I wonder if I did something wrong. I downloaded the recommended malware removal programs for XP and put them in a download folder that's not on the same partition as my OS. I thought I was downloading installation programs. When I double-clicked on Rogue Killer to install it, it simply ran without my hitting the Scan button. It was not an English version. At some point, it found a suspicious file and threw up a screen showing the normal interface of the program, including the Scan button as well as the name of the file it found, which was something in the Local Machine of the registry. The program froze at this point and spun its wheels for a long and so I just clicked on the X of the program to turn it off and it disappeared. It left a "quarantine" folder on the desktop but no "report". I tried to run it again later and found that it was "still running", so I opened the Task Manager and turned it off there. I then ran it again and it ran right through without finding anything. I lost my internet connection, tried another computer in my house and found that it was my computer that had lost the connection, so I returned the comp to an earlier restore point. Questions: Do you know why the program started before I could click on the Scan button? Did it put the file in quarantine because I forced the shutdown? Can I assume that the file it put into quarantine was necessary for my internet connection to function?* * File name: Type: PUM / Keytype: HJ Desk / HKEY Local Machine If the file is necessary for my internet connection to function, would that mean it is not a malware file? Or would it mean that my internet connection is dependent on the running of a malware file? Thanks for your help.
