(original answer, original author of this answer: history of King Smart)
1. There is a Trojan horse in the computer or a virus is interfering!
try: antivirus software, 36 security guard +36 antivirus dual-engine version, or Kingsoft Guard+Kingsoft Internet Security.
Suggestion: fix "high-risk" and "important" vulnerabilities! Use "Trojan Cloud Kill" and "36 Antivirus",
"Full Scan" and "Custom Scan" to delete viruses and Trojans, and then restart the computer!
after booting, click "quarantine | recovery" to find trojans and viruses and delete them completely!
2. If the first method fails, download a "36 system first aid kit" or "Jinshan system first aid kit"!
first "completely kill", after killing, delete "suspicious self-startup items" and trojans, and then restart the computer!
then click the "isolation | recovery" area to find the "suspicious self-startup item" and Trojan horse, and click "Delete completely"!
click "repair", "select all", and then click "repair"!
3. Use "36 Security Guard", "System Repair" and one-click repair! Again: "clean up the plug-in", scan immediately, clean up immediately: bad comments on the plug-in!
4. The program you downloaded "Player", "Chat Software", "IE Browser", "Driver" or
"Game" is unstable, or the version is too old! It is recommended to uninstall it, download a new one, or upgrade it to
the latest version!
5. Software conflict. You have installed two or more similar softwares (such as two players, two
qq, or multiple browsers, multiple antivirus softwares, multiple online games, etc.)! They are not "compatible" together.
Remove the "extra" one!
6. uninstall method: you can find "powerfully uninstall the software on the computer" in the "start" menu in the lower left corner of the computer, and find the extra one to uninstall! "Strong cleaning" after unloading!
or "36 Security Guard" and "Software Manager", click on "Software Uninstall", and click on
to find "redundant" and "similar" software uninstall! Such as: "player", click on it, leave "storm" and uninstall "fast broadcast"! Such as "download": click to open, leave "Thunder" and unload "Express"! (Don't unload the useful ones until you see them.)
7. If it still doesn't work, download a "read repair tool" on the Internet and try to repair it!
8. If you can't do it again, restart the computer, press "F8" and press enter, enter "Safe Mode", "Advanced Boot Options" and find "Last Correct Configuration". Press it to try and see how it works!
9. No more, start the menu, run, enter cmd, press enter, enter at the command prompt (just copy):
for% 1 in (%windir% \ system32 \ *. dll) do regsvr32.exe/s% 1
Paste, press enter, and restart the computer until the screen scrolling stops!
1. If you really can't, just "restore" the system or "reinstall the system"!
