I have recently been having issues with my computer, mostly with online video. When i would stream video from the internet usually it would get so far and then completely freeze my computer (nothing would work including my mouse and keyboard). When it would freeze there would be this constant high pitch beep coming from the speakers until i would reset the computer. I noticed that when this happens my CPU usage was stuck on 100% (which i didn't think was normal). I recently installed Symantec anti virus and ran a scan. It found 8 virus'.

These were the results of the infections:

Trojan Horse-------Quarantined----------jar_cache2899286907122518078.tmp
Trojan Horse-------Quarantined----------txt/a/soundbl.class
Trojan Horse-------Quarantined----------txt/a/go.class
Trojan Horse-------Quarantined----------jar_cache1565059896812673234.tmp
Multiple Risks-----Quarantined----------jar_cache1284987407858076789.tmp
Trojan.Gen---------Quarantined----------dks/q/LoaderX.class
Downloader---------Cleaned by deletion--dks/q/DjewersA.class
Trojan.ByteVerify--Cleaned by deletion--dks/q/AdfsjlT.class


I am looking for help to see if anyone knows how to completely remove these trojan virus' without reformatting my hard drive. Let me know what you think.

Thanks

Hello,let's see if there is any malware left

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.

Yes this is Windows XP.

I still get some random popups every once in a while but so far i haven't had any pages redirected. When i scroll up/down on some webpages it is really choppy and is pushing my CPU to 100% the whole time it is on that particular website. This doesn't happen on all websites but on ones with high Java and graphics it seems like. This never happened until i started getting all the virus symptoms. My internet used to run really smooth. I just ran symantec antivirus again last night and it found 4 more virus'. One was a downloader and the other three were Trojans. It deleted three of them i believe but quarantined the other one.

Also, my video card is only about 4-5 months old and is a much better one than the old one i had.

hello ,then we need to run these and see the logs.

Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.



Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

If a file is in quarantine it cannot harm the PC.. You can delete them if you want .
Clean, Quarantine, or Delete?

Yeah i wasn't sure if it would make my computer go unstable if i deleted them. I used to the days where you supposed to load safemode when you delete any virus. I will give that a try and run another scan. I will post my results then.

It seems like there are Java files infected. Here is a location of one of them:

c:\Documents and Settings\Name\Application Data\Sun\Java\Deployment\cache\6.0\2\42aa7c82-6c63feb1

Filename:
________vload.class

There are 5 Java files infected. 3 of them were deleted by Symantec and 2 were quarantined (above one was quarantined)

The rest seem to be in a Temp folder:

c:\Documents and Settings\Name\Local Settings\Temp\jar_cache1284987407858076789.tmp
Filename:
dks/q/DjewersA.class

If i had to guess i would say that the reason why my CPU is running at 100% and my computer runs choppy on high Java sites is because these Java files are infected. What do you think?

Do you think if i delete these manually that my computer would screw up more?

I know i just posted a message but i just got a new issue. Adobe Acrobat Reader updater shows up in my system tray saying that updates are available. Normally if i don't want to update i can right click on it and exit the updater. With this one i don't have that option.

I ran it the first time and it got to 1% complete and then i go a blue screen error.

I just ran it again (2 days later) and the same thing happened (after the blue screen my computer automatically restarts).

It is coming up again but obviously i am not going to run it.

Hope this helps. Let me know what you think.

Let's check your JAVA and an explanation I'll quote from our quietmqn7.
What version of JAVA is running?
Go into Control Panel>Add Remove Programs. Be sure the 'Show Updates' box is checked. Go down the list and tell me what Java applications are installed and their version. (Highlight the program to see this).

EDIT: as with JAVA older versions of Adobe can be exploited and that is why Adobe issues the updates.

QUOTE:
When a browser runs an applet, the Java Runtime Environment (JRE) stores the downloaded files into its cache folder (C:\Documents and Settings\username\Application Data\Sun\Java\Deployment\cache) for quick execution later and better performance. Malicious applets are also stored in the Java cache directory and your anti-virus may detect them and provide alerts. For more specific information about Java exploits, please refer to Virus found in the Java cache directory.

Notification of these files as a threat does not always mean that a machine has been infected; it indicates that a program included the viral class file but this does not mean that it used the malicious functionality. As a precaution, I recommend clearing the entire cache to ensure everything is cleaned out:
