Why can t I open my newly installed reading software? 30

You can first remove the "Hide the extension of the type of file" in the "Folder Options" and then change the extension of the antivirus software to "com", so that it can be opened.

This is because your system file association has been modified by a virus, and all executable files (.).exe) can't be opened. Just modify it back and you're good to go.

To modify a file association, you need to use the following two commands:

ftype shows the application that needs to be used to open the file type.

ASSOC shows that the file type corresponds to the open type.

Normally, .exe and. The configuration of the txt file type is as follows:

From the command line, type: ftype txtfile

System return value:

txtfile=c:\windows\system32\ %1

Input: assoctxt (with a space in between).

The system returns: txt=txtfile

The above shows that the txt file type is opened by the virus, it is possible that the configuration path behind the txtfile has been deleted, that is, after the ftype txtfile command is entered, it gets: "The file type cannot be found, or the relevant command is not opened" and the like, then we need to manually configure it, enter:

ftype txtfile=c:\windows\system32\ %1

assoc .txt=txtfile (with spaces in between).

That's when it changed.

If you find the above method troublesome, you can create a tool on the web, such as sreng (i.e. System Repair Engineer), and change its file extension to".com", you can open it, select "System Repair" - "File Association" in it, the software will select the wrong file association by default, you just need to click "Repair" directly.

After the modification is returned, a full antivirus should be carried out.

I think it's poisoned. I've also experienced that I had to reinstall the system at the end! ~

After restarting, press F8 to enter safe mode, if your antivirus software can't be opened, I think you have to reinstall the system.

It's because your computer is hit by a Trojan horse or virus, it will forcibly prohibit you from installing antivirus software, I have also had such a problem, just reinstall the system.

First of all, the computer will be installed Hu Jin Pea Pod, and then use a data cable to connect the computer, after the computer runs the Pea Pod, the software will automatically pair your mobile phone to drive Qing Short and the mobile version of the Pea Pod, and then you can be normal ** software.

Maybe the installation went wrong, you look for Add Remove program in the control panel, uninstall it, and reinstall it.

Or maybe you didn't have all the components installed, and you put all the ones on the disk. The end of the exe (i.e., the application) or the compressed package is copied to a new folder on the desktop, and try again after installation.

Reload, or the next one. Generally on these two issues.

After removing Jiang Min completely, install a Kaba.

Take Kaspersky in Germany and it is the number one in the world.

There is no such perfect software.

All are very large, I have used a lot, none of them are good, Kaspersky is recommended, dichlorvos is also good.

The little red umbrella is enough for free, go to the official website up and down, and it doesn't take up much memory.

No matter what kind of antivirus software you have, you need to protect it. The most important thing in computer security is protection, not poisoning. Norton+360 is recommended

There's no need to pretend. Personally, I think that as long as you sign your name, you can install it, and the compatibility is good. The big deal is that it is maliciously deducted, and try not to save very commercial confidential documents in the mobile phone, and the mobile phone reinstallation system is also * View the original post

It is necessary to install anti-virus software to add some protection.

Plan 1 [New P].

Note [Original]:

1 In safe mode, the effect is even better!

2.All the software to be used below should be installed or upgraded to the latest version to ensure the effectiveness of use.

3.It is not antivirus, and the following methods can be used directly. If it doesn't work, use a high-quality antivirus (e.g. Kaspersky) in safe mode to kill it, and it's best to use 360 Security Guard as well.

Use 360 Security Guard's "Trojan Horse" - Full Scan". Kill and restart. ）

You don't have to use all of the following methods, you can try them one by one. Sometimes, just the first one works.

One. Close the browser, open the new version of 360 Security Guard's "System Repair", according to the situation, select "Home Repair", "System Repair" and "IE Repair" to tick (you can also select all.) At least select "System Repair"), and then click "One-click Repair".

Too lazy to install it, just use the 360 first aid kit directly).

Then use the 360 first aid kit. [Follow the steps: "Start First Aid" first; After scanning, if a Trojan horse appears, click "Isolation"; Then click "Repair" (you can select all of them to Fix Now".

Next, click "Recover Lost DLL Files", add the missing DLL files that the system detected during detection, and then click "Repair Silver Recover Now". Repair Network is a case-by-case decision to fix or not. When you're done, you should restart.

Two. Scan with 360 Security Guard's "Clean Plugins" to clean up malicious plugins. When you're done, you should restart.

Three. Use Windows Cleanup Assistant (from the web**). After scanning (if you sweep things out, check them all and clean them), then use Fault Repair (select all), and then right-click on the desktop to refresh. Works well in safe mode.

You can also consider using the Kingsoft First Aid Kit [After point scanning, if there are items that can be repaired, after selecting all, point repair can be done. 】

Emphasis ---1In the repair, when there is a prompt in Kill Soft or 360, please click Allow. Restart the computer if prompted to restart during operation.

2.When the effect is not good, look at the three points in "Attention". 3.

After that, if the effect is not good, you can also consider system restoration (choose a restore point).

Yes, and preferably in other areas, because the software, especially this kind of large software, system-level installation, will affect the speed of the system, and whether the poisoning is serious or not has nothing to do with the installation location of the antivirus software!
