By deleting all the files and registry entires. But that’s done automatically by my NSIS Media Remover. See the Downloads page.

How did you remove it manually?

[...] December 9th, 2006 by kichik I just found another list of DLL files used by NSIS Media. The script used in their updated installers first removes the old DLL files. It renames them to temporary names and deletes all of their registry keys. Along with the previous list, I believe this makes a complete list of all DLL files used by NSIS Media. bsdeff32.dll java52e.dll krnsvr32.dll mkdesk32.dll mkdesk32.dll mscron32.dll msidext.dll msrvdrv.dll msscsi.dll mssvide.dll msxmlu.dll mtxcdru.dll netstrap42.dll nvrssid.dll odbcpc32.dll oleac32.dll olescope.dll uuiedes.dll windexserv.dll winsdev.dll winsdrv.dll wmbmd.dll wmddsb.dll wmdmb32.dll wmidext.dll wmproxt.dll wmsql32.dll wmudrv.dll ~fdgar.tmp ~fdgdr.tmp ~fdger.tmp ~fdgfr.tmp ~fdgir.tmp ~fdgor.tmp ~fdgpr.tmp ~fdgqr.tmp ~fdgrr.tmp ~fdgsr.tmp ~fdgtr.tmp ~fdgur.tmp ~fdgwr.tmp ~fdgyr.tmp ~isdat.tmp ~isddt.tmp ~isdet.tmp ~isdft.tmp ~isdit.tmp ~isdot.tmp ~isdpt.tmp ~isdqt.tmp ~isdrt.tmp ~isdst.tmp ~isdtt.tmp ~isdut.tmp ~isdwt.tmp ~isdyt.tmp [...]

I had to remove it manually. It wasn’t too hard due my prior research and all of the online reports. Anti-malware programs are slowly picking up more and more parts of it, but when I had to remove it, those I use picked up nothing.

Ha Ha.
You think people don’t want advertisement on their computer?! of course they do people need useless information any where they can get it!

If you had no useless information to get rid of
than you couldn’t decide what is useful.

Btw

Did you have to remove everything NSIS Media installed manually or do anti malware program’s pick it up automatically?
