    My Local Disc C is at 90% full all of a sudden: I only have about 9GB free from a total of about 200GB. I have two other discs - D for random things like movies, music, pictures etc. and E for games and programs, both were given 400GB and are almost free as I don't store much on my computer. I install nor store anything on C other than what Windows puts there so my disc was at 20GB usage at most before this happened.
    I looked through the properties of all my folders in C and they are nowhere near this amount of data so where is this coming from and what can I do?

    Additional info:
    1. I tried to install a pirated copy of Adobe Illustrator 6 days ago (re-installed many times, couldn't crack so eventually I gave up and removed the whole thing - I only needed it to view a single file anyways), I think this happened after that but am not sure as I only noticed it yesterday - could that have bugged my system somehow?
    2. I tried restoring my system to a previous state but it keeps failing to do so.
    3. I run a Windows 7 Ultimate

    Any help would be greatly appreciated...

    Do the following in that computer.


    Download and save the TSG System Information Utility (SysInfo.exe) to the desktop.

    After it's been downloaded and saved, double-click it to run it.

    Information about your computer will appear.

    Return here to your thread, then copy-and-paste the ENTIRE text here.

    After your explanation I would run a full malware scan using something like Avast Antivirus and then Malwarebytes as well as the above.

    Hi nafora and welcome to the forum!

    I agree, running a malware scan would be helpful. Also, you can check how much space your system restore points are taking up. They can pile up and eat up a lot of space. Be sure to check your Windows page file. It could also be due to a program making a backup of itself, however, after the description, I too suspect malware as the most likely suspect. You could run a cleaning software, I cannot recommend any, however, there are plenty online and other users would surely help ;).
    After you have done that I strongly recommend considering a back up solution for the important data. You could also run a brand specific diagnostics test on your hard drive just to be on the safe side. Post the SMART here after the extended test (if anything is unclear ;) )

    P.S. Tell me if you would like me to provide more detailed instructions on how to go about the steps above. Be sure to check for malware before them, however. Also could you share the brand and model of the drive?

    Keep us posted,
