I had a virus, had it removed, it returned, through this forum I downloaded a stinger & malware tool that fixed the problem - NOT - Every Saturday mornign for the past several weeks I have a message from McAfee that my computer is at risk and it is always the same 2 viruses, PCViewer & Reboot. I have been repeating the steps using the same stinger & malware downloads. How can I completely get rid of these viruses?
The logical question would be what are you doing just prior to this or have you noticed anything 'updating' in the background?
What software are you using for full-time antivirus and firewall protection & what is the name of the 'malware download' you used?
Stinger is a specialised removal agent only for certain infections and unless you have exactly what it is designed to remove it wont help.
I suggest running the free version of THIS software and update before running. Let it remove anything it finds and reboot immediately if asked to.
