Run, find the hkey classes root exefile shell open command key, and change the default value to"%1" %*

Restart and change it back again.

Poisoned... It is recommended that you click Tools on My Computer Folder Options View Show All Files and Folders by clicking OK. Take a look at the ** files that have popped up. Delete.. Reboot. It should be fine.

Option one is for you to modify the registry. Click "Start", select "Run", type regedit, click "OK", the registry will appear, and do as he says.

When you open each disk, you first right-click to see if there are a few more things, such as autorun, open in DOS or something. That's poisoning. The next autorun kill will be normal!

I haven't encountered it, but I feel that the first one is also a virus! But I've encountered such a virus, at least it won't open your software!

It should be poisoned, let's kill it.

Restart your computer. Press F8 to enter safe mode. Launch your 360 Antivirus.

If you want to set the default opening method, here I have two methods:

1. Left-click to select the file you need to open, right-click the file, select the opening method, click OK, here you can choose the program to open the file, remember to check the one in the lower left corner, and you don't need to click to open the same file next time!

2. Open the control panel of the computer, click on the program in the lower left corner, on the right side of the **, you can change the default program of the computer, I hope it can help you!
