1. You still have one HijackThis log entry left over from the infection. Run HJT again and have it fix:
O2 - BHO: (no name) - {58F07DD3-924D-4141-BC74-299F523A95F1} - (no file)

2. I can't tell you exactly what happened in terms of the lost space at this point, but I can you that it isn't a normal side effect of infections (or removing them). There could be a few different reasons for the problem, though; let's see if we can narrow it down:

A) Look for "bloated" files or folders:

- Open Windows Explorer, and in the Folder Options->View settings under the Tools menu, select "show hidden files and folders", and uncheck "Hide protected operating system files" and "Hide extentions for known file types".

- Click on the Search button, and in the resulting "Search Companion" pane:

* Leave the "All or part of filename" and "word or phrase in file" boxes blank.

* Click on "When was it modified" and specify a date range that would most closely reflect the time during which the loss of disk space occured.

* Click on "What size is it? and select "Don't remember".

* Click on "More advanced options", select "all files and folders" for the type of file, and put a check mark next to the search options for system, hidden, and subfolders.

Let the search run, and when it completes, look for any items whose size looks abnormally large. Give us the names of any such items you find.

B) Mis-reported disk space can be caused by corruption of the filesystem information that Windows maintains for drive (in the Master File Table, for example). In other words, the space you lost may not really be occupied by data, but Windows thinks that it is.

Running the chkdsk utility in read-only mode will check your disk for such inconsistencies; more info on this can be found in this Microsoft Knowledge Base article.


ei thanks alot i followed your advise and saw a folder name _avast4_ containg chunks of files ranging from 0kb to 425 mb of size about a total of 26 gb in all and i just deleted it and there is no problem.. thanks for helping me find those useless files.. you guys are really dependable


Glad we could help :)

I don't use Avast!, but the folder you describe sounds like it could be Avast!'s virus quarantine folder or something similar; that would account for its growth.
