病毒、特洛伊木馬和間諜軟件之間有何分別？
黑客會使用多種不同的技巧，侵犯您的網上私隱，並可能會破壞及盜取您的資料。最常見的三種威脅分別是病毒、特洛伊木馬和間諜軟件。
病毒
Viruses are computer programmes that steal personal information, take over your PC, or pop up unwanted adverts. They can even use your computer to attack other people's computers.
特洛伊木馬程式
A Trojan horse is a type of virus that is a computer programme masquerading as another programme. As the name suggests, the programme looks innocent, but opening it could damage or erase your files.
間諜軟件
Spyware is software that monitors and records your internet behaviour without your knowledge or consent. Some spyware may even redirect your internet session through its own server, allowing criminals to potentially extract your personal credentials such as your username, password and credit card numbers.
如何防範黑客侵擾？
- To avoid Trojans, be very cautious when downloading files. Always make sure it is from a reputable source. Never open an attachment or click embedded links in e-mails, SMS or social media from people you don’t know and trust.
- Keep your software updated. Online criminals quickly find vulnerable areas in operating systems (most commonly Microsoft Windows) and other programmes (Adobe, Java, etc). Software manufacturers release regular updates that fix these security flaws.
- Install firewalls and anti-virus software to counter viruses and spyware. Most computers come with personal firewalls – known as software firewalls – pre-installed. For additional security, you can download an additional stand-alone firewall, known as a hardware firewall. For anti-virus and anti-spyware software, there are many kinds available on the market. Always use a reputable brand and be mindful of fake products.
