The first thing you should do is install and deploy antivirus software on all your devices. Regularly prioritize and protect the devices you log on to the internet- your phones, tablets and computers. Antiviruses are cheap protocols that protect your devices against malicious programs. Malicious programs are viruses or worms that can extract or infect your information through your devices to damage your data. There are Free versions of antivirus you can install on your device. Those free versions will not give you complete protection like the paid versions.
