Over the past two days, my computer has been acting peculiar.

(Before I begin, let me say that I run Microsoft XP with Service Pack 3.)

I started suspecting something when, whenever I started Firefox, it kept on congratulating me for updating to the new version of Firefox. I thought it was just a bug, so ignored it.

Fortunately, I needed to do a Google search, so I caught onto the real distressing part fast. When I do a Google search, it does the search just fine. It's when I go to click on one of the results that things get strange. The link data looks fine, but when I click it redirects me to some other 'search site'. I hit the back button and tried it again a few times. Cleaned the cache after I get the feeling it wasn't working and began playing 'Find the Bad Thing'.

I use AVG Free, Spybot Search and Destroy and Malwarebyte's Anti-Malware. A few tracking cookies came out in one of the early searches (which were promptly removed), and then nothing else. Problem persisted. I installed and ran SuperAntiSpyware, but still nada.

Also, it's worth noting I've been getting blue screens, followed by immediate system restarts.

I'm getting a bit concerned now, since I'm not finding anything. Yet, during one of the redirects, AVG said that it caught some exploit.[The computer restarted a few seconds later, so I couldn't get anything written down.] Since I use this computer for pretty much everything, I'm a bit concerned. Any help would be appreciated.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Your word is law! *salute*

~~~

So, I did as you advised. Restarted in Safe Mode and started the program. Took 3 runs before it completed the 'Complete Test'.

First run -- Quick scan had no problems. Detected a trojan.

C:\windows\system32\drivers\skynetmhrvkmtt.sys: Trojan.Packed 2479

It was unable to cure this infection, so it moved it.

The program ran into some error a few minutes later and was forced to close.

Second run -- Quick scan had no problems. Program was forced to close again.

Third run -- Deleted the folder that the scan was getting stuck on. (It was a game file my friend had given me years ago. Hadn't given me problems before.) Quick scan and Complete scan ran fine. Results are as follows:

RegUBP2b-Administrator.reg;C:\Documents and Settings\All Users\Application Data\Spybot - Search & Destroy\Snapshots2;Trojan.StartPage.1505;Deleted.;

~~~~~

After the program was complete, I restarted. Windows needed to check the disk. I allowed it to and it removed a few entries.

Soon after everything loaded up, I opened Firefox. It's still giving me the greeting. AVG caught 6 iterations of the following:

File: C:\WINDOWS\system32\SKYNETbvqyeigw.dll
Infection: Trojan horse Rootkit-Agent.DZ

I haven't hit the 'Remove selected infections' button, just in case it might move things out of the way Dr.Web left them

Also, tried the Google search and it looks like clicking on links works (for now).

What's next?

P.S. Another iteration of the Trojan AVG caught was detected as I was making this post.

Try running a scan with AVG in Safe Mode.

So, ran AVG. There were a few files not scanned because they were 'Locked files'. Seeing as they were .dat files(like UsrClass.dat, UsrClass.dat.LOG, NTUSER.dat, etc.), I'll assume that's normal? Important thing is that it moved skynetmhrvkmtt.sys from DoctorWeb\Quarantine to the Virus Vault.

As an extra measure, I ran Spybot and Malwarebyte's Anti-Malware while I was still in safe mode. Spybot caught nothing, but Anti-Malware did. Log below.

So, what next? The Google search seems to be working, and I'm not getting the blue screens anymore.

If you’re clean, you should create a new Restore Point to prevent possible re-infection from an old one.

Go Start > Programs > Accessories > System Tools and click System Restore. Choose the radio button marked Create a Restore Point on the first screen then click Next. Give the Restore Point a name and then click Create. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go Start > Run and type: "Cleanmgr" (without the quotes). Click Ok > More Options tab > Clean Up in the System Restore section to remove all previous restore points except the newly created one.

Also, go Start > Control Panel and double-click Add or Remove Programs. Post back and report any Java entries that you have.

These two are out of date.

J2SE Runtime Environment 5.0 Update 6
Java™ 6 Update 7

You should remove them and get the latest from here:

http://www.java.com/en/download/index.jsp

These two are for Java development.

Java DB 10.3.1.4
Java™ SE Development Kit 6 Update 7

If you don't develop your own Java applications you can remove them also.
