Hello! My McAfee enabled computer was exposed to an unsecured public network recently. The first subsequent use showed no difference from a healthy computer, but that was the last normal use. Upon connecting to the internet, via wireless and wired connections, while booting in safe or in normal mode, it seems to start a short time-count after which it restarts automatically. Failed approaches: 1. A system restore to older points has made no difference. 2. In a hurry to resume normal use, I backed up all personal data and restored to factory settings, hoping a fresh image would result in resumption of the original state. This made no difference. I now have no AV software installed. Searching similar topics on techspot reviels close similarity with several older cases, but since they all had different solutions, I hesitate in directly trying one particular solution without advice (which I would greatly appreciate).
