how do i acquire a definite identity if avast will not deliver it; i will need to use a different brand of av scan – what do you recommend?

Effectively how would avast know who to send any info to, as any information passed would I believe be anonymous.
avast and i can elect to waive anonymity -- what don't you understand?!!! and what do you mean by "[i]believe[/i] be anonymous" -- don't you [i]know[/i]?
However, that doesn't stop you a) answering the questions asked relating to the detection, file name and location, etc.

It also doesn’t stop you using google, etc. to look for information on the above either. Finding out if it is a) a legitimate file name and location, b) an application that you are aware about and installed, c) what it is that this application does that might make the anti-rootkit scan consider it ‘suspicious.’

as usual, i have no idea what you’re talking about! we have an expression in english: “if you can’t dazzle them with brilliance then baffle them with bullshit”
