Title: Bad codec install?
Post by: RiesMartini on July 05, 2008, 10:52:34 AM
Hey there. A day or so ago, I was surfing the internet, when I came to a page that asked me to install a file to view a movie. I, not thinking, installed it. Usually I'm very good about avoiding that sort of thing, but I guess I was tired. In result, I earned my first virus (or something) that visually did something to my laptop.

I'm trying hard to remember what it did, exactly, but a lot happened, and even more of it was brief. My background changed itself to a blue screen with a yellow box that said something along the lines of, "Warning! There is Spyware on your computer. Install an antivirus program immediately." Or something. I'd post a screenshot, but after following the Read this before requesting malware removal help forum, it went away. Let's see... My computer slowed down immensely, it would occasionally show the Blue Screen of Death, and the error would always be something different and weird. I can't remember any of them, but they all seemed like something that wouldn't even be on the computer. Every now and then, the blue screen would cause my computer to reboot, and when it loaded back up, I would get a pop-up error saying something about a script error, and M-Dos would run through something quickly (said it was a system32 file?), and I would usually get a BSoD after that too.

I really can't remember anything else. Like I said, everything that happened was quick, so I didn't get much time to ponder or write it all down. I know that all this has caused Firefox to quit working, and for awhile, IE would close itself down after loading the homepage. I was able to get Firefox to work once or twice (I don't know how) but now it just shows a Close Firefox error that says Firefox is already running. Task Manager claims that it is not.

I had run a couple other programs before following "Read this before requesting malware removal help." Spybot and a-squared a couple times. Both found different things. Spybot found zlob.downloader.vcd, but everytime I'd reboot, it'd find it again. A-squared usually found small adware programs that it claimed weren't dangerous.

Other than that, I followed "Read this before requesting malware removal help" to a T, but neither Super Anti-Spyware or MalwareBytes found anything. I'm not sure if I still have the virus, or if it was removed by Spybot or a-squared, and the remaining problems (Firefox still won't boot, computer is very slow, occasional freezes) are just left-overs.

If anything, I would like help getting Firefox to work. It's my main browser, and I feel weird using IE. Besides, one of the times Firefox -did- open, I noticed that my bookmarks had been deleted and I would like to work on getting those back as soon as possible.

And now, the HijackThis log. Thanks for any help you can give me.

Open Hijackthis and select Do a system scan only then place a check mark next to:

O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)

Close all windows except for Hijackthis then click Fix checked.

Exit Hijackthis and run CCleaner.

I hope I did that right.. The tutorial said to download the Windows Recovery thing, but Combofix didn't start installing it (like it said it would) until after it'd been running for a few minutes. But I think it all came out to the same result.

Hm.. Everything seems to be okay now. I was able to open Firefox, which makes me very happy. I don't see anything wrong now..

Looks good.

Let's clear out the programs we've been using to clean up your computer, they are not suitable for
general malware removal and could cause damage if launched accidentally. These steps will also help secure the work you have done.

.
The above procedure will:.
----------

Download OTMoveIt2 by OldTimer  OTMoveIt2.exe (http://download.bleepingcomputer.com/oldtimer/OTMoveIt2.exe) and place it on your desktop. (unless you already have it installed)

1. Double click OTMoveIt2.exe to launch it.
Vista users right click and choose Run As Administrator
2. Click on the CleanUp! button.
3. OTMoveIt2 will download a list from the Internet, if your firewall or other defensive programs alerts you, allow it access.
4. Click YES at the next prompt (list downloaded, Do you want to begin cleanup process?)
5. Once complete exit out of OTMoveIt2

----------

Set a New Restore Point to prevent possible reinfection from an old one
Setting a new restore point AFTER cleaning your system will enable your computer to roll-back to a clean working state if needed.
You can find instructions on how to enable and re-enable system restore here:

Windows XP System Restore Guide (http://www.bleepingcomputer.com/forums/tutorial56.html) or Windows Vista System Restore Guide  (http://www.bleepingcomputer.com/tutorials/tutorial143.html)
.
----------

Use the  Secunia Software Inspector (http://secunia.com/software_inspector) to check for out of date software.
.
----------

Important: You Need to Update Windows and Internet Explorer regularly to protect your computer from the malware and other security threats that are on the Internet. Go to Microsoft Windows Update (http://windowsupdate.microsoft.com/) and get all critical updates.

If you are running any Microsoft Office version go to the Office Update (http://office.microsoft.com/search/redir.aspx?assetid=ES790020331033&CTT=96&Origin=CL100570421033) site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update.

----------

Make sure all of your security programs are up to date and run scans with them regularly. Once or twice a week minimum.

Here are some great FREE tools to help you keep from getting infected again. These tools use little or no resources so won't slow down your PC.

To prevent unknown applications from being installed on your computer install WinPatrol 2008 (http://www.winpatrol.com/winpatrol.html)
 Using Winpatrol to protect your computer from malicious software (http://www.winpatrol.com/features.html)

Another thing I would suggest installing SiteAdvisor (http://www.siteadvisor.com/). SiteAdvisor rates sites on business practices and spam.

 SpywareBlaster (http://www.javacoolsoftware.com/spywareblaster.html) - Secure your Internet Explorer to make it harder for these ActiveX programs to run on your computer. Also stop certain cookies from being added to your computer when running Mozilla based browsers like Firefox.
