How Can You Remove A Trojan.zlob From Your Computer, If Your Antivirus Can’t Remove It For You?
Posted on 22nd October 2009
After trying to download an upgrade for a Video ActiveX Access, I got a Trojan.Zlob. This specific Trojan allows the remote attacker to perform various malicious actions on the compremised computer. The file name is called iesplg.dll. It is impossible to remove it the traditonnal way with the program available in the control pannel, nor with the help of my Norton Antivirus. How can I get rid of this virus with rebboting my whole computer?

Try a online antivirus scanner and a online anti-adware/malware/spyware scanner in safe mode with network to clean up your computer BEFORE you download anything. This because the program you download can get infected.
Disable “System Restore” for Windows Me and XP, then restart your PC to clean your system restore points for viruses, spyware, adware etc.http://www.microsoft.com/technet/communi…
Now restart in safe mode.
To get in safe mode Press “F8″ upon boot up.
Select “Safe mode with Network”.
Go to Start – Run - type iexplore http://www.bitdefender.com/scan8/ie.html Enter(ok).
Do a full scan of all your drives. If something is found, delete it, reboot and do the same again in safe mode with network.
When that scan does not find anything you reboot again in safe mode with network.
Go to Start – Run – type iexplore http://www.ewido.net/en/ Enter(ok).
Do a full scan of all your drives. If something is found, delete it, reboot and do the same again in safe mode with network.
**NOTE**: Do NOT do anything else with your computer when scanning. This because you can start virus/adware/spyware/malware manually.
When no one of these scanners are showing anything you can reboot back to normal mode.
Turn on “System Restore”.
—————
Antivirus: BitDefender Online scanner - will scan and remove threats.
Anti adware/spyware: Ewido Online Scanner - will scan and remove threats.
—————
**NOTE**: Only have one antivirus program and one firewall installed on your computer.
Anti-adware/malware/spyware are ok to have more off.
You need to get one antivirus program, one firewall, pop up blocker and some spyware/adware/malware removers if you don’t have it.

I use this and more on my Windows XP Home SP2 computer:
BitDefender Antivirus (Real Time): http://www.bitdefender.com/no/view/Downl…

CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. http://www.ccleaner.com/
All are free.
**NOTE**: Only have one antivirus program and one firewall installed on your computer.
Anti-adware/malware/spyware are ok to have more of.
Good Luck.

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Run a full system scan and delete all the files detected.
Delete any values added to the registry.
Reset the Internet Explorer home page.
Reset the Internet Explorer search page.
For specific details on each of these steps, read the following instructions.
1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.
Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.
Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

First, turn OFF System Restore. If you leave it on and you have to Restore your puter later, you’ll just re-infect the thing!!!
Second, go to this site and USE it! :::http://support.f-secure.com/enu/home/ols…
You want to do this because your onboard anti-malware progs may be infected, too. Once you know they’re clean THEN Update and Run them!
Then, if you want/need to you can follow spywaredr’s (Answer 5) LONG list of suggestions.

try GarbageClean antispyware from http://www.SecureMyWindows.com to remove Zlob
October 22nd, 2009 at 2:28 am
One of your problems is you are using Norton.
The other is that Trojan may not be a Virus it may be Spyware and Anti Virus programs will not remove SpyWare.
Try AD-Aware 2007 and SpyBot Search and Destroy to clean out the Spyware. They are both free programs.
For a Free anti virus program, when you get tired of paying good money to Norton, use AVG Free or AVAST. They both are higher rated than Norton.
October 22nd, 2009 at 2:40 am
AntiSpyware Programs normally remove Trojans!
AVG AntiSpywarehttp://www.free.grisoft.com
Emsisoft A-Squared 3.0http://www.emsisoft.com
Ad-Aware 2007http://www.lavasoft.com
Comodo BOCleanhttp://www.comodo.com
Also download the free version of BitDefender. This is like a back-up antivirus..
It is compatable with most, for the reason being that it does not protect, but only scan, update, remove and quarantine.

Superantispyware constantly adds zlob variants to its database, so Superantispyware should remove it:http://www.superantispyware.com/
In the event that Super… doesn’t remove your particular zlob trojan, then Roguefix definitely will:http://www.internetinspiration.co.uk/rog…

Ha! This happened to me.. Say goodbye to music files, pics, and everything else. What you’ll have to do is find your original restore disks that came with your computer and just run them through. ALSO AND MOST IMPORTANT dont even think about trying to put ure files onto a usb drive. Youll transfer the virus right back to your cpu. Just run the disks through and it will be fine.

For info and removal see link below.
download free 30 day trial
hope this helps.

Do yourself a favor and please don’t listen to the people telling you to run all sorts of antivirus. There is absolutely NO way to be sure that everything has been removed. When someone creates a malicious program, they test it against all sorts of antiviruses before they release it. Backup documents, restore the computer. It’s really the only way, don’t set yourself up for the same thing down the road… or a stolen identity.

Spy Sites
Stop Web Sites from installing Spyware, Sleazeware and Cookies on your PC
SpySites includes a database of over 4,600
known Spy/Sleaze sites and guides you
through the simple process of including them in
Internet Explorer’s Restricted Zone and setting policies
to prevent them from performing intrusive acts on your PC.
By setting the policies for the Restricted
sites zone to a very high level of security,
you can be assured that any web sites added
to the Restricted sites zone cannot do
certain things which could compromise your privacy
and security such as installing and/or running:
Spysiteshttp://camtech2000.net/pages/spysites_pr…
Pre-Fetch File Cleaning
pre-fetch files are “cached” or stored copies of files/websites you visit each session
after a period of time,these files hog up a LOT of disk space
for this reason,i advocate the deletion weekly of those space hogs
some claim that windows will automatically remove files older than 7 days
I have found MY pc does NOT perform this task so I do it manually
what happens is,when you go to a website,your pc looks into your pre-fetch file/folder
to see if that website is “cached”,stored there FIRST
this gives you a faster website load,BUT,you get the “cached” version and NOT the NEWEST version
unless you have “check for newest version” checked in internet options
it may take that website 1/2 a second longer to load
but,you’ll get the newest version loading each time
as added security,spyware removers often miss these files,so delete them manually.
My Computer,disk drive [c],windows,pre-fetch,view,select… all,select delete
same situation with Temp files:
Temp File Folder
i use Disk Clean to clean up extraneous files i no longer need
however,every time i use Disk Clean,it DOESN’T clean out Temp Files!
solution?
My Computer,local disk drive [c],windows,temp
you can safely delete each temp file there.
i leave the most current [that day] alone.
also,do not delete any FOLDER there
folders have a folder icon,leave alone
[ Vista,it's Computer ]
Firefox Web Browser:
tools

check block pop ups
load images automatically:
exceptions:
enter those websites addresses that show up on pop ups that appear AFTER you close a browser window
also add those same urls to
