What can I do to protect myself from computer viruses and Trojans?
These days, practically everyone's online, downloading and exchanging files, and developers are in such a hurry to get their Web sites up or their files out that checking for a nasty bug is more of a courtesy than a requirement. If you're not careful, your computer can end up with a nasty virus that makes your files act oddly, crashes your computer, pops up bizarre messages, or worst of all, destroys your operating system.

Spam Email
Email
spam,
also known as junk email or unsolicited bulk email (UBE),
is a subset of electronic spam involving
nearly identical messages sent to numerous recipients by email.
Clicking on links in spam email may send users to phishing web sites or sites that are hosting malware. Spam email may also include malware as scripts or
other executable file
attachments. Definitions of spam usually include the aspects that email is
unsolicited and sent in bulk. One subset of UBE is UCE (unsolicited
commercial email)
Email
spam has steadily grown since the early 1990s. Botnets,
networks of virus-infected computers,
are used to send about 80% of spam. Since the expense of the spam is borne
mostly by the recipient, it is effectively postage due advertising
How To Create Strong Passwords That You Can Remember Easily
Creating strong passwords for all
your online accounts is not a thing you should do. It is a thing you must
do. Two months ago, my Google account was hacked into. The hackers changed my
password and blocked my access to the account. Luckily, I discovered this early
and got Google to change my password via my secondary email account.
Last week, the MakeUseOf Google
account was also hacked into and the hacker had the audacity to transfer the
MakeUseOf domain out and blackmail the owner. In case you are still thinking
that your password is strong and safe, maybe it’s time to wake up
What
makes a strong password
It must be at least 8 characters long.
It must not have any common words such as 123, password, your birth date, your login name and any words that can be found in the dictionary.

In my opinion, even if your password
consists of the above, it is still not enough. Your password needs to be
totally unique and different for each and every one of your online accounts.
This is to make sure that in the event that one account is hacked into, your
other accounts will not be affected.
You must be wondering how you are going to remember so many passwords when you have a problem remembering your existing one. Here are some steps that I have used and they are very powerful
