Yetersday my husband decided to download the Firefox setup from the offical site and try to install it. I guess he got a little impatient and click the download link several times, because now I have seven copies of the setup file, three in "My documents" and four on my desktop.
All seven copies are incomplete, their file size is zero. If I try to delete them, I get the following message:
Cannot delete FireFox Setup 1-3.0.7: It is being used by another person or program.
Close any programs that might be using the file and try again.
If I try to run it, I get the message:
C:\Documents and Settings\Owner\Desktop\Firefox Setup 1-1.0.7.exe isnot a valid Win32 application.
My husband downloaded this through Netscape. So I thought netscape might still have a hold of the downloads. I cleared everything from Nestcapes download manager and even ended up uninstall Netscape. I still can not delete the files.
I thought it might be spyware, so I went through the instructions found in the post: Malware Removal - HiJackThis Logs Go Here
When I downloaded CWShredder, windows told me that it was not a valid Win32 application and I could not run it. I check the file size, it looked complete. I download it again, and tried to run it. Same error. To my relief, I was able to delete the program.
So I skipped the CWShredder program, continue through the rest of the steps and cleaned up whatever spyware that was found. Rebooted and Windows XP still doesn't like CWShredder. It still won't let me delete the empty Firefox setup files either. I am at a loss as where to go from here.
