The problem with virus software, is this virus software

You can use any antivirus software. But be sure to upgrade.

You also said that you often use your portable hard drive to copy files on the Internet. Does that mean your computer is indirectly accessible? I don't know much about other software.

Any antivirus software installed on a computer without an internet connection cannot be upgraded without the help of a mobile data drive, so if you install antivirus software, you can deal with some known viruses in the virus database, but you can't do anything about new viruses and virus variants.

Minimize the contact and use of mobile storage such as portable hard drives from computers without Internet access.

Oriental Guardian 2005, the first function to detect and kill unknown viruses without upgrading!

It doesn't matter if you don't upgrade, I don't think you can see those new viruses and Trojans or something, not to mention even fewer that can automatically infect mobile hard drives.

Summary. Dear, it is recommended to disconnect the network and install it directly with the installation package of the application, so that you can prevent the firewall from blocking. May you have a light when it's dark, an umbrella when it's raining, someone to accompany you on the road, and if there are no other problems, I wish you a happy life.

The computer says that the operation could not be completed successfully because the file contains viruses or potentially unwanted software, but my real-time protection against viruses and threats has been turned off.

Dear, it is recommended to disconnect the network and install it directly with the installation package that should be used by pickpockets, so that you can prevent the firewall from blocking the wheel. May you travel this letter with a light in the dark, an umbrella in the rain, someone to accompany you on the road, and if there are no other problems, I wish you a happy life.

Right-clicking the mouse button shows that the operation could not be completed because the file contains viruses or potentially unwanted software.

In case you turn off the network, then turn off all your firewall security systems and try again.

That's it, just a single right mouse click, and this is displayed.

It's not an installation.,It's just click on the desktop.,Right-click the mouse.,Want to refresh the interface.,The result pops up this.,The property interface will be displayed after the fork is crossed.。

Computer viruses.

Problems caused by programs can disrupt computer network systems and microcomputer systems.

1. The harm of computer viruses to network systems.

1) Virus programs infect systems that are operating by "self-replicating", and compete with normal programs for system resources, paralyzing the system.

2) Virus programs can flush out system memory during an attack.

The large amount of data in the computer and its users is lost, resulting in huge losses.

3) Virus programs not only harm the computer system used, but also other computer systems connected to it through the network.

4) Virus programs can cause the failure of the computer-controlled air traffic command system, the loss of control of satellites and missiles, the paralysis of the banking and financial system, and the disorder of automatic production line control.

2. Computer viruses on microcomputers.

Hazards of the system.

1) Destroy the file allocation table or directory area of the disk, so that the information on the user's disk is lost.

2) Delete executable files on soft and hard disks.

or overwrite the file.

3) Write illegal data to the DOS memory parameter area, causing a system crash.

4) Modify or destroy files and data.

5) Affect the normal execution of memory-resident programs.

6) Marking false bad clusters on the disk, thereby destroying the relevant programs or data.

7) Change or rewrite the volume label of the disk.

8) Repeatedly infect copies of executable files, resulting in a reduction in disk storage space and affecting the efficiency of system operation.

9) Perform a specific format on the entire disk and destroy the data of the whole disk.

10) Make the system hang empty, causing the monitor keyboard to be blocked.

The reason why the virus is made is nothing more than two purposes, one is to make money completely, and the other is to steal other people's information to make money by the way, and the harm is information leakage, and in serious cases, it may also cause physical damage to the computer, such as CIH

Hello, there are many possibilities for a mobile app to be judged as a risky app by antivirus software.

1. The application is an unofficial application and has not been officially verified.

3. Virus software, such as fee deductions, advertisements, etc.

If these software in your mobile phone are official software, it may be because of the second situation above, these software will query personal information, please pay attention to protection. (I usually use these software, but mine is officially verified, not virus software).
