Thank you for your help. My computer has been re-installed by our computer lab. Thanks very much.

Sorry to hear that.

Here are some prevention tips.

Keep your system updated

Microsoft releases patches for Windows and Office products regularly to patch up Windows and Office products loopholes and fix any bugs found. Please ensure that you visit the following websites regularly or do update your system regularly.

Install the updates immediately if they are found. Reboot your computer if necessary, revisit Windows Update and Office update sites until there are no more updates to be installed.

To update Windows

Go to Start > All Programs > Windows Update

To update Office

Open up any Office program.

Go to Help > Check for Updates

Alternatively, you can visit the links below to update Windows and Office products.

Windows Update
Office Update

If you are forgetful, you can change some settings so that you will be informed of updates. Here's how:

  1. Go to Start > Control Panel > Automatic Updates
  2. Select Automatic (recommended) radio button if you want the updates to be downloaded and installed without prompting you.
  3. Select Download updates for me, but let me chose when to install them radio button if you want the updates to be downloaded automatically but to be installed at another time.
  4. Select Notify me but don't automatically download or install them radio button if you want to be notified of the updates.


Besides Windows that needs regular updating, antivirus, anti-spyware and firewall programs update regularly too.

Please make sure that you update your antivirus, firewall and anti-spyware programs at least once a week.

Be careful when opening attachments and downloading files.

  1. Never open email attachments, not even if they are from someone you know. If you need to open them, scan them with your antivirus program before opening.
  2. Never open emails from unknown senders.
  3. Beware of emails that warn about viruses that are spreading, especially those from antivirus vendors. These email addresses can be easily spoofed. Check the antivirus vendor websites to be sure.
  4. Be careful of what you download. Only download files from known sources. Also, avoid cracked programs. If you need a particular program that costs too much for you, try finding free alternatives on Sourceforge or Pricelessware.


Surf safely

Many of the exploits are directed to users of Internet Explorer and Firefox.

Using Firefox with NoScript add-on helps to prevent most exploits from running as NoScript by default disables all scripts on all websites. If you trust the website, you can manually allow it.

If you prefer to use Internet Explorer, here are some settings to change to improve the security of Internet Explorer.

For Internet Explorer 6

  1. Open Internet Explorer. Click on Tools > Options.
  2. Click on the Security tab.
  3. Click on the Internet icon.
  4. Click on the Custom Level button.
  5. Under Download signed ActiveX controls, select Prompt.
  6. Under Download unsigned ActiveX controls, select Disable.
  7. Under Initialize and script ActiveX controls not marked as safe, select Disable.
  8. Under Installation of desktop items, select Prompt.
  9. Under Launching programs and files in an IFRAME, select Prompt.
  10. Under Navigate sub-frames across different domains, select Prompt.
  11. Under Allow paste operations via script, select Disable.
  12. Click OK to apply these settings.
  13. If it prompts you as to whether or not you want to save the settings, press the Yes button.
  14. Press OK to exit the Internet Properties page.


For a pictorial guide, please refer to this article.

For Internet Explorer 7

If you want to upgrade to Internet Explorer 7, please read this article to configure Internet Explorer 7 properly.

Stop malicious scripts

Windows by default allow scripts (which is VBScript and JavaScript) to run and some of these scripts are malicious. Use Noscript by Symantec or Script Defender by AnalogX to handle these scripts.

Backup regularly

You never know when your PC will become unstable or become so infected that you can't recover it. Follow this Microsoft article to learn how to backup. Follow this article by Microsoft to restore your backups.

Alternatively, you can use 3rd-party programs to back up your data. One example can be found at Bleeping Computer.

Avoid P2P

P2P may be a great way to get lots of stuffs, but it is a great way to get infected as well. There's no way to tell if the file being shared is infected. Worse still, some worms spread via P2P networks, infecting you as well. If you do need to use them, use them sparingly. Check this list of clean and infected P2P programs if you need to use one.

Prevent a re-infection

  1. Winpatrol
    Winpatrol is heuristic protection program, meaning it looks for patterns in codes that work like malware. It also takes a snapshot of your system's critical resources and alerts you to any changes that may occur without you knowing. You can read more about Winpatrol's features here.

    You can get a free copy of Winpatrol or use the Plus version for more features.

    You can read Winpatrol's FAQ if you run into problems.

  2. Spyware Blaster
    SpywareBlaster is a program that is used to secure Internet Explorer by making it harder for ActiveX programs to run on your computer. It does this by disabling known offending ActiveX programs from running at all.

    You can download SpywareBlaster from Javacool.

    If you need help in using SpywareBlaster, you can read SpywareBlaster's tutorial at Bleeping Computer.

  3. SpywareGuard
    Just as an antivirus program scans a file for viruses before opening it, SpywareGuard does the same thing, except that it scans it for spywares.

    You can download SpywareGuard from Javacool.

    If you need help in using SpywareGuard, you can SpywareGuard's tutorial at Bleeping Computer.

  4. IE-SPYAD
    IE-SPYAD adds over 5000 sites to your Internet Explorer restricted zone so that you will be protected if the website turns out to be a bad one. Sites that are in the restricted zone of Internet Explorer can't have any scripts ran, no downloads and cookies. However, you can still connect to these sites.

    You can download IE-SPYAD from Spyware Warrior. Be sure to read the whole website carefully for instructions on usage of IE-SPYAD.

  5. Hosts File
    A Hosts file is like a phone book. You look up someone's name in the phone book before calling him/her. Similarly, your PC will look up the website's IP address before you can view the website.

    Hosts file will replace your current Hosts file with another one containing well-known advertisement sites, spyware sites and other bad sites. This new Hosts file will protect you by re-directing these bad sites to 127.0.0.1.

    Here are some Hosts files:

    MVPS Hosts File
    Bluetack's Hosts File
    Bluetack's Host Manager
    hpHosts

    A tutorial about Hosts File can be found at Malware Removal.

  6. Spybot Search and Destroy
    Spybot Search & Destroy is another program for scanning spywares and adwares. Not only so, it has other preventive options as well. You are strongly encouraged to run a scan at least once per week.

    Spybot Search & Destroy can be downloaded from here.

    If you need help in using Spybot Search & Destroy, you can read Spybot Search and Destroy tutorial at Bleeping Computer.

  7. a-squared Free
    a-squared Free is also another program for scanning spywares and adwares. It doesn't have preventive features like Spybot Search & Destroy though.

    You can download a-squared Free from here.

    Before downloading any anti-spyware programs, always check the Rogue/Suspect list of anti-spyware programs and Malwarebytes RogueNET. This will save you from a lot of trouble. If in doubt, don't ever download it.

  8. SiteHound Toolbar
    SiteHound is a toolbar that warns you if you go to a site that is known to scam people, that has potentially lots of viruses or spywares or has questionable contents. If you know the site, you can enter it; if you don't, it will bring you back to the previous page. Currently, SiteHound works for Internet Explorer and Firefox only.
