Adware (advertisement programs), is a malicious code that misuses BHO (Browser Helper Objects) to change the start page or trigger pop-up advertisement windows. To prevent this you should not use “Enable
third-party browser extensions.option on the setting panel.

How to opt out “Enable third-party browser extensions”

1. Run Internet Explorer.
2. Select Tools -> Internet Options.
3. Select the “Advanced“ tab.
4. Uncheck the checkbox not to use “Enable third-party browser
   extensions (requires restart)” and click “Apply.”

A system that has a weak Windows login password or has not installed the security patches will be needlessly exposed to malicious codes or
hacking attacks. Not only that, but even if the malicious codes are
deleted using a vaccine loaded with the latest engine, the malicious
codes can attack system vulnerabilities again to re-infect and damage
the system. Therefore, in order not to be infected with malicious codes
spreading through vulnerabilities in the system, please make sure that
the latest security patches are applied, and that the password for the
Windows login account cannot easily be discovered.

1. Password Settings for the Windows Login Account
   (Windows XP)

   1. Select Windows [Start] > [Control Panel] > [User Account]
   2. Select the account used.
   3. Select [Change My Password] and replace the existing password
      by a new one which cannot be guessed easily. Please note that the
      new password should be a ombination of letters, numbers and
      special characters so that your system cannot be easily infected
      with malicious codes, hich can spread if the password is vulnerable.

2. Apply Security Patches using Windows Update

   1. elect Windows [Start] > [All Programs] > [Windows Update].
      Please note: When the Windows Update Page is connected and the
      “Security Alert” window pops up, select “Yes.” The “Security Alert”
      window will not pop up for users who have already applied
      Windows  Update.
   2. Select [Express].
   3. Once the Windows Components Upgrade Screen appears, select   “Install updates” to update your system.
   4. In some cases, a system restart may be required. If a message is displayed to tell you that the system needs to be restarted, please reboot, because the patches for security vulnerabilities will be implemented only after system rebooting.

Some malicious codes must be repaired in safety mode because many execution files may be infected, and some of them have self-protection
features. If they cannot be repaired entirely, even with the latest
version of the engine, it is recommended that you boot the system in
“Safety Mode (Use Network)” and scan/repair viruses.

This does not apply to customers who are using MyV3 or Spyzero ASP in Windows 98 or Windows ME.

How to Boot the System in Safety Mode

1. Restart the computer.
2. When the system starts booting, press the [F8] key on the keyboard
   repeatedly. Press the key a number of times.
3. Select “Safety Mode (Use Network)” in the “Windows Advanced
   Option Menu”, using the up/down arrow keys and press “Enter.”
   For reference, if the “Safety Mode” option is selected, Windows wil start using only those drivers necessary for loading minimal devic drivers and services.
4. When the phrase “Safety Mode” is displayed at the bottom of the
   screen, it means that the system booting has been completed in
   safety mode.
5. Once the booting is completed, execute V3 or SpyZero to inspect the system and scan/repair viruses
