) they become active when you reboot damaging your computer, this can be avoided by using ccleaner just click on the cleaner to erase data on shutdown and it will clean all your data before shuting down and there will be no virus/malaware when you start your PC again, never allow computers to shutoff in sleep mode as this does not shutoff completely and becomes an easy target for hackers.
