I have been having issues with my computer starting about a month ago. I use Norton Internet Security, and about a month ago Norton began showing repeated messages that it was blocking attacks by the 3 virus/Trojans listed above. I do not however, believe that it was actually doing so. Soon after these messages began, my computer started becoming increasingly slow. Since then I have used the infected computer very minimally (ex: to retrieve a file/document I only have saved on that computer, etc.) as I have a second one that is fine, but I would like to try and solve these issues. I have done a little research and it seems other people are also having this issue. Likewise, I have also noticed multiple dllhost*32 processes and other unfamiliar processes showing up.
I apologize in advance, as I am not particularly computer savvy. I have reviewed the "Preparation Guide for Use Before Using Malware Removal Tools and Requesting Help," however I have had some issue with steps 5 and 6, and I am unsure of how to proceed. First, regarding step 5, my computer does not give me the option to enable the Windows firewall, as it shows that Norton Internet Security has control over those settings. Is this ok, or do I need to disable NIS and enable the Windows firewall before proceeding? Second, regarding step 6, I did go ahead and try to download the DDS tool from the link in the "Prep. Guide" post, however after clicking on "Download Now," I receive a pop up message box titled "Security Alert" that says "Your current security settings do not allow this file to be downloaded." Do you know how I can go about altering my security settings so that I can download the DDS tool?
The infected computer is painfully slow at the moment. From the time I turn the computer on, it may take me about 15 minutes to simply open the "Preparation Guide" webpage, click the link for the DDS tool download page and wait for that page to fully load.
Thanks in advance for you help,
