As part of its installation, Java will add jusched.exe
to startup when Windows loads. This process is related to Java Update
, a feature which connects to java.com at a scheduled time and checks to see if there is an update available. It is not necessarily to load at startup and can be safely disabled with a Startup Manager or in the Java Control Panel
to save resources and improve performance.
Since there are Fake Sun MicroSystems Java domains
which can lead to infection, I prefer to disable automatic updates
and manually check for them which helps to avoid a bogus update prompt.
When I then ran a virus scan with AVG 2011 it picked up 2 applets as malicious and I deleted them
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:
Please follow these instructions: How to remove Google Redirects or the TDSS, TDL3, Alureon rootkit using TDSSKiller
-- For any files detected as 'Suspicious' (except those identified as Forged to be cured after reboot) get a second opinion by submitting to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.Step 9
- Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
Vista/Windows 7 users right-click and select Run As Administrator.
- When the program opens, click the Start Scan button.
- If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
- Ensure Cure is selected, then click Continue > Reboot now to finish the cleaning process. <- Important!!
Note: If 'Suspicious' objects are detected, you will be given the option to Skip or Quarantine. Skip will be the default selection.
- A log file named TDSSKiller_version_date_time_log.txt will be created and saved to the root directory (usually Local Disk C:).
- Copy and paste the contents of that file in your next reply.
recommends that you scan your computer using Malwarebytes Anti-Malware
to remove any traces that may still be present. If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it 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 Malwarebytes from removing all the malware. After performing that step, please post the complete results of your scan for review.
