You are possibly infected with malware.


Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

It is a self-extracting ZIP file that contains the Kixtart Script Interpreter {
http://kixtart.org Kixtart is CareWare } 4 batch files, 6 Kixtart scripts, one Link
(.LNK) file, a PDF instruction file and two utilities; UNZIP.EXE and WGET.EXE. It will
simplify the process of using; Sophos, Trend, Kaspersky and McAfee Anti Virus Command
Line Scanners to remove viruses, Trojans and various other malware.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you can
download the files and perform a scan in Normal Mode. Once you have downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
file. http://www.ik-cs.com/multi-av.htm

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
FireWall to allow it to download the needed AV vendor related files.

Go to Start -> Run and enter regedit.exe in the Open box. This
should, and I stress should, run the Registry Editor.

Regedit.com is not a legitimate Windows file. It was probably
put there by some sort of virus/trojan/worm. In other words,
your computer is infected. You're probably going to find a
number of other bogus files that have the .com extension.

Make sure your antivirus program is up-to-date and run a scan.
You should also run a scan with AdAware and Spybot S & D.

AdAware

Spybot S & D

Next, you might want to visit some of the online virus scanners
and see what they find:

Run both the AntiVirus and the AntiSpyware scan on this site:
http://housecall.trendmicro.com/

Click on the "Scan your PC button" while holding down the CTRL
key (to override any popup stoppers):
http://www.pandasoftware.com/products/activescan/com/activescan_principal.htm

McAfee FreeScan
http://us.mcafee.com/root/mfs/default.asp?WWW_URL=www.mcafee.com/myapps/mfs/default.asp

Symantec Security Check
http://security.symantec.com/sscv6/default.asp?productid=symhome&langid=ie&venid=sym

Good luck
