The "open with" box opens when I try to run files or click on desktop icons. I cannot access System Restore because an "open with" box appears. I cannot open Windows Security Center or add/remove programs as I get an error message "C:\WINDOWS\system32\rundll32.exe Application not found".
This started yesterday and seems to be getting worse. The antivirus software on the computer ran yesterday but did not pick up any viruses. I can't download a different one because nothing will run because the "open with" dialog box appears. Is this a virus?

Hello ErinGideon and welcome to G2G!

My nick is maliprog and I'll will be your technical support on this issue. Before we start please read my notes carefully:

NOTE:

• Malware removal is NOT instantaneous, most infections require several courses of action to completely eradicate.
• Absence of symptoms does not always mean the computer is clean
• Kindly follow my instructions in the order posted. Order is crucial in cleaning process.
• Please DO NOT run any scans or fix on your own without my direction.
• Please read all of my response through at least once before attempting to follow the procedures described.
• If there's anything you don't understand or isn't totally clear, please come back to me for clarification.
• Please do not attach any log files to your replies unless I specifically ask you. Instead please copy and paste so as to include the log in your reply.
• You must reply within 3 days or your topic will be closed

Step 1

Please download exeHelper to your desktop.

Double-click on exeHelper.com to run the fix.
A black window should pop up, press any key to close once the fix is completed.
Post the contents of exehelperlog.txt (Will be created in the directory where you ran exeHelper.com, and should open at the end of the scan)

Step 2

Download OTL to your Desktop

• Double click on the icon to run it (If running Vista or Windows 7, right click on it and select "Run as an Administrator")
  . Make sure all other windows are closed and to let it run uninterrupted.
• Make sure you check All Users option
  
• Under the Custom Scan box paste this in

netsvcs
%SYSTEMDRIVE%\*.exe
/md5start
explorer.exe
winlogon.exe
Userinit.exe
svchost.exe
/md5stop
%systemroot%\*. /mp /s
hklm\software\clients\startmenuinternet|command /rs
hklm\software\clients\startmenuinternet|command /64 /rs
CREATERESTOREPOINT

• Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
  
• When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
• Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them if you need to start a new topic.

Step 3

Please don't forget to include these items in your reply:

• OTL log
• OTL Extras log

It would be helpful if you could post each log in separate post
