Hi, I've been getting alot of pop ups lately from avast saying that it has blocked a malware in my computer, it is always either Win32:malware-gen or Win32:trojan-gen, however when i scanned the computer with Malwarebytes it didnt detect anything.
The pop up is occuring about every 5 minutes even when there are no other programs running

Any help on this would be greatly appreciated.

Ok thanks
ive attached the logs here

And now you wait. Volunteer certified malware specialists live in different time zones, so might be a bit before one comes online for you.

aswMBR.exe scan indicates a problem with a necessary windows file, services.exe, so do not attempt to quarantine or delete this file. Wait for a malware expert to guide you through the process of cleansing this file as the fix proposed will be custom-made just for your system and no other.

I strongly suggest leaving fixing services.exe to the professionals. Follow all instructions to the dot, and you will be in the clear.

Thank you for providing the logs so your expert can assist you.

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL

Under the Custom Scans/Fixes box at the bottom, paste in the following

Code: [Select]

ipconfig /release /c
ipconfig /renew /c

:Commands
[purity]
[resethosts]
[emptytemp]
[CREATERESTOREPOINT]
[Reboot]

Then click the Run Fix button at the top
Let the program run unhindered, reboot the PC when it is done
Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.

THEN

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* 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

Double click on ComboFix.exe & follow the prompts.
Accept the disclaimer and allow to update if it asks

When finished, it shall produce a log for you.
Please include the C:\ComboFix.txt in your next reply.[/b]

Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

FINALLY

run farbar service scanner

Tick "All" options.
Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.

hi essexboy, i tried to run the OTL fix that you provided for me, but when i did, the scan (and my computer) froze. i waited for a while but i was eventually forced to restart the computer.
im not sure what happened but an OTL log appeared when i restarted, i have attached it to the post

i am unsure as to whether this is correct or if i need to run OTL again

essexboy · « **Reply #6 on:** September 17, 2012, 03:25:03 PM »

Go direct to the combofix run now please

Frank.11 · « **Reply #7 on:** September 18, 2012, 10:28:13 AM »

Ok, i have done the combofix scan, logs posted

Frank.11 · « **Reply #8 on:** September 18, 2012, 10:31:12 AM »

i have also completed the farbar scan

essexboy · « **Reply #9 on:** September 18, 2012, 03:41:43 PM »

OTL did its job and combofix finished it off

he is not done yet....so come back later for the cleanup

essexboy · « **Reply #12 on:** September 19, 2012, 03:06:02 PM »

Subject to no further problems

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL

Under the Custom Scans/Fixes box at the bottom, paste in the following
Quote
:Commands
[resethosts]
[emptytemp]
[Reboot]

Then click the Run Fix button at the top
Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK
Follow the prompts on the screen
A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

Go to control panel
Select folder options (Appearance > Folder options in category view)
Select the View Tab.
Under the Hidden files and folders heading select Do not show hidden files and folders.
Click Yes to confirm.
Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

Upgrading Java:

Go to this site and click Do I have Java
It will check your current version and then offer to update to the latest version

SPRING CLEAN

To manually create a new Restore Point

Go to Control Panel and select System
Select System
On the left select System Protection and accept the warning if you get one
Select System Protection Tab
Select Create at the bottom
Type in a name i.e. Clean
Select Create

Now we can purge the infected ones

GoStart > All programs > Accessories > system tools
Right click Disc cleanup and select run as administrator
Select Your main drive and accept the warning if you get one
For a few moments the system will make some calculations
Select the More Options tab
In the System Restore and Shadow Backups select Clean up
Select Delete on the pop up
Select OK
Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?

Keep safe :wave:
