Hey guys, I'm new here! I was just wondering if I had a virus or not? If I remember correctly, I received it around the last part of June, and Microsoft Security Essentials picked it up and cleaned it. I ran MalwareBytes as well after words, and I couldn't find any problems. This past weekend, I opened up Microsoft Security Essentials and looked at the history, and saw
TrojanDownloader:Java/OpenConnection.EE
Exploit:Java/CVE-2009-3867.BW
Exploit:Java/CVE-2008-5353.FJ

All showed a Severe alert level. The date it was found was 7/24/2010 at 6:44 AM and it looked like all were removed. I did another full scan with MalwareBytes, and couldn't find anything. I ran one more scan with MSE and did not find anything either. I haven't really noticed any difference in my computer...but I would like some feedback if I need to do anything else.

Thanks!
Shawn

Hello Shawn. Is this XP or another system?
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).


Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.
