Hello expertblr,

Thumbs.db is a windows hidden file that stores a cache of thumbnails for a folder.  Normally found in folders that have video/pictures..but I've seen it in lots of other folders....

Why do you think this file deleted you mail archive????

Thumbs.db is harmless...

If it is bothering you then turn it off.

In Explorer, go to Tools -> Folder Options or open the Folder Options icon in the Control Panel.
Choose the View tab, and turn off the Do not cache thumbnails option.
Click Ok.

Thanks,

I agree.

I would check for viruses and malware

Have you tried running virus scans and spyware scans  This could be a problem with viruses/trojans/spyware or other malware. Some free online virus scanners:

Also try these free programs to rid your system of spyware, trojans, and other malware:

Spybot - Search & Destroy

http://download.com.com/3000-2094-10045910.html?legacy=cnet
LavaSoft Ad-aware  

I use BOTH of the above programs on my 3 Windows systems; what one program misses, the other catches.  Also make sure to download the most up-to-date data before you run the programs.

Another very good freeware program for ridding yourself of spyware is this:

You might also try this free program (HijackThis) -- install it in its own folder, don't download to your Desktop:

http://www.spychecker.com/download/download_hijackthis.html

HijackThis is a tool that is for advanced users, because it lists all the installed browser add-on and startup items, allowing you to inspect them and then optionally remove any ones you select.  You must be careful in choosing what to remove, although the program can create a backup of your original settings.  But put a check mark to fix any home page or search page setting that HijackThis detects which you have not entered yourself.  The program has an option to download online updates of the hijack data.

You should first post the log at this site:  

http://www.hijackthis.de/index.php?langselect=english

and it will be automatically analyzed for you (after you click on the button labeled "Analyze" near the bottom of the page), telling you which entries (called "Nasty") should be fixed.  You will also be told if you have any items that are "Possibly Nasty", or "Unnecessary", or "Unknown". If you don't know what to do about these, you might find something on the module name by doing a Google search of the internet.

If you have any questions about what it is asking you to fix that you would like the E-E experts to comment on, then do this:  right above the Analyze button you will see this message: "The following analyses has been stored temporarily", and there will be a link where the analysis file will be saved (for a period of three days). Click on it and then copy the link of that page from the address bar of your browser and paste it here, and experts can check it for you.  (Please DON'T post the entire log itself in your question.)

In case you would like to learn more yourself how to use HijackThis, here are a couple of urls:
