Windows 7: Please Help in Identifying Recurring Locked Temp Files

Please Help in Identifying Recurring Locked Temp Files



Lately these 3 locked Temp files have been appearing every day even though I unlock and delete them. They are 640KB, 1.8MB and 1.8 MB in size.



The LockHunter program which I have been using to unlock and delete these temp files says that they are being locked by C:Windows\system32\DllHost.exe. I just scanned the computer using both Emmisoft and MBAM while these files were in place and there were 0 detections from either scan.



I just discovered that 3 more files along with Java's hsperfdata temp file have appeared within the last 10 minutes. These have contents of 3.68 MB, 640 KB and 2.25 MB in size.

I'm hoping that someone will be able to identify the source and purpose of these persistent locked temp files that keep showing up in my computer's AppData> Temp file.

Thanks for your help; Maxx

Many programs create temp files. If the scans you have not found any malware, then you have no need to be concerned. It is a good idea, from a maintenance perspective, to clean out temp files from time to time. There accumulation can have a negative effect on system performance.

CCleaner is a very good temp file cleaner

Most likely, the reason that they are locked, is that they are in use by the app that created them. If you can identify the app, then you may be able to prevent these files by the apps settings.

EDIT: If you can use the right click menu to access their properties, it may identify the app that made them.

Hi, Maxxwire.

Since hsperfdata is a Java file, I suggest that you make sure you have the latest version of Java installed on your computer and that all older/vulnerable versions have been removed. The current version is Java SE Runtime Environment (JRE) 6 Update 25.

I also suggest clearing the Java cache: How do I clear the Java cache?.

Corrine- Thanks! Upon your advise I used Revo to uninstall Java v6.0.240.7 (from 4-13-11) and then installed the latest iteration v6.0.650.6.

The details pane available through the context menu gave no clue as to what program created these Temp files, but as you indicated going into the Java Control Panel revealed a way to stop the Java program from storing information on the computer and since I rescinded permission to store files on the computer there have been no such files appear in AppData\Temp which indicates their original source.

I confirmed that these Temp files were placed by the Java program this morning by briefly allowing and then immediately turning off the permission again which created the first 3 of these Temp files since I originally turned off the permission for them to be created on the computer yesterday afternoon.

I have now returned the program which uses Java back to full use and so far only Java's empty hsperfdata folder has appeared. I will post back if any of the Java Temp files show up again...

Is having temporary files that much of an issue?

I'm not concerned that there are files in the AppData Temp file because that is what it is used for. What I am most concerned about is the identification of these files. In my experience most temp files are fairly easily identifiable as to the program which placed them there, but since there is absolutely no indication of where these files came from or what they are being used for it raises a level of concern on my part especially after my computer started malfunctioning as it never has before.

Last night Explorer quit working properly so I tried a system restore which has worked every time that I have used it in the past and I was shocked when system restore failed for the very first time ever in Win 7 x64. I was finally able to do a Macruim Reflect image restore at about 4:30 am, but today I just noticed a completely new set of 4 temp files (screenshot attached) appear in addition the perfdata file none of which I've ever seen before and there is absolutely no indication where they came from either so yes, I am concerned about that considering the unprecedented problems I had with the computer last night especially since I have prevented Java from placing any files whatsoever anywhere on the computer which makes me all the more uncertain about what these 11 constantly incarnating files in the AppData Temp folder which so far have appeared as locked files, unlocked files and even an XML file are doing there and if this is related to the most serious malfunction I've had with Win 7 to date which occurred in the midst of the same 24 hour period that all of these before unseen AppData files appeared especially even though the computer continues to scan clean.

I want to thank everyone for their help, but I have decided not to continue to use this Java based program any longer in that in the beginning it seemed like a convenient way to download operational files from the internet, but it has turned into such a hassle that I have decided that I will continue to do the download once a day manually (which as it turns out is all the program was doing anyway) which process only takes a couple of minutes anyway. As a result I have uninstalled both the Java based program as well as Java Runtime which I only needed to run that one program with anyway in that my Opera browser already has Java onboard.

Again, thanks for your help, but having the 'convenience' that this program offers is just not worth all the hassle it has become. Hopefully the unique problems that my Win 7 x64 computer has been having during this period will cease and I can get back to enjoying the new Intel 320 SSD I had installed in it just 2 weeks ago.

I thought that this was all over after Java was uninstalled, but a few minutes ago another mystery temp file showed up in the AppData Temp file. Both HitmanPro and MBAM say that it is not malware, but interestingly enough during the MBAM scan another temp file shows up next to it and then disappears when the scan is complete. There are as many as 4 more phantom files that will appear briefly and then disappear. I'm really curious now as to where these temp files are coming from and why they have been placed there.
