Hello, here are some easy-to-do protection tips for your PC 

• Try downloading an external firewall that will block any other applications.
• Revise the administrative access of some programs and make sure third-party apps are not allowed through Windows Firewall.
• Use stronger passwords. Make sure that your passwords contain uppercase, lowercase letters, nubmbers and if possible symbols and spaces.
• Disable AutoPlay. Turning off this feature makes your PC safer agains flash drives or other devices with malware entering phisically via your USB port.
• Always set a newtork you connect to as a Public network. This disables file sharing. You can also disable it manually by typing Advance Sharing Options in your Windows search and turning off file sharing from the option for that.
• Disable any remote service programs. Any software that may grant remote service to your computer in various ways is a potential risk to all the computers using the software in the network. You should switch off Remote Access and look for another solution. One way is to remotely connect online using a cloud browser(Maxton, for example) and a remote desktop service (LogMeIn for example).
• Look for suspicious processes in Windows Task Manager that are by programs that are not running. Remove those programs from the Windows Programs and Features menu.
• Always update your Operating System.
• Make sure you set your mail server to block out all spam and spoof messages. A good tip is to have mail software like Outlook and Mozilla Thunderbird. They have such filters embedded in them as features.
• Make sure to isolate all computers in your network that are infected by viruses, because if the virus is a downloader or a worm it may spread throughout the network.
• Provide relevant education to your employees on external information sharing and security practices.
• Add a site and file scanning extension to your browser. It increases the safety of online browsing significantly.
• Turn off any non-essential services and devices such as Bluetooth, for example.
• Insall an anti-malware software on your computer. Most anti-malware programs feature active proteciton against viruses and they also are good in combination with antivirus software. For maximum protection use both.
