Generally speaking, Super AntiSpyware, Spyware Doctor and other specialist anti-spyware tools analyse the registry and other “deep dark” places within Windows to remove the remnants of deactivated trojans. avast! does not dig so deeply.
In the generally , several safe softwares are not good to system in a computer.
In usually ,Avast and system firewall is ok.
CHINA softwares enviroment is hard for spyware doctor .Some programs detect trojans were false positive.For instance,Avast had been considered QQplus is a trojan and cause a trouble to avast supporter in CHINA.Then Avast prompt resolve it when some people report it.
So,If your want a safe tools.Kingsoft antispyware and other domestic tools are proper parters for avast.
OK,well people are not going to like this,and I know Spyware Doctor has a loyal following,but when Malwarebytes,A-Squared Free,and SuperAntiSpyware + Avast all say my machine is clean,and a Google pack install of the starter edition of Spyware Doctor always finds a bunch of esoteric bugs,my confidence in the program does not
go up.
I thank Spyware Doctor is a bit drama inclined.
The problem is with information on the 50 trojans, etc. malware name, file name and location there is absolutely no way to conform or deny one way or the other.
