I have been having some problems with my Java applications. I came across a strange file at userName\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\host.
The file is called 6e44b93d-54c80a94.hst and has one line of text:
I have no idea why this is in what seems to be a Java cache.
I have been writing a Java game for a few years now and all of a sudden I have been getting huge blocks over the top of the games screens, its probably unrelated to the file. I dont have any identifiable malware or viruses on my machine and I'm trying to trace what could cause this.
The code runs fine on other machines and only this pc seems to be affected. It may be something to do with dual processors, but the code has run with no problems for years, so I am doubtful.
I really cant understand why I would have a host file in my Java cache leading to the same company you mention in your post....

The problem was resolved by updating my nvidia graphics card. It was strange that the program had worked for years with no problems. The driver file may have been corrupted but it was strange how it only affected some Java programs.

Make sure that your Java is up to date also.

Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older version Java components and update:
  • Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  • Scroll down to where it says "Java Runtime Environment (JRE) 6 Update 11".
  • Click the "Download" button to the right.
  • Select your Platform: "Windows".
  • Select your Language: "Multi-language".
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • Click Continue and the page will refresh.
  • Click on the link to download Windows Offline Installation and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Settings > Control Panel, double-click on Add/Remove Programs and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button and follow the onscreen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java versions.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-6u11-windows-i586-p.exe to install the newest version.
