This new process recently appeared in my Ctrl-Alt-Del menu.

hosy77798.exe

Filepath and Registry:


C:\Program Files\Common Files\hosy77798.exe

HKEY_LOCAL_MACHINE > SOFTWARE > MICROSOFT > WINDOWS > CURRENTVERSION > RUN > hosy

I have no idea where this came from, and neither SpyBot nor AVG are giving me grief about it, but the sudden appearance of processes I don't recognize make me grumpy. Does anybody know if I should be concerned, and whether or not I can simply take out the registry file to prevent it initializing at start-up?

Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.

boopme looks like we are on the same page with this.

Both show the file as Infected/Malware, if I am reading this correctly. I suppose the next question is whether or not it is safe to simply delete the file and remove it from the Start-up registry, or if more steps are required. A quick Google search showed no applicable results... but maybe I'm not looking for the right things.

(And thanks for the quick replies on the initial question :D )

Windows XP SP2, by the way. I should have said that earlier.

Please download OTMoveIt2 by OldTimer and save to your Desktop.
  • Double-click on OTMoveIt2.exe to launch the program.
  • Copy the file(s)/folder(s) paths listed below - highlight everything in the quote box and press CTRL+C or right-click and choose Copy.

C:\Program Files\Common Files\hosy77798.exe

  • Return to OTMoveIt2, right-click in the open text box labeled "Paste List of Files/Folders to be Moved" (under the light blue bar) and choose Paste.
  • Click the red MoveIt! button.
  • The list will be processed and the results will be displayed in the right-hand pane.
  • Highlight everything in the Results window (under the green bar), press CTRL+C or right-click, choose Copy, right-click again and Paste it in your next reply.
  • Click Exit when done.
  • A log of the results is automatically created and saved to C:\_OTMoveIt\MovedFiles \mmddyyyy_hhmmss.log <- the date/time the tool was run.
-- Note: If a file or folder cannot be moved immediately you may be asked to reboot your computer in order to finish the move process.
If asked to reboot, choose Yes.


Caution: Be careful of what you copy and paste with this tool. OTMoveIt is a powerful program, designed to move highly persistent files and folders. Not following the directions as instructed or using incorrectly could lead to disastrous problems with your operating system.


Download AutoRuns and save it to your Desktop.
  • Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if your not sure how to do this.)
  • Open the folder and double-click on autoruns.exe to launch it.
  • Please be patient as it scans and populates the entries.
  • When done scanning, it will say Ready at the bottom.
  • Scroll through the list and look for a startup entry related to hosy77798.exe.
  • Right-click on the entry and choose delete.
  • Reboot your computer when done.

MoveIt output to the right window:

C:\Program Files\Common Files\hosy77798.exe moved successfully.

OTMoveIt2 v1.0.7 log created on 01162008_205504

I also ran the AutoRuns program. Just about to reboot and see if hosy77798.exe is still showing up. Will repost with results ASAP.

(Side note: I'm assuming that MoveIt allows me to remove files that windows won't let me delete because of a perceived dependancy or something... which is a handy little tool for some of the programs I've dealt with on here. And I'd guess that AutoRuns is an tool for editing the registry values for all the startup process without actually opening the registry. It is nice to have it all listed in one place. I'm going to do some reading on both programs, thanks for the help & the link!)

On reboot, Hosy77798.exe was still in my CTRL-ALT-DEL menu.

When windows first loads I know ALSO have the "Windows has encountered an error" window that pops up, asking if I would like to submit and error report. Note that it gives NO information about the error in question anywhere on the window itself. Perhaps I am just no seeing it, but I did click around and found nothing.

Upon closing this 'error' window, another identical window immediately pops up to replace it. This happens indefinitely.

If I open the task manager, go to Hosy77798.exe and 'End Process', this window ceases to appear.

A potentially useless side-note. Following the continued appearance of Hosy77798, I ran a search on the registry for "hosy77798", and found it in the following locations:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\*
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\exe

HKEY_USERS\S-1-5-21-2000478354-1292428093-725345543-1003\Software\Microsoft\Windows\ShellNoRoam\MUICache\

Note that there are the FOLDERS in which the registry value was located, and NOT the registry entry itself. I don't know if that is of any use or not. Probably not, but I thought I'd post it anyways.

Sounds like something else is on your system which regenerated that file. We need to identify whatever malware is present and the best way to start is by creating a hijackthis log.

Please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. If you can't perform a step, then skip and continue with the next. In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install the current version of HJT in the proper location.) If using Windows Vista, be sure to Run As Administrator.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
