1. What to do if there is no software to download things on the computer

When we encounter this problem, we must first confirm whether the target disk is full. Open My Computer and click on the target disk to see the details. If the target disk is full, nothing can be downloaded.

In addition, if you have anti-virus software or security guards installed on your computer, you can uninstall them first and see if these software affect your downloads. If that doesn't work, uninstall the software and restart it.

We can then open the control panel and double-click to open the INTER option.

Let’s click “Delete” in the “General” panel to delete all history and COOKING and take a look.

We then click on the "Security" panel, click on "Custom Level", as shown in the figure, enable all download options, and click OK.

We then click on the "Advanced" column in the INTER option, find the "Security" column, and uncheck the box in front of "Check the signature of downloaded programs".

Further down, you will find, "Allow software to be run or installed even if the signature is invalid." Hook up. Click OK to save.

If you have tried the previous methods and it still doesn’t work, you can click on the start menu and find Accessories-System Tools-Disk Defragmentation. If the disk fragmentation is too messy, it will affect the ability to save the download program. This method can also be tried before. Mine is for this reason today.

2. When the computer downloads something and installs it, what should I use to open it?

1. Generally, when the system prompts you to open the software, it means that the system does not have the corresponding software installed. , the file with the corresponding suffix cannot be opened.

2. In the computer, generally only .LIK, .EXE, .BAT, .CMD and the like can be directly clicked to run, while files such as .DOC, .XLS, .PPT need to be installed. It can only be opened by OFFICE software. Compressed packages such as .ZIP, .7Z, and .RAR need to install decompressed files such as WINRAR before they can be opened.

3. Find the file according to the suffix name of the downloaded file, then install the corresponding software and click to open it.

3. How to display all software installed on the computer

1. Taking 360 Security Guard as an example, other security software operates on the same principle.

Open 360 Security Guard, find the software manager, and find the software uninstall option. You can automatically detect most of the software installed on your computer and view/uninstall it.

2. Taking XP system as an example, open My Computer, find Add/Remove Programs in the left sidebar and select it. Then the system will automatically detect all installed software and programs, and you can also run the software Uninstall processing.

Note: In special circumstances, such as software previously installed outside the C drive, after the system is reinstalled, the registration information of the software on the C drive will be cleared, so the above two methods may not be able to detect it. This software, so I said above, can detect most software. When encountering this situation, you can only inquire one by one.

4. What to do if the computer automatically installs software as soon as it is turned on

First clean up the system startup items. Some software is automatically installed through the system startup items, so we can disable this part. Startup items, taking 360 Security Guard as an example, open 360 Security Guards, select View and click "Startup Items" under "Optimization Acceleration", find the self-starting software you found, and set it to prohibit startup.

Use 360 ??Traffic Firewall to prevent the rogue software from accessing the network, enter 360 Traffic Firewall, and set the management network speed to prohibit the software from accessing the network.

Check the startup items through system commands, open "Start" and select "Run", enter "msconfig" and select "OK". Search the path in each label in the system configuration utility for C:\ Documents and Settings\ startup item, just disable it.

If the above methods are not clear, you can enter the computer's safe mode to perform an anti-virus scan and uninstall the startup items. To enter the safe mode, keep pressing F8 when booting, a menu will appear, select "Safe Mode" You can enter.

Of course, in the daily process of installing software, we must focus on prevention and combine prevention with treatment. Do not download software from unknown sources, conduct anti-virus scans on downloaded software, and be sure to uncheck the option to install other software for software being installed.
