Keychain taking up all disk-space

[hatirb]

Please help!
My disk is full. Everytime I delete somthing, it takes a day, and the disk is full again.
I have a second hand macbook air from 2010.
I ran omnidisksweeper, which tells me that my keychain file is taking up 192GB(!) I tried deleting it with this program, but it doesn't work!
Could it be a virus? I ran F-secure, and it didn't find anything.

Help is appreciated.

no wonder you are having problems.

You can see what is in your keychain buy using Keychain Access, this will show you whats putting stuff in it.

but I suspect its a failing harddrive, ensure you have a good backup.

Apple recommends that you operate with at least 25% free hard disk space. That's because it does all sorts of things with that space. On a MacBook Air, maintaining free space is always a challenge.

I'm not familiar with Omnidisksweeper, but when it reports a file with size 192GB on a MacBook Air, you know that whatever your problem is, it's serious! Is your drive 80 or 120GB? I suspect Kaveman's on the right track, something is very wrong with your hard drive.

Make a thorough backup of your files. Get a brand new good quality external drive, and run a complete Time Machine backup. Then take it to a qualified Mac specialist and get them to investigate.
