    Need help in removing sh4ldr from C: caused by a virus
    « on: February 25, 2012, 09:03:56 PM »
    I removed the functionality of the virus for the most part by sweeping ComboFix on it, but unable to remove it entirely as I restored my computer to the day before I got it, but didn't remove it. It was from a variant of the Win7 Security 2011 virus.

    Here is the HiJackThis you're wondering.

    Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

    1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
    2. The fixes are specific to your problem and should only be used for this issue on this machine.
    3. If you don't know or understand something, please don't hesitate to ask.
    4. Please DO NOT run any other tools or scans while I am helping you.
    5. It is important that you reply to this thread. Do not start a new topic.
    6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
    7. Absence of symptoms does not mean that everything is clear.

    If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.

      I have a quick question before I do that. SuperAntiSpyware is not an antivirus, correct? Would it interfere with ESET NOD32 when I don't command it to do a PC sweep?

      SAS is an anti-malware program and it shouldn't interfere with ESET NOD32
