You must keep your operating system OS , software, and drivers updated. Hackers have been known to frequently take advantage of software vulnerabilities to gain access to your PC. The majority of the time, developers release software updates with security patches.

These security patches fix vulnerabilities that hackers have previously exploited. To keep your software updated at all times, you can download a comprehensive antivirus suite such as Avira that includes a vulnerability scanner.

Most operating systems and applications have an auto-update option, too. Always make sure auto-update is on so your computer can automatically keep all of your system drivers and devices updated. Ensure you always recognize where files you download are coming from. With email, even if a file is on an attachment from an email address you trust, ensure the email has been sent intentionally. Some phishing scams can hijack emails and spread malware through trusted email accounts.

That said, most malware is delivered through legitimate free software. Often, the malware will pretend it has a genuine function, such as speeding up your PC. No matter what, your antivirus can protect you by scanning emails and downloads before they can make changes on your computer. Make sure your wireless network and home WiFi are password-protected before going onto the internet.

You can do this by downloading an antivirus with a firewall. You should also ensure your Internet of Things IoT devices have been secured.

You can tell if your WiFi connection is password-protected by navigating to your network list. All open connections not password-protected will have a triangular warning sign next to them. That being said, hackers can also break into secured devices. This can be on both your home WiFi network or IoT devices such as lighting systems, thermostats, and routers. Files larger than 1 GB may take much longer to download and might not download correctly.

You might not be able to pause the active downloads or resume downloads that have failed. Microsoft Security Essentials provides real-time protection for your home or small business PC that guards against viruses, spyware, and other malicious software.
