A few days ago I realized my pc was infected by viruses/malware. Sound commercials would be heard, end and then start again after a while. I first run Avast and MalwareBytes AntiMalware and they detected threats [MDE-B][Susp], Zwangi, malicious URL blocked globalroot\systemroot\svchost.exe, and others. Every one in a while, Avast would block some numeric website.

After searching on web forums for similar situations, I ran a few things such as ComboFix, TDSSKiller, bootkit remover, exe helper, rkill and maybe others. The result was that I was able to get rid of the sound commercials, which I found out came from a file called Svchost.exe in the Windows folder. This file would be created again after you deleted it, but after running these tools, they removed Rootkit.Boot.Pihar.c and Olmarik trojans. After doing this I ran other scans by several alternative antivirus, Eset and Panda Online Scanner, and they did not detect anything. Same for Avast on Boot-time scan and malwarebytes.

Anyway, I thought I was clean but I tried to use Firefox and the program would freeze, as it used to happen when I had the infection. I reinstalled it and installed it again and it keeps happening. It doesn't happen with Internet explorer, which is what I'm using now. This makes me think I haven't solved the problem yet. Could anybody help me, please?

Thanks in advance.

Welcome aboard Posted Image

Since you ran Combofix...

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.
