A member on these forums recommended I try Roboscan since I was asking about 64-bit security solutions and this one sound promising, it has the Bitdefender Engine along with their own scanning engine so that's like layered protection... I tried to google a review about them but failed to find good results.. so here are a few questions: 1) Is it any good ? How are the detection levels? cleaning? 2) How bad does it affect system performance? 3) Since they claim to have 2 scanning engines, does that mean I ought to not install my MBAM Pro and setup exclusion as that would be overkill? 4) Does its firewall slow down your internet like ESS does or is it ok?
