Hi

A few days ago my PC was infected with what I think is the msa.exe Anti virus virus? I'm not very good with this so finding it hard to explain. I keep having random IE pop ups and a lot of notifications that my files are corrupt (AOL being one) I cant install any programs and every time I try to go and search on all files and folders I have the blue screen of death! I also have a message saying Windows XP cannot find my profile and loads without all my files.

Please can anyone help?

Thanks

Hello escapetbs

Let's see what MBAM finds please download Malwarebytes from here http://www.malwarebytes.org/mbam.php
update it and post it's log back to this thread.
if Malwarebytes will not run please try this
Rename this file:

C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe

to this:

winlogon.exe

Then double-click the renamed file and see if it will run.

Regards

D_N_M

Ok, we got some trojan downloaders out. Next:

Please run ATF and SAS:
Credits to Boopme

Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note 2: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Edition

Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.

In that case, you need to run sfc /scannow. Make sure that you have your Windows XP CD availiable in case any files need to be replaced.

Please go to Start, Run. Then in the box, type sfc /scannow. Please notice the space between the c and the /. This will check the system files to make sure that all of them are in proper working order. It may take awhile. When prompted to put in your CD, please insert it.

In the other 3 or 4 threads I have seen this last week with msa.exe, it's been accompanied with a set of backdoor trojan/rootkits which totally take over your computer.

I think sfc /scannow would be a waste of time, if you had a generic windows disk and could stay off the internet you might be able to run a repair disk and get some antimalware programs to work.

One or more of the identified infections is a rootkit/backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

Someone may still be able to clean this machine but we can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

No. Try not. Do... or do not. There is no try.

That doesn't sound good :thumbsup:
Pop ups seem to have gone and PC is running ok, its just I have notifications of corrupt files now and again in the task bar and I had to make another user as my profile wouldn't load when I restarted one time though I have found my files just need to get them backed up.

Ok, and then a reformat would probably be the best choice. Sorry it had to turn out this way. :thumbsup:
