  Only download files and software from reputable websites. Avoid clicking on pop-up ads or downloading “free” versions of paid software, as these can be loaded with malware.
• Use Secure Connections:
  Ensure the websites you visit are secure, as indicated by “https” in the URL. This is particularly important when entering sensitive information like credit card details.
• Example:
  A user receives an email claiming to be from their bank, asking them to verify their account information through a provided link. By recognizing the signs of a phishing attempt and avoiding the link, they protect their personal information from being stolen.

Using Strong Passwords

• Complex and Unique Passwords:
  Using strong, unique passwords for all your accounts is one of the simplest yet most effective ways to protect your online security. A strong password includes a mix of letters, numbers, and symbols and doesn’t reuse any part of your other passwords.
• Consider a Password Manager:
  If you have trouble remembering complex passwords, consider using a password manager. These tools securely store your passwords and can generate strong, random passwords for you.
• Example:
  Instead of using “password123” for multiple accounts, use a password manager to create and store a unique password like “Jk!78zLp@qR2” for each account, significantly reducing the risk of being hacked.

  Start by checking if your antivirus software is blocking or restricting the other program. You can often resolve the issue by adding the conflicting software to your antivirus’s exclusion list. Additionally, ensure that both the antivirus and the conflicting software are current, as updates can fix compatibility issues.
• Example:
  You install a new game, but it crashes every time you try to launch it. Checking your antivirus settings, you find it blocks certain game files. Adding the game to the exclusion list allows it to run smoothly without being interfered with by the antivirus.

What to Do If Your Antivirus Misses a Threat

• Immediate Steps:
  If you suspect a virus or malware bypassed your antivirus protection, disconnect from the internet to prevent further damage. Next, run a full system scan with your antivirus software. If the threat is still undetected, consider using a secondary on-demand scanner, like Malwarebytes, to double-check.
• After Removal:
  Once the threat is removed, update your antivirus software to remain current. Review your system’s security settings to prevent future breaches, and consider adjusting your antivirus’s sensitivity or adding additional layers of protection.
• Example:
  Your PC shows signs of infection, including slow performance, pop-up ads, and unusual behavior. Despite running a scan, your antivirus doesn’t find the issue. Running Malwarebytes as a second opinion detects and removes the malware. You then update your primary antivirus and review your security settings to prevent a recurrence.
