Norton 2010 detects Java as Trojan Horse?

Question

Norton 2010 detected some Java files as Trojan Horses, is this just Norton messing up? I have Java and JDK (another Java program)

Answer 1

I agree with Keith M.



Plus you should also delete your Java cache (temporary files), Java virus can hide in there.



That is easy to do. Simply delete your Java Cache by following the directions below:



Here are the instructions on how to manually remove these malicious applets from the JRE cache directory:



1. From the Start button (or orb), > Control Panel

2. In the Control Panel, open the "Java"

3. Select the General Tab

4. Click the Settings button inside the Temporary Internet Files box, then click the Delete files button then click OK twice. This will clear your JRE cache directory.



BTW, Norton has an extremly SMALL amount of false-positive detections

Answer 3

If you need to know for sure, go to Jotti's free online virus scan

http://virusscan.jotti.org/en



and up load the files from your hd and let Jotti run them past 20 AV vendors. If they come back clean, report this to Norton and get rid of Norton. There is absolutely no excuse at all for an AV to give a false positive on Java.



You should also report the false positive to Sun Microsystems (they developed Java) so they can go after Norton for doing something like this. Disabling Java would break a LOT of things.

Answer 4

It is common for older versions of Java to become corrupted. You should have version 6 update 20.

I would uninstall all older versions of Java and reinstall Java latest version.

Edit - I have Norton 2010 on 3 machines and have never got a false positive yet. I also have Java installed and have no problems. If you do have an older version of Java I would trust the Antivirus on it.

Maybe you should submit the files ?

Answer 5

Norton is terrible and gives mass amounts of false-positives. I am sure that it is not a virus.

Answer 6

if it is the comcast (free version) just uninstall it completely, Google:Norton Comcast-click the 1st result and reinstall it.
