This is indeed a threat, though it has more to do with a vulnerability in an old version of Java rather than anything "too" serious. It is not something that should be too hard to fix. The reason Kaspersky only identified the threat once is because that time you ran a Full Scan, whereas the other two times you only ran a Quick Scan. As this is not a serious threat (and due to various other factors), Kaspersky only shows these when you run a Full Scan.
First of all, lets update your Java to the latest version:
To update Java
Run JavaRa.exe, pick the language of your choice and click Select. Then click Remove Older Versions.
Accept any prompts.
Open JavaRa.exe again and select Search For Updates.
Select Update Using Sun Java's Website then click Search and click on the Open Webpage button. Download and install the latest Java Runtime Environment (JRE) version for your computer.
Please download JavaRa
to your desktop and unzip it to its own folder
Now, lets run a scan with Malwarebytes Anti-Malware, just to be sure there are no infections.
(Note: if you already have the program installed, just follow the directions. No need to re-download or re-install!)
Double Click mbam-setup.exe to install the application.
(Note: if you already have the program installed, open Malwarebytes from the Start Menu or Desktop shortcut, click the Update tab, and click Check for Updates, before doing the scan as instructed below!)
Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes Anti-Malware, then click Finish.
If an update is found, it will download and install the latest version.
Once the program has loaded, select "Perform Full Scan", then click Scan.
The scan may take some time to finish,so please be patient.
When the scan is complete, click OK, then Show Results to view the results.
Make sure that everything is checked, and click Remove Selected.
When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. If you are prompted to restart, please allow it to restart your computer. Failure to do this, will cause the infection to still be active on the computer.
Please save the log to a location you will remember.
The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
The log can also be found at C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt
Copy and paste the entire report in your next reply.
