I am the user of Avast 4 Home Edition antivirus software nearly for 6 months and for the safety reason, I am usually perform the standard virus scan for all my local non-removable disks with archive files and the result is no files was infected.
However, later for the more safety reason, I perform the Thorough scan for all my local non-removable disks with archive files yesterday (i.e. This is the first time to perform the thorough scan) but the result is 7 files were infected by virus of Other: Malware-gen and I take the recommendation of Avast and moved all these 7 infected files to virus chest immediately. The information in virus chest are as follows:
7 files were infected by virus of Other: Malware-gen
Name: BnnnnBaa.class
Bnnnnn.class
Den.class
Din.class
Dnnny.class
Dun.class
VaannnaaBaa.class
Original Location:
C:\Users\Karen\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\32\7836d960-79dcd28e
In my Log viewer, there also had the warning section, and the description is Sign of "Other: Malware-gen" has been found in
“C:\Users\Karen\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\32\7836d960-79dcd28e\BnnnnBaa.class” file.

My virus database version is 081221-0 and Avast version is 4.8.1296 and after the infected files were moved to chest, I perform the standard virus scan again and the result is no files was infected.
Today, my virus database version is updated to 081222-0, and I perform the standard virus scan for all my local non-removable disks with archive files again and the result is no files was infected.
Am I doing the right action (i.e. move the infected files to chest) when the virus of Other: Malware-gen is found…and why the virus of Other: Malware-gen cannot be detected in standard scan but can be detected in Thorough scan.
Is my notebook safe now and am I need to perform thorough scan everytimes? And do I
need to clean or remove the virus of Other: Malware-gen in the virus chest or just leave it in the chest is OK.
Thanks for kindly attention....
