Hi, I previously posted this to "HijackThis Logs and Virus/Trojan/Spyware/Malware Removal", but it seems that the post cannot catch the guys' attention, I repost here.
Hope that someone can help me out, thx.

Hi,

Hello everyone, I'm new here and my first post is already a malware removal request, I'm not sure if it is against appropriate netiquitte, but pardon me if it seems to be impolite.

I have been suspecting my computer is infected (virus or trojan horse etc), the most obvious symptom is the one in this topic title:

More than 40 of all the running process are consuming 10MB+ of memory, in fact there are 20+ of them which has 20MB+.

To rule out the possibility that all these processes really do need that much memory, I use Skype on two computers and see if there are any differences on the memory use.

Result is:
"Control" computer for comparison: skype uses 14mb
Subject computer under suspicion: skype uses 40mb

So I have reasons to believe that something's wrong.

Another symptom is that Firefox(IE7 also, and, even worse, it frequently freezes) easily climbs up to 140mb+ even if only one tab of page is used. However this might not be a good evidence because several add-ons are installed in FF.

Since the prep guide doesn't suggest to immediately post HJT log, I will have the DDS logs here first.

Would greatly appreciate if help is available on isolating the problem. I'm a developer and I have many apps and dev tools installed, so things might be complicated but I think I do have enough knowings on Win XP and hardware, and to hope that I am able to provide precise information for assistance.

Since you have an open HJT log, please follow only the advice given by the HJT team member who takes your log.

Now that your log is properly 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 HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it 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 very 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.
