Trojans, viruses and other malware.

Think before you open a file or link. Practice safe internet practices.


I wanted to talk to you about the difference between trojans, viruses and other malware.

Viruses: A computer virus is a type of software that normally self replicates and can spread copies of themselves. Many times without the user interaction.

Trojans (trojan horse) : Trojan is another type of malware named after the wooden horse the greeks used to infiltrate Troy. It is a harmful software that looks legitimate. Users are tricked to execute the program in the believes that is something good or something the were looking for.

Ransomeware : Ransomeware is a type of malware that restricts the user from accessing its computer or personal files and demands the user to pay a ransom.

There are other kinds of malware out there as worms, bots, spyware, etc.

Many times, users feel safe to surf the web or opening files or attachments on the emails because their computers have an antivirus installed. However, in the case of trojan horses, if the user click yes or execute a file, that will install the malware and the antivirus won't stop it.

How to prevent it? the best way to prevent from getting a virus or trojan or ransomeware is practicing safe internet surfing and backing up files,

My tips for today:

  1. use an antivirus
  2. choose strong passwords
  3. backup your files (either on a dvd, flashdrive, cloud). My favorite is in the cloud. (one drive, google drive, dropbox, etc)
  4. use email and internet safety. Ignore unsolicited emails. Don't open attachments unless you know the sender and you were expecting it.
  5. Avoid untrustworthy downloads, freeware, etc.
See you soon with more tips.
