Malware is malicious software that gives a cybercriminal unauthorized access to your computer and puts you at risk for identity theft and fraud. Signs your device might be infected include software or browsers that are very slow to open or don’t open at all, and pop-up ads that warn of potential malware or won’t close. Sometimes, malware destroys all the files on your computer.

You might be able to combat malware with an antivirus program, but that’s not always possible because new malware is created all the time. You might need to take your computer to a trusted expert or have to reinstall your operating system and programs. You might even become a victim of ransomware, where the cybercriminal sends you an email demanding you pay a ransom to get access to your files again.

A malware attack is inconvenient, stressful and can cost a lot of money, too. If you could travel back in time, you would want to do everything you can to avoid it. Here are some tips to prevent the damaging impacts of malware:

• Don’t open unsolicited email from people who don’t know, click on suspicious links or download files you’re unsure about
• Install operating system, browser, software and security updates
• Avoiding visiting websites you’re not familiar with
• Install and regularly run an antivirus program
• Be aware of tech-support phone scams where they ask for access to your computer
• Regularly back up your files to an external hard drive or cloud service

Taking steps now to prevent a computer malware attack protects your information and will save you a lot of time, money and stress.
