Software > Computer viruses and spyware
had disk memory vanishing fast and varying up and down
bnorth:
Dear List,
I have a 2.5 year old laptop running windows 10 with office 365.
It only had a 118Gb hard disk but the amount of free Gb on the hard disk seems erratic and to be draining fast.
Also trying to inspect the whole laptop with "This PC" and a file explorer seems to snarl up with a "working on it" message forever..
But when I open disc manager I now have 2.16 Gb hard disk/ C:, It has varied between 256 Mb and 10Gb over the last day
But I've not been saving big files or indeed doing much with it - do I have some malware ?
Here's the zinger !! yesterday while I was out its c: memory dropped to 333Mb causing much panic. I moved some stuff off C: (not much) and ran avast anti virus and rebooted and not sure what worked but suddenly I had 10GB
I have malwarebytes as well as avast
its a mystery and a worry to me
many thanks for any advice

Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.
1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
2. The fixes are specific to your problem and should only be used for this issue on this machine.
3. If you don't know or understand something, please don't hesitate to ask.
4. Please DO NOT run any other tools or scans while I am helping you.
5. It is important that you reply to this thread. Do not start a new topic.
6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
7. Absence of symptoms does not mean that everything is clear.
If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.

many thanks for your time and help, SuperDave, I've run the 3 processes you mentionned
my spologies for the delay replying.
just for info I wasn't sure or not if it was a malware issue but when I posted on the "other" board it was suggested I report here. Maybe free hard disk space does rapidly vanish anyway due to temporary files ?? even without malware ??
--- my adware log seems clear (and I didn't quarantine the acer jumpstart thing)

---the windows defender scanned seems to run without issue. when my laptop rebooted the free space on my hard disk had increased from under 1 GB to over 9 GB. I think rebooting always restores some space (but it soon reduces, maybe thats normal or the estimates of free space aren't accurate

Download Security Check by screen317 from the following link and save it to your desktop.
Security Check
* Double-click Security Check.exe
* Follow the on-screen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt
* Post the contents of that document in your next reply.
Note: If a security program requests permission from dig.exe to access the Internet, allow it to do so.

thanks, SuperDave,
I downloaded that tool and double clicked but got a "file or directory is corrupted and unreadable" error
I was looking at this site https://www.makeuseof.com/windows-10-fix-the-file-or-directory-is-corrupted-and-unreadable-error/ and tried restarting and moving the file to on avail - maybe I need to run the diagnostic tool ?
other files in that directory are available so its not the directory as a whole thats corrupted
sorry to take your time
