You may want to create a standard user with limited rights which you use for "Internet" only tasks.

Details:

This JAVA malware is found in malicious Web sites as part of a Web page applet . It comes in the form of a compiled Java class, and may be called from an HTML page .

It exploits the ByteVerifier vulnerability in unpatched versions of Microsoft (MS) Java Virtual Machine, which could allow a file to be downloaded and executed without a user’s knowledge .

This variant of the JAVA_BYTEVER malware arrives as the following files:


counter . class
matrix . class
The file, COUNTER . CLASS, which contains the specially crafted code of the exploit, uses the classes defined in MATRIX . CLASS to execute its payload .

It connects to the following Web site where it downloads a file and saves it as LOADNEW . EXE:


. biz/dl/loadadv479 . exe" target="_blank">ifram<BLOCKED>lars . biz
It then executes the file .

This malware takes advantage of the ByteCode verifier exploit that allows Java applets to execute malicious code .

More information on this exploit is available in the following Web page:

342079 2005-04-06 04:55:00 Sounds like an updated java engine is required. Get it version 1.50.2 from java.sun.com KiwiTT_NZ (233)
342080 2005-04-06 05:05:00 Thanks guys...

Godfather... what you have posted I tkae it that it is fairly safe to delete thie file form the AVG quatentine area?

I am currently on dialup and have ordered broadband which should hopefully be installed soon, I'm also looking at getting a dvd writer early next week for backup purposes before I install sp2.

Once I have broadband I will update these security patchs too... ( as you can imagine dialup is not fun to download large files)

Thanks.

I think this is what u need
