    1. Scan your machine using Kaspersky anti-virus and/or malicious code detection software with most up-to-date signature.

    1. Preventive Measures

    These phishing e-mails and websites are designed to look like the real ones. Fraudulent bank websites for example, are hosted to lure you to give your account information. The most common way is through e-mail and pop up instant messages, where "banks" or "distant relatives" ask for the user's personal information and password.

    Here are some guidelines to avoid falling victim to phishing scams:


    • Remember that legitimate companies will never ask their clients to send over sensitive information online. If you are unsure, you can phone the company to verify if they have sent such an e-mail.
    • Type the actual URL address (if they are safe to visit) yourself instead of clicking onto the link inside the e-mail. Sometimes, the scammers may send you a URL that looks proper but secretly links you to a fake website.
    • Lock your computers and mobile phones in case they fall into bad hands
    • Change your passwords regularly


    • Open any e-mails or follow any URL links from non-verified sources or e-mails.
    • Open attachments from unknown e-mails, as they may contain computer Trojans (a type of malware) that records your keystrokes when you enter your passwords and spies on your computer data without your knowing.
    • Have sensitive information such as ID-card number, credit card details, drivers licenses, or passwords saved in your computer. This makes you particularly vulnerable to Phishing
