I have run hitman pro 3.7 and I found one virus. I still get redirected by a white S in a blue box. It is usually some advertising or a crappy website. I have windows Security and have run scans with no threat. Any Ideas of what I can do? Thanks.
You may also want to get a rescue disk from Kaspersky (one of the better ones) and boot to it and run it. That will allow the system to be scanned outside of Windows and potentially remove the source of the issue.
I would recommend that you never use any security product downloaded free from the internet.
I recommend that you use only a professional, all in on security system, that updates automatically, all day long.
I would recommend that you never install mismatched security programs, which cause system conflicts.
I would say that if you are using "free" security, your computer is largely UN- protected, and the security is full of holes.
I would say also, that the majority of infected computers, that I repair, have these "free" security programs installed. AND that these "free" programs did little or nothing to protect the computer.
