    Found strange AppData\Local\Temp\ file


    I'm no longer software knowledgeable but have screen freezes and black screen flashes. Gave up asking my virus support. Yesterday I cleaned my computer using eraser and first files in AppData\Local\Temp\ it took 7 minutes before a strange file was deleted. No joke it showed "Zelensky ink.dll".I should have printed screen but didn't think until afterwards.I don't click on email attachments but I do research pretty heavily including other countries.Thank you!

    :)

    Excess Files? in ... \AppData\Local\Temp

    In my directory c:\...\AppData\Local\Temp, is there any need to keep the files there. My C drive is a small SSD so anything I can get rid of will help a lot.

    High capacity and fast fill of AppData\Local\Temp\jnjl32fl folder

    Hi,

    Recently i wound out that "USER\AppData\Local\Temp\jnjl32fl" folder get big pretty fast, and can reach 1GB data after 2 days.

    The folder contain Temp data of different microsoft application, especially, but not only, visual studio data.

    Please note that as I do installed VS, but i didn't used it in past week.

    Partial report show in the bottom.

    Is it a normal behavior? can it be some malware using those location?

    Please advice.

    Found strange AppData\Local\Temp\ file

    AppData/Local/Temp folder has deleted a file

    Stupidly I have been working on a temporary CAD file in AppData/Local/Temp folder, not sure how it happened (power cut maybe) but it came up as the top file on my list of recent files and I just opened it worked on it a few days ago and saved it. Actually
    I must have done this several days in a row. Scroll forward to today and it still comes up on my file list but doesn't seem to actually exist anymore. I have tried a file search with no luck. Several days work lost it seems. Does this file still exist somewhere?
    Any ideas?

    Thanks

    Will
