OK today my computer, for the second time in it's life, detected a virus. according to Norton, it's Trojan Horse Virus (last time it was Downloader.Trojan).
6 files: Dummy.class, RunString.class, Parser.class inside a zipfile, and 3 more files with same names inside another zipfile.
both zips were at:
D:\Documents and Settings\<user>\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar\<infected zipfile>.
same thing in the previous (first) time - infected zipfile at the same location.
1. why didn't Norton AntiVirus catch it when the file was loaded into the computer? (the virii were detected during a manual scan of the entire computer, not by a running detection service).
2. what's up with this Java getting infected?
i installed Sun Java a while ago (can't remember why), obviously these two infections happened after. what's up with that? is Sun Java more susceptible? never had a virus before (when apprently was using MS Java).
in IE -> Tools -> Internet Options -> Advanced, under Java (Sun)
i have Use Java 2 v1.4.2 for <applet>
checkmarked. under Microsoft VM
i have JIT compiler for virtual machine enabled
checked. as far as i understand both Sun and MS are active?
should i dispose of Sun Java? how exacly do i do this?
should i diable the Use Java 2 v1.4.2 for <applet>
in IE and then uninstall Java 2 Runtime Environment, SE v1.4.2
from the control panel)? anything else needs to be done to enable MS Java?
in the Tools -> ... under Microsoft VM
there are two more checkboxes marked Java console enabled
and Java logging enabled
. currently unchecked. should i check them?
any assistance welcome
