Hi, I just gave up on Avast, since it failed to detect some crap on my computer. I have not installed the trial version of NOD32, and i appreciate its light resource usage. However, one of the surprises that Avast left me was this: "C:\Documents and Settings\Administrator\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar\javainstaller.jar-5aa0b436-3e745a10.zip »ZIP »javainstaller/InstallerApplet.class - Java/TrojanDownloader.OpenStream.W trojan" When NOD32 finds this, it says it can be deleted, but only gives me the option of "Leave". It also has problems accessing some system files since they are in use. I have tried looking for a boot time scan option that could run before windows starts, as was present in Avast, but i havent been able to find one. Is it possible to schedule such a boot time scan, and if not, what should one do about files that NOD32 cant delete/clean? Thanks for helping out.
