Computer Viruses

One of the most serious threats consists of viruses and other harmful programs. A computer virus is a computer program that replicates itself into other computer programs and can cause damage to a computer’s software, hardware or data. Virus on a computer can typically performs some type of harmful action, such as corrupting data or obtaining sensitive information.

The best way to deal with the threat of a computer virus is to use antivirus software.


Spyware is a program installed on your computer that sends information about you and how you use your computer to a third party, typically without you being aware this is happening. Spyware often enters your system when you install some type of free software from an untrusted source.

To counter spyware, you need to use a dedicated spyware management tool. Some antivirus software is bundled with spyware management tools, but they are separate functions.

Phishing Scams

Phishing is an email scam that is disguised as an official communication from a legitimate website. The message tricks people into providing sensitive information, such as their login details. A typical scam consists of a message that describes some issue with your account and requires you to log in to your account to confirm something.

Never log in to your account from a link sent to you in an email.


Spam is a electronic junk mail. Spammers collect email addresses using automated spiders that crawl across Web pages.

Antispam software has been developed to filter out the spam before it gets to your inbox.

Email Attachments

One of the most common ways for viruses, spyware and other harmful programs to spread is through email attachments. When you open the attachment, a program gets installed on your computer, and you may not even notice that anything has happened.

You should scan any attachments for viruses before downloading and not open any attachments whose content you can’t confirm.

Internet Browsing

Simply browsing the Internet presents its own security issues. Certain Web pages automatically launch a file download, and these files may contain harmful programs.

To prevent this information from being stored, you can change your browser settings to private browsing.
