My computer has started lagging so after running Avanquest Fix-It and it finding no viruses I deceided to do some searching and found a large number of files in my C folder that started with pos and then different numbers and carried a tmp extension. I searched online for this virus and started to take the steps to correct it but in trying to do so I discovered that I have no firewall control. When I go into the properties for my wireless connection and click on the advanced option it reads:

Windows cannot display the properties of this connection. The Windows Management Instrumentation (WMI) information might be corrupted. To correct this, use System Restore to restore Windows to an earlier time (called a restore point). System Restore is located in the System Tools folder in Accessories.

When I went to do a system restore I found that it was turned off so I have no restore points. So in trying to stop my computer from lagging I see I might have more problems than I knew about. I would like to continue the steps to get rid of the tmp files and get rid of that red 'X' on my C drive but I'm one to follow instructions to the tee so if someone knows how I can start by getting my restore back and my firewall back I'd appreciate it and then perhaps we can move on to eliminating this virus. I am using Windows XP on an Acer Aspire 1640Z laptop. My fiance purchased this laptop from a coworker and now I see why she got it for so cheap. Thanks for any help. --Rick

This is a nasty variant of a vundo infection which creates thousands of pos*.tmp files in the root of the system volume (usually your C: Drive) and puts a Red X on your drive icon as you describe. Deleting the files will only lead to their replacement. The malware may also attack legit programs and create new filenames with space(s) in the name before its extension. Removal will require further investigation and the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log" and complete all the steps. There are instructions for downloading and running Deckard's System Scanner (DSS) which will create a hijackthis log for you, or automatically download and install the most current version of HijackThis if it's not already installed on your computer.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Hello cenzaman,

Now that you have posted your log here: http://www.bleepingcomputer.com/forums/t/149599/infected-with-trojans-vundos-trats-virtumond-and-more/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
