DAP is an download manager. It's not like the P2P programs and it is safer because the user can scan the file downloaded with the Anti-Virus he usualy uses

Great Download Manager

If you do't need it get rid of it because it can use a lot of CPU when starting up
older version was very good. newer versions include adware in free version, still useful, but annoying. Considered paying for it, still looking for a free download accelerator that supports resumption of interrupted downloads. Will keep until I find a good alternative, or buy to remove ads.

Best practices for resolving dap issues

A clean and tidy computer is the key requirement for avoiding problems with dap. 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.

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.
