1. Trust no one, not even your own partner
The most important tip seems very simple; don't trust anyone when you use the internet. Contacts can be infected with a virus and can just send you a link or an e-mail. Never open documents with exe., this is a virus that tries to take over your computer.
2. Always use antivirus software
A virus can cause a lot of damage to your computer, so it is highly advisable to install an antivirus programme. Antivirus programmes ensure that everything you do on the Internet is monitored. The programme works in the background, so you have little trouble with it.
3. Make sure you have a good firewall
Besides malicious software, there are also many people who can cause damage to your computer. With a good firewall, you can prevent most 'attacks'. Take the time to set up the firewall properly so that the risk of infection is as low as possible. Most antivirus vendors include firewall functionality with a paid antivirus package.
4. Give updates a chance
It is tempting to keep postponing mandatory updates for programmes, but an update is not made lightly. Criminals are always inventing new ways to infect your computer with malware. An update detects, among other things, new viruses that could not be detected in the old version. So make sure you give the updates a chance to minimise the infection on your computer.
5. Always check that the address is correct before entering your (login) data
When you go to a website and fill in (login) data, check beforehand whether the web address is correct. It is possible that you have typed the address incorrectly and ended up on a decoy site. These sites are set up by criminals and their aim is to get hold of your (login) data.
6. Do not download files from the internet if you are not sure of the source.
All sorts of 'free' products can be downloaded from the internet (such as an antivirus programme), but it is possible that these products have been deliberately infected with a virus or malware. You should therefore always check beforehand whether the source is reliable.
7. Too good to be true is often too good to be true
Advertisements are aimed at attracting attention and the more appealing the message, the more dangerous it may be. Always be alert when a 'great' offer comes along and take a good look at it.
8. Disconnect your internet connection when you are not using your computer
Even when you are not using your computer, but it is connected to the Internet, there is a chance that your computer can become infected. When you are not using your computer, turn off the Internet.
9. Never click on links that look suspicious, even if they seem reliable
A new way of spreading viruses is through e-mail and chat software. You receive a message that seems to come from your contact, but as soon as you click on the link you become infected with this virus and you can become a spreader yourself.
10. Beware of 'phishing' messages
Criminals try to make you think that your bank is sending a mail. This mail says that there is a problem and to solve this you need to log in with your PIN number and bank account number. This is an example of 'phishing', but this applies to every message that asks for passwords and pin codes, companies do not want to know this from their customers.
