    • Mostly adware is able to uninstall, or delete, or by close the webpage you are visiting, but some of them actually will infected to your system and not able to be even turn off; fortunately they will not harm to your file and hardware
    • While infected by malware, you system may halt, crash, files may deleted, or automatically restart, and sending infectious email/files by itself.

  • Emergency stop the suspicious infection:
    1. If you are not familiar with PC, first step to prevent the situation is unplug the network connection, and switch the device off, then switch off your server to prevent virus get spread
    2. Call professional technician to come in and check, don’t take the chance that you may be fine, as the cost will be very high if you are really infected compare to pay just one hour service charge.
    3. If you have computer knowledge, you can try following steps to help you save some data after called technicians:
      1. unplug network cable and switch wifi off to make sure not spreading the virus
      2. Close all applications, and software
  • Open task manager, and kill all those non-system process
  1. Turn on your anti-virus, if you find the process you just killed went on itself, mostly those process will take a lot of system resources and you shall easily find them by CPU and network usage. If you are not able to turn on antivirus, that means 100% you are infected, turn off your device right away.
  2. archive your data with compression software and make it as .7z or other format and get it password protected–this is not 100% will work but may give you more chance to save the data
