Features

According to SpeedBit, Download Accelerator Plus has approximately 150 million users worldwide. A free version and a premium version exist. It has a number of features like scheduled download and auto Internet disconnection and/or shutting down of computer upon download completion. DAP also provides auto antivirus scanning of downloaded contents by integrating with the antivirus software (such as Norton AntiVirus, McAfee VirusScan or AVG Anti-Virus) present in the OS, though this feature may not work properly with some antivirus applications. DAP integrates very well with Internet Explorer, Mozilla Firefox, Netscape, and Opera. It pops up a small message box by the notification area with "Open/Play" commands upon completion of download. It also has a password manager for websites. There is a commercial version, which is ad-free, and has some extra functions, such as "Always Resume" and DAP drive (a virtual download storage). DAP 8.5 has a file security check, provided by ZoneAlarm, which will alert the user that he/she is about to download or run a potentially dangerous file.

Limitations and issues

• Sometimes DAP will not uninstall. This problem is known to SpeedBit.^{[citation needed]} A known cause is uninstalling an older version of DAP and then installing a newer version of DAP without rebooting, which causes the removal files from the newer version by accident during the next reboot, since they are given the same name and placed in the same location as the older files that are scheduled to be deleted. The advertisements that appear in the faulty uninstall, in Windows’ Add or Remove Programs, gives off the impression the uninstall was purposely removed and replaced with ads^[1]. The fix is to reinstall the newer version of DAP and then uninstall it, rebooting before and after each install and uninstall.
• The Windows 98 version seems to have exorbitantly large memory leaks.^{[citation needed]} The result being that in Windows 98, DAP is more resource intensive, forcing one to close most other running applications even on a PC with well over 256MB of RAM.
• Some older versions creates dynamically expanding temporary files during download, which makes the completed file very fragmented. This error is fixed in current versions.
