Well hopefully this will be the final update!
I tried Avira - I could not get the definitions to update. I got REALLY MAD. I uninstalled it.
I did a system restore to completely undo everything which had been "fixed" on my computer by Comodo. This was good move because functions were back to normal. HOWEVER because I had uninstalled spy sweeper and mcafee, they came back. I decided to just go back to stupid mcafee because at least I would have some form of security - since nothing else seemed to work at all. Unfortunately, I could not remove the webroot program. I had to reinstall the webroot program in order to have the uninstall feature function. HA! Since I had upgraded the spy sweeper to the security essentials, when I went to reinstall the spy sweeper, the company had upgraded my key as well. I could only install the security essentials! I freaked because I was concerned that their program would kill my computer since my mcafee was reinstalled and it could cause major conflicts. I had to disrupt my internet connection so that the webroot program would not completely download, but would however download enough of the components to uninstall the program. By disrupting the connection, webroot would install what had been download but the program would not be functional. I restarted in safe mode and uninstalled the program. Then I updated to the newer version of mcafee. While updating I got a note that there was still elements of the webroot on my computer. Thankfully I got directed to a page where I could download the tool to remove webroot completely. I needed that terribly since I could not find it anywhere at webroot's support site. After I ran that tool, I got the mcafee on. I had to reinstall malwarebites again because just downloading the webroot in order to remove it corrupted the malwarebites. After I got everything installed, I took a break for a couple days.
Tonight I booted up only to have my mcafee program treat my public wifi network as a home network. I had never had this happen in my life. When I got up with mcafee's support they gave me a tool to remove the network. We went through this twice. Finally they booted me up the ladder and the realized that mcafee did not save my settings when I downloaded the newer version of their program and had upgraded trusting the public network. So we had to "untrust" it.
Good Grief!!!!!! Please may I never speak of this insane situation AGAIN!
The good news however is that my free subscription to Comodo is cancelled by confirmation and webroot has issued me a refund! Thank goodness.
