Very simply put, I think there MAY be a Trojan virus somewhere on my computer... it keeps popping up on my laptop. However, my Windows OneCare says it "deletes" it every time it comes. AVG doesn't detect any problems. But it keeps coming back. Help?

Also, is it possible for someone to help me clean my computer? For example, deleting my history, cookies, and things. I am afraid I will delete something important, and I have a bad tendency of letting all the bad stuff pile up for a really long time, so I was hoping for someone to help me stop it before it's too late.

Thank you!

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Also, just a sidenote... when I restarted my computer after I sent in the log file, it was slower than usual and the screen was all black for about 5-10 seconds before my computer started up.

Not sure if that regularly happens when after installing the Malware thing, but just so you know.

It's running well. No pop-ups, nothing's running abnormally slowly... Was that all? It was so.. quick and painless! :thumbsup:

Thank you for all the help. I appreciate it very much--I absolutely love the service I get on this website. Always the best. Thanks once again!

Oh, sorry, one more thing--is there any (free) antivirus software you recommend I download and use? (Currently, I use AVG Free.)

And is it safe to run those programs you had me install on my own? Or should I remove those from my hard drive?

I currently use Comodo Anti-Virus and Firewall. However, I wouldn't say that it is better than AVG. Preventing infection is not just about having a good anti-virus, your internet surfing habits play a big part.

Have a read of this: http://www.bleepingcomputer.com/forums/t/44675/how-did-i-get-infected/

Malwarebytes and SUPERAntiSpyware are both good applications and it certainly wouldn't hurt to run a scan with them from time to time.

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.

Sorry for the delay, but here are the Java apps:

Java™ 6 Update 13
Java™ SE Runtime Environment 6

That's all I think I have.

Also, I wasn't able to clean-up, because when i typed in "Cleanmgr," it asked me if I wanted to clean "My Files" or "Files from all users on this computer." I wasn't quite sure what to do, so I didn't do anything.

When I clicked "My Files," by the way, it only allowed me to choose which drives to clean up. It said nothing about system restore.

Those Java are out of date. You should remove them and get the latest from here:

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

Those System Restore instructions I posted are for XP. See here for Vista details:

http://www.bleepingcomputer.com/tutorials/windows-vista-system-restore-guide/

If you disable and then enable System Restore it will delete all the old restore points.
