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.

A trojan could do anything . Yes the scan could take a while .

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 .

Once that is done run
