Actually I was just kidding - I gather from your posts in the 98 group that
security is a special area of interest and expertise.
Yes I use Avast - but why is it a false positive if I can see that the file
extensions in the T-M SysClean folder, including the sysclean executable
itself, have beeen changed? Note that just to make sure that the same
problem would not recur, after the Avast scanner removed sysclean.exezz I
deleted the entire folder, downloaded new components, and ran SysClean again
from a new temporary folder. All the file extensions were normal.
