thought it worth just saying that, with the A 2 program it sometimes brings up results that are called "false positives" so it is adviseable to know what is on your machine and , when the scan is complete, to read through what it finds as some of it will probably be legit (as in my own case where a lot of what is produces is completley legit)
if; when you have done a scan with it and are unsure of a result, there is no harm in asking either on here or on a non malaware forum for advise as to whether a result IS worrying or not;far safer and wiser NOT to remove it unitl you have had it confirmed as a nasty
it can be treated sometimes like an HJT log; just because a line LOOKS suspicious does not mean that it IS
if in doubt ask about the results
