Adware deletionWhen I ran my McAfee scan, it associated two files with Adware-Virtumondo: setupd.exe and _update.dat.I removed the files by going in to the "safe mode and command only" option of the safe mode start menu.
It gave me a c:\>
At the prompt I changed to the directory where the files were located (c:\>CD windows)
At the new prompt I deleted the setupd.exe file (c:\windows>del setupd.exe)
Then I changed directories again to where the second file was: (c:\windows>CD temp)
At the new prompt I then deleted the second file (c:\windows\temp>del _update.dat)
I then rebooted my computer and the adware-virtumondo files are now gone.
More input from FAQ Farmers:
I filed a complaint demanding immediate removal of my email address and adware receiving from their database. My system was clearded in a day. That was one week ago and I haven't seen anything since.

ATF Cleaner, and AVG Anti-Spyware from the links on the page below....Follow the instructions to run both from that page. (Do not forget to update the AVG Anti-Spyware immediately). Go to post #15 on the first page of 5 pages there...The bottom post!
http://www.cybertechhelp.com/forums/...d.php?t=135442
After quarantineing the files keydll.exe & lldyek.dat w/ the AVG Anti-Spyware, dump the files finally using that tool.
The viral processes will now be finally killed...Now all that is left is to go get rid of the leftover keys in the registry. I used CCleaner.exe for this;
http://www.ccleaner.com/update/?v=1.34.407&l=1033
Install it,
Run Cleaner repeatedly until it removes 0 bytes.
Run Issues, Scan for Issues, Fix all Issues found, always backup the changes by creating a CCBackups folder in My "Documents",
1 key you will find on the first pass will be; C:\DOCUME~1\Locals\Temp\lldyek.dat (the nasty re-creator of the keydll.exe file and that key will finally be deleted. Dump any file found using a drive search by the names in the very second paragraph of this post. (keydll.exe, lldyek.dat, or both using the file extension of .config or .bak).
Scan for Issues again until clean (No Issues Found).
Then check the Start-Up Folder by using the Tools Function of CCleaner, then the Startup Button. highlight and delete *keydll.exe if present there. Also cleanup other entries you wish in the Startup folder using that tool. (***NOTE: look up the files first using a Yahoo or Google search first if you don't know what they are).
It should be clean of that nasty offending beast. Now use Spybot S&D 1.4.exe, Bazooka Scanner.exe from Kephyr.com, SpywareBlaster.exe, and Ad-AwareSE Personal.exe from Lavasoft and get the rest of the spyware out.
Lastly Run HijackThis and delete any item there referring to the above listed files...They will be listed as "(file missing)" which is a good sign...an 02 BHO, and a 20!
Good Luck!

How do you install an anti-virus?
If you have internet access you download the file from the anti virus website and run it.
Or
If you have a CD you insert it into the drive and follow the instructions on the screen
To evade detection, during and after installation, malware uses five primary techniques.
Wrapping. This process attaches the malicious payload (the installer or the malware itself) to a legitimate file. When the legitimate file is installed, so is the malicious payload (which usually installs before the legitimate file does). Using static signatures to detect wrapper files is largely ineffective since new ones are easily and regularly created and often generates false positives. This technique is commonly used by Windows and OS X malware distributed via pirated software and P2P networks. IceFog is a well-known malware commonly wrapped with a legitimate-looking CleanMyMac application and used to target OS X users. On the Windows platform, OnionDuke has been used with legitimate Adobe installers shared over Tor networks to infect machines.
Obfuscation. This involves modifying high level or binary code it in a way that does not affect its functionality, but completely changes its binary signature. Obfuscation was originally used to protect legitimate software against reverse-engineering and piracy. Malware authors have adopted the technique to bypass antivirus engines and impair manual security research. Using XOR encoding is one way to do this. Hiding process and file names, registry entries, URLs and other useful information can significantly slow down the investigation/reverse engineering of new malware samples.
Packers. These software tools are used to compress and encode binary files, which is another form of obfuscation. At runtime, the packer, which is typically embedded with the malicious binary, will "unpack" the payload into memory and execute it. There are a handful of common packing mechanisms in use today such as UPX, PECompact, Armadillo and others. These techniques are extremely effective at circumventing static signature engines.
Anti-debugging. Like obfuscation, anti-bugging was originally created by software developers to protect commercial code from reverse-engineering. Anti-debugging can prevent a binary from being analyzed in an emulated environments such as virtual machines, security sandbox, and others. For example, the ZeroAccess malware implemented a self-debugging technique in order to block external debugging attempts. Another example is malware attempting to delay its execution (or sleep) for an extended period of time. This is useful for bypassing sandboxing solutions since these only keep binaries in an emulated environment for a specific period of time before classifying them as benign and releasing them to the network.
Targeting. This technique is implemented when malware is designed to attack a specific type of system (e.g. Windows XP SP 3), application (e.g. internet Explorer 10) and/or configuration (e.g. detecting a machine not running VMWare tools, which is often a telltale sign for usage of virtualization). Targeting ensures that the malware is only triggered and installed when specific conditions are met, which enables it to evade detection in sandboxes because they do not resemble the host being attacked.

There could be several causes that a computer can abrubply shut down. Cause 1:
Stuffed with lot of Videos/Softwares etc in C:/ especially could cause your RAM Memory to go low. As a result of which, the computer might slow down and gradually shut down. In such cases, try increasing the virtual memory ....but see that while increasing it shouldn't increase your max memory allotted. Cause 2:
It could also be because your computer can have bad sectors. So, see that once in a month, you run scan disk especially C:/ Drive. Cause 2:
Maybe one or more of your vital files that are supported for your smooth running of your major programs in your computer might be deleted. This deletion occurs when specific viruses could delete such files. So, see that the softwares or the programs you install is not from an unauthorized site. You can download softwares from their official sites itself. To my knowledge these are some of the reasons y a computer can shut down abruptly. Jeet
