I have a Dell OptiPlex 3010, which is about 6 months old & has Windows 7 on it. We use Internet Explorer 10 as our web browser, as my husband has sites bookmarked on it that he does not want to lose. Also, we have Norton Antivirus software on our computer, & it scans weekly for viruses, etc. Recently, we have developed some problems with the computer & cannot resolve them. I will outline them below.
(1.) We have had spotty access to our e-mail via CenturyLink. Usually, when I try to access it the first time, there will be a popup from Centurylink or some other adware. The second time, I receive the HTTP 400/Bad Gateway message. Just now, it has finally loaded. This is the first time since probably Wednesday. Go figure...
(2.) We are having numerous pop-ups, ranging from needing to upload Internet Explorer 11 to anonymous surveys. The pop-ups occur when I go to a website & then try to navigate the website. I might click on a box to enter my password, & an ad or survey pops up.
(3.) I cannot uninstall programs that I feel are unnecessary or may be the source of the pop-up activity. Whenever I go to the "Uninstall" screen & attempt to uninstall a program, a box pops up, saying that I must be the administrator to uninstall the program. The things I want to remove are Gorilla Price, Homenet Manager (My husband thought we needed this to replace Network Magic but found out we don't need it.), & Trend MicroClient/Server Security Agent (We don't need this. We have Norton.).
I am thinking that I inadvertently downloaded something on my computer that created the pop-ups. It's so hard to know what is safe & what isn't.
Additionally, my husband tried to work on my computer last night, & he made two discoveries: #1 - Somehow, two users are running at the same time on my computer. He had set it up where I would be the only one (or so he thought), & I don't even need a password to access the desktop. This is probably the reason for the problem with uninstalling programs. #2 - Two antivirus packages are running, apparently, Norton & Trend. I don't know where Trend came from, unless it resulted from a faulty download.
Does anyone have advice for how to fix this? Fortunately, my files are on an external hard drive, so hopefully, they are protected in the event of some type of purging activity that may have to be done. Thanks, in advance, for help!
