Are you using Windows XP?
Can you schedule a boot-time scanning?
Start avast! > Right click the skin > Schedule a boot-time scanning
Select for scanning archives.
Boot. 

When prompted for the infected file, try to repair or delete the infected file (specially if it is on a temporary folder or system restore one). Oh, by the way, maybe it will be better disable System restore on Windows XP: http://support.microsoft.com/default.aspx?scid=kb;%5BLN%5D;310405

Java exploits may arrive in the Java cache when visiting a site which pushes malware.

Anti-virus programs detect such malicious applets (Java exploits) in the following directory:

C:\Documents and Settings\<username>\Application Data\Sun\Java\Deployment\cache\javapi\v1. 0\jar\

These malicious applets are designed to exploit vulnerabilities in the Microsoft VM (Microsoft Security Bulletin MS03-011).

If you are using the Sun JVM as your default virtual machine, these malicious applets cannot cause any harm to your computer.

Check the file location: if it is in Java\Deployment\cache\javapi\v1. 0\jar\, then this is what happened to you.

Older versions of Sun Java were also vulnerable to exploits so it's vital to update to the latest version AND TO UNINSTALL OLDER VERSIONS.
