It is a pitty that Avast having a good antivirus program, sells a defective product loke this (Grime Fighter).
You should stop selling a deffective product like this.
This type of issues will rest credibility to AVAST and will definitevly affect selling antivirus products. ( I am one of the them).
If you want to create an anti-troyan, backdoor product, make it as a stand alone like your antivirus with regular updating. I think it is a logical thinking do as I say. Just think about it.
Stop selling this product . I bought 2 for 2 computers, could not make it intallation in my laptop, could installed it in my desktop but doesn't work because tell me to connect to the internet when the first thing my computer does at starting is connecting to the internet. Explain me this issue because I am connectet to the web ( by wire) and this Grime Fighter request me to connect to the internet when I am way long connected to the web.
