Question: since I often encounter data loss resulting from virus attack, I want to know whether there is a way to avoid data loss caused by virus attack without installing antivirus software. Answer: in general, if we want to avoid virus attack without installing antivirus software, we need to use system built-in firewall. Now, let me introduce how to use Windows 7 built-in firewall.
Windows 7 built-in firewall is able to prevent computer virus from attacking computer effectively. In addition, operations are simple, too. After opening "Control Panel" of Windows 7 and clicking "Windows Firewall", we can see the following interface:
In this interface, select "Customize Settings" to enter the next interface:
Then, make settings aiming at 2 types of network environment. This first one is "Home or work (private) network location settings", and the other is "Public network location settings". Then, click "OK" button.
If we are unsatisfied with former settings, we can select "Restore defaults" to restore factory settings.
At last, we need to select "Advanced Settings" to make settings aiming at different network environment, like import policy, export policy, and restore default policy. After these operations, Windows Firewall is opened successfully. Though Firewall can prevent the vast majority of viruses from attacking computer, Windows 7 may be attacked by these viruses with mighty infection. In order to reduce data loss to the largest extent, we can spit Windows 7 partition and store important data to 2 different partitions. To split Windows 7 partition, we can select professional partition magic like MiniTool Partition Wizard.
