Computers of any kind are vulnerable to viruses, hackers, and malicious software. Users seem to think that if they have security software in place there’s nothing to worry about. The truth is, there are plenty of threats that can make it past even the most powerful antivirus, antimalware, and firewalls. Although security software does help protect against malicious software, it’s important to be diligent and always work towards keeping the network safe.
Preventing virus infections isn’t easy. Users will need to learn good habits when it comes to staying safe. Backups are vital to network security. Many viruses hide in temporary files and activate when the time is right. By wiping the system regularly, these infections can be avoided. When the temporary files are deleted, users can be alerted with a message such as restore your data. Wiping the temporary files from terminals should become a habit. The only way to prevent infections is to remove the files that cause them.
Scanning for viruses is something that should happen on a daily basis. These scans should be avoided during peak hours. Instead, they should be done when users are least likely such as after hours. System administrators can schedule scans with system tasks or built-in tools. Using a variety of software usually yields the best results. External scans can help detect viruses and malicious software that may have been missed by security software that could have been compromised. Enterprise-class tools can be much more effective, so business owners should talk to their service provider. Home users can look online for external virus tools.
When a virus is detected, the first thing to do is isolate the infected computer. Physical network connections should be disengaged right away. Wireless adapters should be stopped to prevent automatic syncing of files and folders. Using the software on the computer most likely won’t yield any results since the virus wasn’t detected in the first place. The best thing to do is scan with a live boot of Linux. Outside scans will be able to scan system files since they won’t be in use. Security service providers should be able to provide the necessary tools for these kinds of scans.
