These are a few of the things I use to keep myself safe when online.
Never use your name as an ID on a forum or chat site.
Never put your real name or address into your email address book.
Never use your primary ISP email address to sign up to web sites, keep it for communication with your ISP only.
Most ISPs allow you to create additional email addresses that you can change as you please or you can use hotmail, yahoo or Gmail or better still register your own domain name and get a hosting package, that means you own the name and can change ISPs without ever worring about loosing your email addresses ever.
Depending on hosting packages you can have unlimited accounts and change them as you please.
When an address starts to get spam you simply create a new email address and delete the old one.
I use an excel spread sheet to record all this information so I can quickly find web site address, user names, passwords and email addresses used, in excel this can be quickly sorted by the columbs as you please.
Never use the same password on more than one site, try to use a different user names on different websites, this will stop people doing searches on you where you may have posted some personal info allowing a stalker to get a more complete profile on you.
Passwords should be a minimum of 8 characters and contain both letters and numbers.
Also be very concerned with friends that bulk forward jokes to many people where every ones email is displayed, it is a huge problem because sooner or latter some you don’t want to have your email address will end up with it, it maybe a person you have had prir problems with or even find your self on a spammers mailing list. BBC should be used to hide all email addresses, if the senders wont or cant ask them nicely to stop sending them to you.
Things like eBay and paypal I use different email addresses, I have had phishing emails sent to my ebay email pretending to be from paypal, as I use a different email I know straight away it’s a fake.
Never login into any secure sites like eBay, paypal or internet banking from a link within an email, always type it manually, or from your links/favorites or search from google, but never a link.
It’s of utmost importance to have Antivirus software that is up to date.
Also having Anti spy ware software is important, as AV programs do not detect a lot of spyware.
