Infected with CoolWWWSearch - What should I do?

I believe my computer is infected with coolwwwsearch, and possibly something else as well. (Last week Avira found and quarantined TR/Dldr.Mufanom.jfq.1 Trojan and TR/Agent2.cnpy Trojan, which I believe is how I got coolwebsearch). I attempted to remove coolwwwseach and although SpyBot and Malwarebytes both say it's gone and Avira isn't finding anything either, my google queries are still occasionally being redirected to other websites so I know it's still there. (This only happens very occasionally, not every time, and it's redirecting to random pages, not coolwebsearch.com or whatever.) I had a suspicious svchost,exe trying to connect to the internet (I denied it access through Zonealarm) and after running Spybot etc that stopped happening, but now I'm afraid something else is going on that I don't know about.

I'm running the log programs right now so I can post in the Removal Logs forum but it's going to take over 24 hours for the gmer scan to complete and I'm tearing my hair out over this already.

Can anyone tell me how worried I should be about this? Should I stop using my computer altogether until this problem is fixed? What does coolwwwsearch do beyond redirecting your browser? What personal information does it gather? I have searched all over google and keep finding links that say it's "the most dangerous spyware" but I can't find anything that actually explains in what ways it's dangerous. All I can find is that it's hard to remove because it mutates when you try to remove it.

Can I continue to use my computer as long as it isn't connected to the internet as long as I don't do anything with sensitive information like credit card numbers and passwords? Can it infect data files so that when they're opened the trojan is reinstalled?

That depends on what you are actually dealing with and the logs will show the information needed to make that determination. In the meantime you should disconnect the infected computer from the Internet until your machine is cleaned.

CWS was an older infection which hijacked the browser, installed unwanted bookmarks, changed the home page and redirected to CoolWebSearch.com. Each security vendor uses their own naming conventions to identify various types of malware so it's difficult to determine exactly what has been detected or the nature of the infection without knowing more information about the actually file(s) involved.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/296655/infected-with-coolwwwsearch-and-possibly-mufanom/ 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 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.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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