1. What is a computer virus?
Computer viruses are the most popular of malicious software, which is developed with the aim of compromising a computer system. The following list includes the main types of malicious software:
- Virus: small program designed to self-replicate on other computers, like a biological virus that spreads from one person to another. It may hinder the proper operation of the infected computer.
- Worm: uses a computer's resources to replicate and spread to other computers over the Internet.
- Trojan horse: a seemingly legitimate program that executes harmful actions without a user's authorization. E.g.: a back door creates an entrance to a computer system from a distance.
- Spyware: gathers personal information about a user without authorization and sends it to a third party.
Malicious software first appeared at the same time as computers so it is not a new problem. However, the objectives of the perpetrators have changed.
2. What is Desjardins doing to counter this problem?
Desjardins makes sure that its computer systems are highly secure at all times. However, it is your responsibility to be vigilant when using your PC to make transactions on AccèsD.
3. What are the motives behind this kind of crime?
A few years ago, hackers sought recognition and fame. Today, these criminals usually try to use malicious software to steal money from their victims.
Viruses and worms are usually used to:
- Take control of your computer with the aim of using it for fraud without your knowledge. This is particularly true with the development of high-speed Internet access tools like cable modems and ADSL.
- Install spyware to gather your personal information without your knowledge when you surf the Internet. A hacker could obtain your password to access your savings accounts, or your credit card number when you make online purchases.
Test the security of your computer and your knowledge:
- by using Microsoft to check your computer
- by taking a quiz to evaluate your Web knowledge and behaviour.
4. What should I do if I believe my computer may be infected by a computer virus?
The spread of computer viruses on the Internet is a very real phenomenon. This is why it is critical that you install security software on your computer that includes automatic updates and antivirus, antispyware, and antispam software as well as a firewall, Note that these do not, however, protect your computer from new viruses. This is why you must beware if anything appears abnormal on your Internet browser.
For example, one sign that your computer may have been infected is if you are asked to provide unusual information such as your date of birth or social insurance number as you log on to AccèsD, and this despite the fact that:
- the address in the address bar is correct (www.desjardins.com or accesd.desjardins.com);
- the padlock at the bottom the page is closed;
- and the address in the address bar starts with https://.
What to do if you suspect your PC is infected
- Install or update your antivirus program and launch a full system scan.
- Do not use your PC to do your online banking until the problem has been resolved.
- If you have given out personal information or believe your password may be compromised, contact an AccèsD service agent to change your AccèsD password.
- If the problem persists after a system scan by your antivirus program, contact your Internet service provider or the computer support department of the store where you purchased the computer.
- You can also use free scans generally offered by most antivirus software suppliers.
Some antivirus programs detect viruses faster than others, or detect viruses that others do not. Each virus has its own signature, and some programs are more effective in removing them from your system.
For informational purposes, here is a list of online scanners provided by Wikipedia.
Also for informational purposes, here is a list of antivirus software vendors1 provided by Microsoft.

How can I protect my PC from computer viruses?
Viruses
In order for your computer to be infected by a virus, you must have downloaded the file which contains it.
To avoid downloading an infected file:
- Do not open attachments received from strangers.
- Install an up-to-date antivirus program that is automatically updated.
Worms
Worms travel without any help from users and lodge themselves in your computer's random access memory (RAM). Worms replicate and spread from computer to computer in the same network or to computers via e-mail. Worms usually send out copies of itself to all the addresses in the infected computer's e-mail address book.
To keep your computer from being infected by a worm:
- Install an antivirus program and a firewall that are automatically updated.
Trojan horses
Trojan horses at first glance appear to be legitimate programs but do annoying or malicious damage to your computer. To be infected with a Trojan horse, the program must have been installed by the user. Beware of files that have two extensions, (e.g., photo-album.jpg.exe), which lead you to believe it includes photos but is actually an executable program (.exe).
To keep your computer from being infected by a Trojan horse:
- Do not open (click on a hyperlink) or run (double click on a file) you receive from strangers either by e-mail or in chat rooms.
- Beware of files with the following extensions: .exe, .bat, .com, .vbs, .pif. If a file looks suspicious, do not double click on it. If a suspicious file comes from someone you know, contact them to find out if it was truly sent by them.
- Install an antivirus program and a firewall that are automatically updated.
- Configure your operating system not to open or run files automatically.
