Windows 7: microsoft security essentials not working and windows update error

Backdoor:Win32/Pasur!rt <--- this is a 'backdoor Trojan' .... here's some information about this type of Trojan:

These are the most dangerous, and most widespread, type of Trojan.
Backdoor Trojans provide the author or ‘master’ of the Trojan with remote ‘administration’ of victim machines. Unlike legitimate remote administration utilities, they install, launch and run invisibly, without the consent or knowledge of the user. Once installed, backdoor Trojans can be instructed to send, receive, execute and delete files, harvest confidential data from the computer, log activity on the computer and more.

If your computer was used for online banking or has credit card information on it, all passwords should be changed immediately to include those used for email, eBay and forums.
You should consider them to be compromised.

They should be changed by using a different computer and not the infected one, if not an attacker may get the new passwords and transaction information.
Banking and credit card institutions should be notified of the possible security breech.

ok this scan could take a few hours. Am I correct in thinking this backdoor trojan would have edited the webemtest configuration so I cant use it?

I think I know the program the backdoor trojan was in. I deleted the folder that had the trojan. Also I never installed this program directly.

It is now deleted from my recycle bin, and I would hope that microsoft security would not identify it on a full scan.

Should I restore my system to about a week ago when the file was downloaded having deleted it now, run MSE and delete it in safe mode, or should I continue with what we are doing here which I assume is something like locating any rootkits.

and thanks, so far this has helped me out alot.

I think the scan could take 2 days.

Shouldn't take that long as less your hard drive is a TB .

After we are clean we will delete your system restores and create a new one .

sounds good, anything to avoid re-installing because it would take me at least a week working full time to get back to how it 'was' running.

thanks guys

Once that is done run

TDSSKILLER

download link TDSSKiller

Save to the Desktop

Right-click the program and select


When the TDSSKiller console opens, click on: Change Parameters
Under Additional Options, place a check in the box next to: Detect TDLFS File System

Click: OK


Press: Start Scan


If a suspicious object is detected, the default action is Skip, leave it as is, and click on: Continue
If malicious objects are found, they show in the Scan results.
Ensure Cure (the default) is selected, then click: Continue > Reboot now, to finish the cleaning process.
(Note: If Cure is not available, select Skip, >>Do not select: Delete<<)


When done, the tool outputs its log to the disk with the Windows Operating System, normally C:\


Logs have a name like:
C:\TDSSKiller.X.X.X_12.04.2013_15.31.43_log.txt


Please post the TDSSKiller log in your reply.

When the scan completes, click List Threats
Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
Click the Back button.
Click the Finish button.
Should I at any point delete what has been listed, will it give me that option. Sorry I should have this file soon. I cancelled two scans by mistake.

Today it was an attempt to update Microsoft Security Essentials. Error code 80070005. Aaaaarrrggghhh
Windows Updates & Activation
Windows XP Microsoft Security Essentials Available via MS Update
So today, I decided to patch up my Windows XP netbook and came across Microsoft Security Essentials in the Software section. I thought Windows XP End of Support (April 8) was the day that MS would stop providing downloads for MSE, so I wondered if it was just an installer, so I checked the update...

Firewall is not blocking MSE for sure. Internet connection is perfectly fine. Tried googling for some answers but nothing much about MSE. Does anyone have an answer?

Microsoft Security Essentials Stops Working
For several weeks MSE stops working and either will restart or must be manually restarted. I have been unable to repeat the event. It happens after a boot, and / or spontaneously. I have this error report which means nothing to me. Can anyone make sense of it? Thanks Richard

Microsoft Security Essentials Update Utility
One disadvantage of Microsoft Security Essentials (MSE) is that it uses Windows Update to update the virus definition files. If you disabled the Windows update for some reasons MSE won’t update anymore. The MSE Update Utility can be used here to update MSE even if Windows Update is disabled.
