Thank you ALgal,

I will follow these directions shortly.

Regarding the trusted zones- when I found this virus I turned the security way up for the Internet zone.  Then as the sites I needed in the next few days stopped functioning, I put them one at a time into the trusted zones to allow their ActiveX controls and scripts to be run.

Is their a better way to handle this?

Thanks,
Mike

• 
  
• Go > start > run and type cleanmgr and click OK
  
• Scan your system for files to remove.
  
• Make sure Temporary Files, Temporary Internet Files and Recycle Bin are the only things checked.
  
• Click OK to remove those files.
  
• Click Yes to confirm deletion.
  

• 
  Turn off System Restore.
  
• On the Desktop, right-click My Computer.
  
• Click Properties.
  
• Click the System Restore tab.
  
• Check Turn off System Restore.
  
• Click Apply, and then click OK.
  

• 
  
• On the Desktop, right-click My Computer.
  
• Click Properties.
  
• Click the System Restore tab.
  
• UN-Check *Turn off System Restore*.
  
• Click Apply, and then click OK.
  

• 
  
• Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.
  
  
  See this link for a listing of some online & their stand-alone antivirus programs:
  Virus, Spyware, and Malware Protection and Removal Resources
  
  
  
• Update your AntiVirus Software - It is imperative that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.
  
  
  
• Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a Firewall in its default configuration can lower your risk greatly.
  For a tutorial on Firewalls and a listing of some available ones see the link below:
  Understanding and Using Firewalls
  
  
  
• Test your Firewall - Please test your firewall and make sure it is working properly.
  Test Firewall
  
  
  
• Visit Microsoft's Windows Update Site Frequently - It is important that you visit Windows Updates regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.
  
  
  
• Visit the Microsoft Office Update Site Frequently-If you are running Microsoft Office, or any portion thereof, go to the Microsoft Office Update site and make sure you have at least all the critical updates installed (Free)
  
  
  
• Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option. This will provide realtime spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an antivirus software.
  A tutorial on installing & using this product can be found here:
  Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers
  
  
  
• Install Ad-Aware - Install and download Ad-Aware. ou should also scan your computer with program on a regular basis just as you would an antivirus software in conjunction with Spybot.
  A tutorial on installing & using this product can be found here:
  Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer
  
  
  
• Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.
  A tutorial on installing & using this product can be found here:
  Using SpywareBlaster to protect your computer from Spyware and Malware
  
  
  
• Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
