How come I cannot connect to the Internet after uninstalling antivirus software?

by on December 8, 2010

Q: My ISP is Hughes net (Satellite). The problem I’m having is with my desktop. The operating system on that PC is Windows XP. I also have a laptop which has Windows Vista and is operating from a wireless “Netgear” router. This is my problem. On my desktop, which also connects through my wireless router, I’m not able to connect to the Internet. But yet, on my laptop, I have no problem connecting. This problem started after I uninstalled a antivirus program (from my desktop). Up until then, everything was working fine. I called my ISP tech support and they told me my issue was with my router after they supposedly checked everything at their end. I did also try to connect my desktop directly to my ISP modem, by passing my wireless router, and still was not able to connect. I don’t know if they were just telling me that just to end our conversation or if they were right. If it is a problem with my router connection to my desktop, how do I check to see if something else is blocking my connection? Any help would be greatly appreciated!

    What anti-virus software did you uninstall? Did you install or uninstall any other software around the same time?
    Is your desktop getting a wireless connection to your router?
    Have you tried:

    – Connecting your desktop PC with an Ethernet cable to the router?
    – Rebooting your Computer?
    – Rebooting your Router?


      I had installed “Avast” Anti-virus. After I did that, Avast pop-up said that it showed that I had another Anti-virus program installed, which I had Norton software, and that Avast said that their program would probably not work properly with the Norton software unless i uninstalled it. Which i did. Thats when I could not


      Sorry. Continue from last. Thats when I could not connect to the internet. I tried everyting you asked except rebooting my router. The reason being is because I am not sure how to do that. I hope you might be able to give me some guideance. Thank you for answering my original question.


    To reboot the router, unplug it and plug it back in again.
    Generally this is only something you’d need to do if all your computers were having trouble connecting to the internet. So don’t worry about that for now.

    Sounds like the problem is this Norton software that you uninstalled. Pretty common problem, I’ll just need to know the exact Norton software you had installed.
