Bittorrent client, not dangerous but uses an excessive amount of CPU as it is java based.
it will not open for me and it always says java has a error and i do not know why
since i installed it, my PC has slowed right down and takes forever to shutdown and startup. uninstall does not work.i am unable to delete the program and unable to change owner access rights... it sucks.
its a p2p software,hey it was working fine for days,but my avg detected a virus , a trojan virus, i will advice first to download a anti-virus
Runs for the Vuze program. Sometimes runs on its own.
my best downloader.
Azureus BitTyrant is indeed very fast when it comes to downloading, surely it slows my computer but I really prefer a faster download. For me Azureus BitTyrant is A1 compared to others
It runs when you've got Vuze open

Best practices for resolving Azureus issues

A clean and tidy computer is the key requirement for avoiding problems with Azureus. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Azureus.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
