Vmain.class - Keylogger?


Recommended Posts

Hi, first time looking for help so I apologise if I do something wrong.

Last night I was using the internet and noticed a windows notice saying both my malware protection (Trend micro) and my firewall were both switched off. No one had turned it off. After switching both back on I updated and then turned the internet off to run a scan.

On competition it found 4 instances of vmain.class at C:\Users\*****\Appdata\Local\Low\Sun\Java\Development\Cache\6.0\.

It quarantined these, and I have since deleted the infected files, but am still worried that something may be wrong as my computer still a little odd (plus I am easily paranoid :)) I have run malware bytes and it has come up clean.

Any help is greatly appreciated, and if I need to add more information please let me know. Thank you.

Please perform the following scan:

  • Download DDS by sUBs from one of the following links. Save it to your desktop.

    [*]Double click on the DDS icon, allow it to run.

    [*]A small box will open, with an explanation about the tool.

    [*]When done, DDS will open two (2) logs

    1. DDS.txt

    2. Attach.txt

    [*] Save both reports to your desktop.

    [*] The instructions here ask you to attach the Attach.txt.

    [*]Instead of attaching, please copy/past both logs into your Thread

    [*]Close the program window, and delete the program from your desktop.

Please note: You may have to disable any script protection running if the scan fails to run.

After downloading the tool, disconnect from the internet and disable all antivirus protection.

Hey Thank you so much for your reply!

Just a question, is it safe to have my computer and/or interenet switched on at the moment? Should I switch them off when not looking at this forum until I get the all clear?

Here are the logs:

Here are some additional links for you to check out to help you with your computer security.

Browsers

Just because your computer came loaded with Internet Explorer doesn't mean that you have to use it, there are other free alternatives, FIREFOX and OPERA, both are free to use and are more secure than IE.

If you are using firefox you can stay more secure by adding NoScript and WOT (Web Of Trust)

NoScript stops Java scripts from starting on a web page unless you give permission for them, and WOT (Web Of Trust) has a comprehensive list of ratings for different websites allowing you to easily see if a website that you are about to go to has a bad reputation; in fact it will warn you to check if you are sure that you want to continue to a bad website.

  • Make your Internet Explorer more secure - This can be done by following these simple instructions:
  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
  • Change the Download signed ActiveX controls to Prompt
  • Change the Download unsigned ActiveX controls to Disable
  • Change the Initialize and script ActiveX controls not marked as safe to Disable
  • Change the Installation of desktop items to Prompt
  • Change the Launching programs and files in an IFRAME to Prompt
  • Change the Navigate sub-frames across different domains to Prompt
  • When all these settings have been made, click on the OK button
  • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.

Additional Security Measures

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

SpywareBlaster- SpywareBlaster will add a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

A tutorial for Spywareblaster can be found here.
