    Hi guys.

    I have a pretty big virus I can't seem to get rid of. Trying to download the classic Tom Hanks film 'Big' I came across a site which has started making my Avira Antivirus program send warning pop ups like mad. There are three differing file types that the antivirus detects and it detects them in different places each time on the computer. When you click 'Deny Access' to one of the pop ups, that popup disappear but another few pop up in its place. This goes on and on and it is impossible to make the pop ups stop.

    After a while the computer gets so slow and bogged down becasue of the popups and become unusable. So, the only way i can actually use my computer is to turn off Avira AntiVirus Guard and use the computer unprotected.

    Incidentally the three virus names that pop up are 'W32/Ramnit.C' virus, 'TR/Starter.y' Trojan and 'EXP/CVE-3020-2568.a' exploit.

    So I did all the steps I could in the READ ME FIRST thread apart from COMBOFIX and RootRepeal. Rootrepeal I did not even try to use as I have windows xp 64 bit version and it says not to. Combofix I tried to use as on your windows xp tutorial it says to, but on the link you provide that explains how to use it on 'bleepingcomputer.com' it says not to if you have xp 64 bit. As you had specified specifically not to use rootrepeal with 64 bit systems but not with combofix I thought I would give it a go. It came up with an error saying my OS wasn't compatible so maybe that's something you want to add to your guide.

    When I have my antivirus switched off the only thing I can notice the virus doing is it redirects me to some random advertising webpages with a lady with her tits out at the top of the page and it has blocked access to certain websites such as 'bleepingcomputer.com' and microsoft support websites.

    I am not sure if the antivirus program is triggering the virus to duplicate itself or that all sorts of bad things are happening when I turn off my virus protection but as my virus protection is off I just can't notice it.

    I am debating changing to a different antivirus program that deals with virus's in a different way (automatically perhaps) because Avira is causing my machine to slow down to a halt.

    One final thing is that before I found this blog I ran Malware bytes quick scan while Avira was on and it deleted some dangerous files but it had no effect. Over 200 Avira pop up boxes appeared for the duration though.

    Then I reinstalled it (renaming it) as part of your guide and it did not find anything this time. I have provided the log for the latest search but I have the other one too if you need it.

    Thanks for your help. I really hope it goes! Don't want to lose all my files....

    Welcome to Major Geeks!

    Let me just warn you ahead of time, if you have a Ramnit infection ( and it looks like you do based on what I see), the odds are very high that you will have to reinstall from scratch due to the damage that Ramnit can cause and because it can open up backdoors into your computer which represent a major security risk.

    The above being said, let's run two more scans. The first will be fairly quick and the second will take quite awhile.



    Download TDSSKiller from Kaspersky to your directly onto your Desktop
    • Now double click the TDSSkiller.exe file to run it ( if using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor. )
    • If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123tdk.com).
    • Allow the application to run if prompted by Windows or any security programs you have installed
    • It will start the scan and run rather quickly and will notify you of whether anything is found or not.
    • Follow the instructions to delete/quarantine if asks you what to do when if finds something.
    • Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply. (See: HOW TO: Attach Items To Your Post )
    Now run the below and attach the log from ESET

    Using ESET's Online Scanner

    Thanks for your prompt reply. I think I am screwed though.

    I ran the first program and it came up with nothing. Log is attached.

    As with almost all these files the website to download them is blocked. I have been downloading them on a different computer, then converting the .exe files into .rar files so they can be emailed over to the computer with the problem and running it from there.

    I did the same with ESET's online scanner and transferred the special Mozila .exe file. However, when I run it, it runs but cannot update itself. I click 'Start' . It says 'downloading components' but then stops and says 'Can not get update. Is proxy configured?' and stops.

    Just a note that I have been doing all these in normal mode, not safe mode. Once I booted in safe mode and the pop ups didn't happen but it was probably more becasue Avira was off (I'm not sure that it was but this is my guess) in safe mode or , less likely, that the virus wasn't operating in safe mode.

    If I need to reformat my computer e.t.c and start from scratch is there any way I can save some files! Some phots and important documents. I am pretty sur my USB is infected and so don;t want to take that to any other comp. Could I just e-mail it all somewhere or would that risk spreading it. So far I have only been e-mailing TO the infected comp.

    Here is the log.

    Thanks for your help.

    Ramnit can infect ALL executable files and will also infect ALL HTML files. DO NOT backup any executables (i.e, programs, installer programs you have downloaded no matter what the file extension is). Your photos and personally documents may be okay. You could back them up to DVD or to an external drive and scan them later using a clean PC ( just don't run/open any of these backups or reuse until scanned). ESET online scanner does a pretty good job in detecting Ramnit.


    Did you try booting in safe mode with networking to see if you could run the ESET online scan?

    You have other infections besides Ramnit. For example, I see the below in your logs

    Just an FYI if you do reinstall. I suggest you don't reinstall the below and lay off the poker sites.

    Haha, I have installed a lot of poker sites over the years!

    Thanks for your tip on trying to run ESET in safe mode. It is running at the moment and by the looks of it is going to take a VERY long time. It has been stuck on 36% for half an hour but is still scanning files, just very slowly.

    It has detected 33 infected files so far and they are ramnit files. This is the first scanner to actually find Ramnit files aprt from Aviras popups. I hope that it can delete them too. When (if?) it ever finished I will post back here.

    Thanks for your help so far.

    It can find and clean and in some cases it will just quarantine or delete the file. The problem is that since Ramnit infects so many files, as soon as ESET fixes them, another infected file will start reinfecting things. Thus depending on the degree of the infection, a secondary scan will just find the same things and more again. And the same will occur each time you run the scan. Basically what is happening is that the infection is reinfecting everything as fast, if not faster, then you are finding and cleaning. This is one reason why a reinstall is almost always needed. Another reason for the reinstall is that this infection will frequently make your PC very unstable and very insecure.
