Hi Guys,


I'm trying to fix my old man's Toshiba laptop for him as it seems to have become infected with something nasty.  This "something" is causing the computer to run very, very slowly and is stopping access to the internet - the wireless and LAN connections both appear active however Internet Explorer, Firefox, Chrome, software updates etc. are all not working.


I ran Malwarebytes a few days ago which detected and removed a few problems but it still did not fix the speed or internet issues.  Norton 360 has also been running in the background and popped-up saying it had found and removed a virus of some sort.  In my own wisdom and impatience prior to seeking expert advice from here, I downloaded and ran ComboFix which took plenty of time to run but doesn't appear to have fixed the problems - hopefully I didn't do any damage!


The laptop in question is a Toshiba running Windows XP Professional.  I'm trying everything I can to fix it rather than format it given the amount of data / programs I'd have to reinstall upon wiping it clean.


Pretty sure I have the Malwarebytes and ComboFix logs if required.  Happy to run any other logs or provide any other info which may be useful.  Any help you can provide would be greatly appreciated!


EDIT: Forgot to add that Malwarebytes and Norton 360 aren't picking up any problems now even though the abovementioned problems still exist.

Since you have a ComboFix log...please follow Steps 6-8 of the Prep Guide and initiate a new topic in the forum which contains the Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html .


Paste your CF log data into the post, along with the requested DDS log.


Once that is done, this topic will be closed to avoid confusion.

Your log(s) is posted here.

Now that your log is posted, 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 Malware Response 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(s) you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process or make things worst which would extend the time it takes to clean your computer.

From this point on the Malware Response 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 several days to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response 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 Malware Response Team member is already assisting you and not open the thread to respond.

If HelpBot replies to your topic, please follow Step One and CLICK the link so it will report your topic to the team members.

To avoid confusion, I am closing this topic.

Good luck with your log.
