C Drive Space increases and decreases
- 
 The laptop with Windows 7 Enterprise 32 bit has the issue that the C drive space automatically increases and decreases when it is connected in network. 
 So I have disconnected the laptop from the network.
 The machine is encrypted with McAfee Safe boot.
 The C drive free space 500 MB yesterday evening.
 When I checked today it reduced to 150 MB and after 1 hour usage the free space is 250 MB only.
 What can I do for this issue?

Execute the program as Administrator.

 Defregment the Drive once. Also check antivirus log folder, normally this will be the folder which consumes space.
