Solved PC is infected with NeixTCoup files, how to remove please.

PC seems clean, try to reinstall your Firefox.

 

[StanTheMan]

I reinstalled Firefox but it took a long time to download. Firefox is working, slowly. Still got Neixtcoup files when I run %temp% and the same neixtcoup file in the folder mozilla-temp-files. These neixtcoup files don't show when I use Internet Explorer. I'll attach a screenshot of the temp files.

 

[TwinHeadedEagle]

Can you manually delete these files?

 

[StanTheMan]

I can only manually delete them when Firefox is closed, otherwise it tells me it's unable to delete because the file is being used by Firefox. If I delete them with Firefox closed, then start Firefox and watch what happens in the temp folder the Neixtcoup files appear a few seconds after the browser opens. When I close Firefox, a second later those files disappear from the temp folder.

Ok, done.

PC seems clean. Can you use Firefox normally? Disregard these files and cache

 

[StanTheMan]

Firefox is working ok, thanks. The Neixtcoup files are still there and I suppose if I didn't check the temp folder I wouldn't know about it, it's just the thought that some unknown entity might by spying on my every browse and something somewhere keeps creating/modifying files on my laptop and seem to be impossible to remove. I could use Internet Explorer from now on but I'm not certain there's not something still lurking that's going to create more files there. Thanks alot for your help TwinHeadedEagle, really appreciate it.
