I've got this mess that people have been having trouble with.
Avast keeps reporting the random named trojan horse alerts with win32:downloader/malware gen.
Adobe flash player keeps trying to force update and im worried it might be fake.
Services.exe is using up 40% CPU
lots of services like windows firewall are completely nonfunctional.
I had this same virus before and it took me forever to get off. I think I got it back when i torrented an ebook. After that the adobe flash player downloads started popping up for no reason.
Help is greatly appreciated.
Logs are attached

Hi,
Let me look these over. :)

Hi,
**WARNING**Unfortunately one or more of the infections I have identified are Backdoor Trojans, IRCBots or other Malware capable of stealing very important information. You need to stop using all Internet Banking sites, change passwords to all sites with sensitive information from a clean computer and phone your bank to inform them that you may be a victim of identify theft. More often than not, we advise users that a full reinstallation of their Operating System is the only way to ensure that their computer will ever be 100% clean again.
Unfortunately I have found what is known as the ZeroAccess rootkit on your system. It is an especially nasty infection that can take quite some time to clean as well as may have damaged your system files itself. As a warning, during the cleaning (if you choose to do so) you may lose internet access with this computer and in the end we may need to reinstall the operating system anyway depending on the extent of the infection.
If you would like to format and reinstall your Operating System please let me know and we can assist you with that.
If you would like to continue with the cleaning, please continue with the following instructions and I will be more than happy to help. :)
----------
Please download and run ERUNT (http://www.snapfiles.com/get/erunt.html) (Emergency Recovery Utility NT). This program allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed. **Remember if you are using Windows Vista as your operating system right-click the executable and Run as Administrator.
----------
If you are running Malwarebytes 1.6 or better, please disable it for the duration of this run.
To disable Malwarebytes
- Open the scanner and select the Protection tab
- Remove the tick from "Start Protection Module with Windows" as seen below

If you get a message saying "Illegal operation attempted on a registry key that has been marked for deletion", please restart your computer.
--------------------------------------------------------------------
IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here (http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216)

Right-Click and Run as Administrator on ComboFix.exe & follow the prompts. When finished, it will produce a report for you.
- Please post the C:\ComboFix.txt for further review.
----------

ok I'll get started on this tomorrow, I'll try this before reinstalling or reformatting. I'm worried about that stuff, I don't have any experience with it. I have recovery disks but no windows 7 disk.
-
ok my malwarebytes trial had expired so it didn't have an option for the protection. Here are OTL logs, the one with all the numbers showed up when I rebooted after the fix, the second one is a scan. I didn't know if you wanted me to send you these before I did the combofix or what but I'll go ahead and do it.
-
The combofix file is too large to post here, what should I do? Also, thanks for your help and sorry about the wait.
-
Go ahead and run ComboFix. :) Attach the log that is made.
-
I think we cross posted. Please just attach the log. :) No worries about any wait....I had some troubles with my system and just got back online.
-
The file was too big to attach so I split it up into two parts.
-
The second part...and looks like I need a third part...sorry

Here is the log
-
Good...much better. :)
I see that you have both Webroot and Avast running on the same system. Having more than one antivirus program running at once can cause problems with the performance of your system as well as even leaving you less protected. I would recommend removing either Webroot or Avast.

You have an older version of Adobe Reader. You can download the current version HERE (http://www.adobe.com/products/acrobat/readstep2.html)
You may want to consider Foxit Reader (http://www.foxitsoftware.com/downloads/index.php) instead. It may be a bit lighter on resources.
Visit their support forum
Foxit Forum (http://www.foxitsoftware.com/bbs/forumdisplay.php?f=3)
In either case you should uninstall Adobe Reader 9 first. Be sure to move any PDF documents to another folder first though.
----------
In your next reply please attach the OTL logs and let me know how your system is running.

A couple days ago I got another virus. It was an FBI randomware viruse that locked up my computer. I got it off but the registry may still have remnants

Much better. How is everything running?

-
First open an elevated command prompt > Click Start and type cmd in Start Search.
When cmd.exe populates above, right click it and select Run as Administrator to open an elevated command prompt.
Copy/paste the following into the Command Prompt and press Enter...
chkdsk /r
Follow any prompts and when complete reboot your system and let me know how your system is running.

i had to reboot to run chkdsk but i walked out of the room and came back and the desktop was open so i dunno if it ran or not. Its going a little faster i noticed.
-
Ok good. Give it a good run around and let me know how it is running later. :)

Hi,
Good job getting that ran. Please run new scans with Malwarebytes and ESET and attach the new logs. How is your system running?
-
My system is running really slow and laggy after making those changes Svchost is still going crazy and I uninstalled webroot and emisoft before doing the fix in recovery. Firefox is particularly laggy.
-
Hi,
Your system may still be infected and we may need to dive back in. I have not seen as many instances of the ZeroAccess rootkit on one machine before. Dealing with one will normally cause damage but there were many rootkits that had to be cleaned and there may be quite a bit of damage that we have to deal with.

Run a new scan with Farbar Service Scanner and attach the new log. Also let me know how your system is running.

Sorry for the wait again. After doing the fix nothing seems to have changed much. System still gets slow with firefox and svchost uses up memory. I just cancel the process acouple of times and it goes away for a while. booting takes a while but not seriously long. It's just really easy for programs to say "Not responding" and its annoying. Like firefox has done that 3 times for a couple seconds at a time just typing this to fast for it to catch up.

Dunno what the deal is today and last night but it just started going really slow. Takes 7-8 min to boot and locked up a lot, just stopping working.
