7 ways to protect your computer from malware attacks
1. Backup data
One of the best ways to protect your computer and data from malware (malware) attacks is to make regular data backups, preferably at least 2 backups. Data: an offline backup and an archive on cloud services.
Your backup plan must include a backup of your entire system and offline data to store on an external hard drive (assuming USB, etc.) or on a local network location (such as a storage device). Network-attached Storage (also known as NAS).
This type of backup makes sure you can recover from any attack of malware (malware), hardware failure, and other problems.
Remember that nothing is enough. If possible you should make backups from backups that you have stored externally.
After creating the backup, remember to disconnect the external hard drive and store this hard drive in a safe location or disconnect the network location where you store the backup because if the drive is still online and is accessible from your computer, malware can infect those files.
Although you can use 3rd party tools on Windows 10, Windows 8.1 and Windows 7However, you can use the System Image Backup tool to create a backup of the entire system, including files, settings, applications and operating system settings.
File History is one of the typical tools for creating backups of your files. You can use File History on Windows 10, Windows 8.1 and Windows 7. However, File History may no longer appear on the Windows 10 Fall Creators Update that will be released this fall. If using Windows 10, you refer to how Back up data with File History on Windows 10 here
Also if you don’t have a lot of files, you can create regular backups of documents on a USB drive.
If you are a home user, your files don’t change often, you should at least back up your data once a week. If you’re dealing with files for business purposes, back up at least once or twice a day.
There are many ways to back up online. OneDrive is one of the typical online backup examples, but OneDrive is only considered to protect your data from hardware problems, theft, or natural accidents.
If your device is infected with ransomware or another type of malware, OneDrive can synchronize changes that make files stored in the cloud unusable.
A better solution is to subscribe to a third-party online backup service, such as CrashPlan or IDrive, which allows you to schedule or activate backups on demand to prevent syncing infected or encrypted files. .
The only caveat is that most cloud storage services don’t offer bare-metal recovery. If it’s something you need, you can create a full backup the same way you usually do, then upload the liueje data package to a paid cloud storage service, such as Amazon Drive, Google Drive, ….
2. Update (update) Windows and software
It is important to always install the latest updates for Windows and other software on the system.
Companies like Microsoft and others regularly release updates to fix potential vulnerabilities that can be exploited by hackers.
In the case of the WannaCry attack, many computer systems may have been saved from malware, if companies are constantly concerned about security, they will install a security patch released by Microsoft. before the attack occurred.
