java virus?

W

W????n

AVG tells me that these three are viruses:

getaccess.class
insecuredclassloader.class
installer.class

They are located in a hidden folder in app
data\sun\java\deployment\cache\javap:\v1.0\classload.jar41\****viruses****

When I click for more info it tells me that there are windows updates
available to prevent the abuse of this java weakness, however, I have all
updates and AVG still lists it as viruses.

What is the concensus on this situation if anyone knows?

Delete the classload.jar41 file or directory.

Also..

start --> settings --> control panel --> java

Clear the Java cache.

Then perform the following...

1) Download the following two items...

Trend Sysclean Package
http://www.trendmicro.com/download/dcs.asp

Latest Trend signature files.
http://www.trendmicro.com/download/pattern.asp

Create a directory.
On drive "C:\"
(e.g., "c:\New Folder")
or the desktop
(e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

Download SYSCLEAN.COM and place it in that directory.
Download the signature files (pattern files) by obtaining the ZIP file.
For example; lpt307.zip

Extract the contents of the ZIP file and place the contents in the same directory as
SYSCLEAN.COM.

2) If you are using WinME or WinXP, disable System Restore
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
3) Reboot your PC into Safe Mode
4) Using the Trend Sysclean utility, perform a Full Scan of your platform and
clean/delete any infectors found
5) Restart your PC and perform a "final" Full Scan of your platform
6) If you are using WinME or WinXP, Re-enable System Restore and re-apply any
System Restore preferences, (e.g. HD space to use suggested 400 ~ 600MB),
7) Reboot your PC.
8) If you are using WinME or WinXP, create a new Restore point
9) Please report back your results

David,

The results of the scan, which took a long time, were negative.

Seems to be a very thorough scanner, however.

What is with the access denied areas that did not get scanned?

Thanks again.

The results are as follows:

These are actively used files whose file handles are held open by the OS and thus they can't
be scanned.

They are; system files, Registry and LOG files. This is to be construed as normal
behaviour.

AV will detect as malware even things you are immune to. This detection is probably of exploit
code and you may have already patched for the vulnerability it exploits. The AV won't know
(nor will it care) what steps you have taken to increase your security.
