EDIT: Moved from Win7 to Am I Infected..
Hi guys,

I have windows 7 professional 32bit. I guess I have been infected by a Trojan called "sirefef.b". I tried to clean it by Microsoft Security Essential but it can not clean it! Also after that my internet connection has lost and I can not connect to the net any more!

I would appreciate it if you can help me with this problem. This is my university desktop and I don't want to go for installing a new windows.

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
