This seems very serious.
I know of some malware that can stop your task manager/ run/ regedit.
but to delete all the updates and hjt.... this is beyond me.
Only thing i can suggest is that once you have hjt installed....... re name it before you try to run it.
Some malware programs can recognise HJT.
Try doing the following:
Go to the folder that Hjt is saved in,
Right click on Hijackthis.exe and select Rename
, rename it to 'anything you like
Double click on 'anything you like
(which is still Hijackthis.exe),Run another scan and see if it will produce a log.
(when i say..... 'anything you like'.... i mean any name you can think of... no matter how silly it sounds.
Chances are, the malware won't have thought of this name. lol
If it does produce a log..................
I suggest you post a HijackThis log for examination.

Once you have made the post, please, DO NOT make another post in the HJT forum, until it has been responded to by a member of the HJT Team. The first thing they look for, when looking for logs to reply to, is 0 replies. If you make another post, there will be 1 reply. The team member, glancing over the replies, might assume someone is already helping you out, and will not respond. So, just make your post, and let it sit there, until a team member responds. This way you will be taken care of, in the most timely manner.
