Recently had Avast ( free version ) report various files with Win32:Trojan-gen. of the types {UPX!} {Other} and {VB}.

However, unable to find any virus cleaning references to those mentioned above on AVAST site or any other virus definition database.

Ran Home Scan from Trend @ www.antivirus.com and it found several Java infections. java.bytever.A-1 / A / B / C / D / 3 and Troj_RG.A. The latter is detailed also on the symantec website database as part of malware. Files found in C:\Documents and Settings[username].jpicache\1.0

The cache can be manually emptied (cleaned) by Start | Settings | Control panel | Java-plug-in | Cache | Clear.

  1. Why doesn’t Avast check for these java problems ?
  2. Is there an AVAST update so scans report virus / malware names that match to those contained in other databases ? ???
