A couple of things, could you try downloading this: http://www.sevenforums.com/attachments/tutorials/159134d1312706820-default-file-type-associations-restore-default_lnk_-shortcut-.reg

double click it and allow it to merge with your registry.

Also, please right click your Start Orb > click Properties > click Start Menu > click Customize

Hi gha128,

As it currently stands, both sundavis (a MRT member member who was helping me) and I have ran out of ideas.

If this is your only current symptom, then either it is not related to a malware infection or it is left over problem from an infection which has since been removed.

My only recommendations are:

1. A System Restore - you can roll back your computer to it's state at an earlier point in time without loosing data (though you will lose any programs you installed after that date). You should chose a date which you are sure your PC was running normally. More details here: http://www.sevenforums.com/tutorials/700-system-restore.html

2. A Repair Install - probably best if option 1 doesn't work. This option will completely reinstall Windows, but keep all of your data and programs. More details here: http://www.sevenforums.com/tutorials/3413-repair-install.html

Remember with either of these options, your Windows installation will be taken back to an earlier point in time and so you will need to update it using Microsoft update.

Any questions?

Casey

No problem, I'm only sorry that I wasn't able to resolve the issue.

I'll leave a few preventative steps for you, just to help prevent any infection in the future and then I'll close this topic.

Keep Windows up-to-date
Microsoft continually releases security and stability updates for its supported operating systems and you should always apply these to help keep your PC secure.

  • Windows 7 users
    You should run the Windows Update program from your start menu to access the latest updates to your operating system (information can be found here).

Hiding Hidden Files
Please set your system to hide all hidden files.
Click Start, open My Computer, select the Tools menu and click Folder Options.
Select the View Tab. Under the Hidden files and folders heading, uncheck Show hidden files and folders.
Check: Hide file extensions for known file types
Check the Hide protected operating system files (recommended) option.
Click Yes to confirm.

Practice Safe Internet

One of the main reasons people get infected in the first place is that they are not practicing Safe Internet. You practice Safe Internet when you educate yourself on how to properly use the Internet through the use of security tools and good practice. Knowing how you can get infected and what types of files and sites to avoid will be the most crucial step in keeping your computer malware free. The reality is that the majority of people who are infected with malware are ones who click on things they shouldn't be clicking on. Whether these things are files or sites it doesn't really matter. If something is out to get you, and you click on it, it most likely will. Below are a list of simple precautions to take to keep your computer clean and running securely:
  • If you receive an attachment from someone you do not know, DO NOT OPEN IT! Simple as that. Opening attachments from people you do not know is a very common method for viruses or worms to infect your computer.

  • If you receive an attachment and it ends with a .exe, .com, .bat, or .pif do not open the attachment unless you know for a fact that it is clean. For the casual computer user, you will almost never receive a valid attachment of this type.

  • If you receive an attachment from someone you know, and it looks suspicious, then it probably is. The email could be from someone you know infected with a malware that is trying to infect everyone in their address book.

  • If you are browsing the Internet and a popup appears saying that you are infected, ignore it!. These are, as far as I am concerned, scams that are being used to scare you into purchasing a piece of software. For an example of these types of popups, or Foistware, you should read this article: Foistware, And how to avoid it.

    There are also programs that disguise themselves as Anti-Spyware or security products but are instead scams. For a list of these types of programs we recommend you visit this link: Rogue/Suspect Anti-Spyware Products & Web Sites

  • Another tactic to fool you on the web is when a site displays a popup that looks like a normal Windows message or alert. When you click on them, though, they instead bring you to another site that is trying to push a product on you. We suggest that you close these windows by clicking on the X instead of the OK button. Alternatively, you can check to see if it's a real alert by right-clicking on the window. If there is a menu that comes up saying Add to Favorites... you know it's a fake.

  • Do not go to adult sites. I know this may bother some of you, but the fact is that a large amount of malware is pushed through these types of sites. I am not saying all adult sites do this, but a lot do.

  • When using an Instant Messaging program be cautious about clicking on links people send to you. It is not uncommon for infections to send a message to everyone in the infected person's contact list that contains a link to an infection. Instead when you receive a message that contains a link, message back to the person asking if it is legit before you click on it.

  • Stay away from Warez and Crack sites! In addition to the obvious copyright issues, the downloads from these sites are typically overrun with infections.

  • Be careful of what you download off of web sites and Peer-2-Peer networks. Some sites disguise malware as legitimate software to trick you into installing them and Peer-2-Peer networks are crawling with it. If you want to download a piece of software a from a site, and are not sure if they are legitimate, you can use McAfee Siteadvisor to look up info on the site.

  • DO NOT INSTALL any software without first reading the End User License Agreement, otherwise known as the EULA. A tactic that some developers use is to offer their software for free, but have spyware and other programs you do not want bundled with it. This is where they make their money. By reading the agreement there is a good chance you can spot this and not install the software.

Make Internet Explorer more secure
  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
  • Change the Download signed ActiveX controls to Prompt
  • Change the Download unsigned ActiveX controls to Disable
  • Change the Initialize and script ActiveX controls not marked as safe to Disable
  • Change the Installation of desktop items to Prompt
  • Change the Launching programs and files in an IFRAME to Prompt
  • Change the Navigate sub-frames across different domains to Prompt
  • When all these settings have been made, click on the OK button.
  • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.


Regularly 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. If you use a commercial antivirus program you must make sure you keep renewing your subscription. Otherwise, once your subscription runs out, you may not be able to update the programs virus definitions.


Make sure your applications have all of their updates

It is also possible for other programs on your computer to have security vulnerability that can allow malware to infect you. Therefore, it is also a good idea to check for the latest versions of commonly installed applications that are regularly patched to fix vulnerabilities. You can check these by visiting Secunia Software Inspector and Calendar of Updates.

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.

Follow this list and your potential for being infected again will reduce dramatically.
