heres a link for you with manual instructions,
http://www.securemost.com/articles/trou_3_remove_c2_lop.htm
it involves using the registry
editor, once in there do a backup of the registry (file>export to wherever you fancy)
go start > run
now type regedit in the box and hit enter
just go very gently and measure twice cut once
There are two keys to negotiate to, this is the first one (just follow the path)
HKEY_CLASSES_ROOT\clsid\{7b49a2a5-b45f-46f3-ac60-2578477671ee}
the element your removing is this one in the first key (right click and delete)
{7b49a2a5-b45f-46f3-ac60-2578477671ee}
then the second one
HKEY_USERS\s-1-5-21-796845957-842925246-1060284298-500\software\trinityayb
remove this element in the second key
trinityayb
heres the site I got the keys from, they suggest etrust pest patrol but I dont think thats a freebie but yu can check
Its a good plan to turn off system restore first. (control panel>system>system restore and check the box)
Hope it works for you ok
