Recently I have been getting security alerts informing me that my firewall has been disabled. This has happened about 5 times starting about a week ago. When this has happened I simply turn it back on and all is well, until the next day and it happens again. I've run all three of my virus/malware removers, Spy-Bot, Malwarebytes and SuperAntiSpy and still have the problem. As far as I know, everything is up to date on my pc, and is basically clean and operates very well. Also, recently, my yahoo email address book was hacked and the addresses there were used to send advertisements, supposedly supported by me. Now this! I googled this subject but there doesn't seem to be much on this subject. I suspect there is a virus lurking within my pc. Any help would be appreciated....Steve in Connecticut.
