Lately, my computer has been not able to succesfully load files (as posted in my previous thread). I have not been able to find a solution other than just reinstalling the programs everytime they fail to work (which is about once every 2-3 days).
I have a theory that this is caused by a type of worm that keeps deleting my files. Only the same files keep disappearing, and I have no solution to this. I ran Avast few times, but no worm was detected. Any suggestions or advice would be highly appreciated.

Here is my HiJack log, just in case there is an error here.
