Attentive Antivirus is a new fake antispyware program, the successor of System Doctor 2014 fake antivirus. Considerable system slowdown is what to expect of Attentive Antivirus scam. Nothing positive, in fact. The very fact of presence of this fake anti-spyware application is an evidence of a serious gap in the security of your system. Most probably this threat got inside of your computer due to the fault of your available anti-malware program to identify it on time. Otherwise, this is probably explained by the total absence of legitimate anti-spyware program on your computer.
