Accidental deletion of Filter Options

[SaxBlower]

I think that I might have accidentally deleted a "Filter" when viewing Vulnerability/Detailed Report. I fumbled with the mouse and the line detailing the vulnerability disappeared
Does "Delete Filter" refer to a Firewall filter and if so, is there a way to re-set filters.

I was trying to find out if the vulnerability was to do with Exploit:Java/CVE-2012-0507.D!ldr that Microsoft Safety Scanner found but did not delete.
KIS did not find or delete this

The microsoft site states: Exploit:Java/CVE-2012-0507.D!ldr is a detection for an obfuscated malicious Java class component stored within a Java Archive (.JAR), that uses its elevated privileges to download and execute other malware.
