I dont have any AV, this lap. is too slow and old, if i install one of these and it starts scanning and watching in background, it will take years to compile each time.

I have divided the HDD to 2, part. C: has 37GB (14.3GB free) and part. E: 37GB (30.2GB free).
Sometimes reinstalling Delphi helps me.

But i will try to find out what it is later, have to do backups first.
