Windows 7: MSE will not install after a bad uninstall

29 Aug 2015   #1

Windows 7 Professional 64 bit
MSE will not install after a bad uninstall


For a few days when MSE ran a full scan it would always get caught up in the same place. So, I got the idea that I'd uninstall it and reinstall it. I uninstalled and rebooted. When I got back the icon was still on the bar. It is red and x'd out. When I click it says it is off and my computer is in danger. It will not turn on. It does run a scan. I looked in program and features and it is not listed. I tried to reinstall it, and now there is an error that it can't be reinstalled. Please help.

*edit to provide more info - Prior to this when a scan was failing I'd stop the scan. It wouldn't stop and when I tried to close the icon, it wouldn't.

Thank you.

I followed the instructions that I could. There were things they wanted me to delete in the registry that weren't there. I restarted the pc and the mse icon wasn't on the bar. The notification flag then told me to turn it on, so it's still here. I tried to install anyway, but I couldn't.

Malware or a virus (that MSE can't deal with) has possibly stopped MSE from re-installing.
