Malware-gen [Trj] found

Today I have run a start-up scan with Avast Free.
Malware-gen [Trj] was found at C:\Users\Herman\AppData\LocalLow\Sun\Java\Deployment\SystemCache\6.0\23\3db38257-7979856c
What to do, which option #?
Advice and help is appreciated, thanks in advance.

MBAM quick scan did not detect anything.

Best regards, Herman

Allow avast to move it to the chest.

Clear your JAVA cache, Update JAVA. According to your path you have JAVA 6 update 23 and that is an old version, older versions are more likely to have vulnerabilities (which have been fixed in updates) exploited.

We are on JAVA 7 update 5 (or 6) now.

Someone else also posted a similar question. I have the same problem, too. Mine is 3db38257-56998e71

I would follow the same advice, given that this is the JAVA cache, that is essentially a temporary location and ensure that you have the latest version of JAVA.

Thanks guys for your replies.
I was unable to find Java on my computer.
Secunia PSI scan: all programs are up-to-date.
Scan by Avast Free: file > chest.
The I have downloaded the newest version of Java (version 7 update 7).
Will run another start up scan this afternoon.
Will report after scan.
Keep tuned.

You’re welcome.

JAVA isn’t that easy to find, the C:\Users\Herman\AppData\ folder may be hidden. However installing JAVA 7 ‘should’ remove earlier JAVA versions (but I never rely on that). Check the windows add remove programs/programs and features for any JAVA 6 entry.

Oh well, everything seems to be “clean” right now.
I wanna say thank you Richard for your great help and support. Thank you!

No problem, glad I could help.

It’s David though ;D

Thanks David for great support!
