Tips to Keep Your Device Safe
- Never download software or programs from unknown sources. This is one of the most popular ways for adware and other malware to infiltrate your computer. Download only from recognized and legal sources. To be secure, avoid torrent downloads and cracked software download sites, as the files will almost always contain viruses.
- One of the most reliable ways to be safe online is to use a firewall. It protects users from potentially hazardous websites by acting as a first line of protection. It keeps intruders out of the user's network and device. In today's world, a firewall will protect a user from the risks that lurk on the huge internet.
- Anti-virus software must be kept up to date. These programs should always be updated on a computer since hundreds of new malware threats are produced every day that aim to infect the machine's weaknesses. Antivirus updates contain the most recent files needed to combat new threats and protect your computer.
- Only visit websites that have a secured connection. A site with an HTTP connection does not encrypt the data it receives and therefore is not considered secure. Entering personal information such as email addresses, phone numbers, and passwords on a website with an HTTP connection is risky since it could be compromised and your information was stolen. Websites with HTTPS connections, on the other hand, are secure since data is encrypted and attackers are unlikely to gain access to information exchanged within the site.
