I have searched your forum and found one similar problem that had been posted several years ago. Did not help
I had free version of AVG and Malwarebytes on pc. While on internet AVG came up saying Trojan Virus had infected my pc. Then top tab showed "Win 7 antivirus 2012". AVG then offered to sell me their $59.99 version; so I thought this might be fraud virus just to get me to buy their program. I closed out internet connection, uninstalled AVG and Malwarebytes (also used AVG's tool to uninstall complete program later). I could not access internet until I had uninstalled AVG.
I went back online and installed Windows Essentials, Essentials found 4 virus including Trojan and deleted.
Now I do not have my firewall. I have googled problem and have tried every suggestion. Even a Microsoft tech could not figure out what the problem was, he accessed my pc and went through and tried things I had already tried, plus some things. So I still am without firewall.
I have windows 7, 64 bit.
When I googled problem yesterday, I saw someone else had similar problem this month and received suggestions.
"Windows Firewall" does not show up under "services", to start or stop program.
I'm not geeky, but I try to follow instructions to fix problem. Is anyone else having similar problems at this time?
Any help would be greatly appreciated.
