HI Vishal , thanks for the reply ,
1. RAR is indeed not present there , which i had tried earlier already.
2. Removing RAR from IDM , did not help. As I have deisabled monitoring of FF / Mozilla from IDM.. so its not IDM which is catching the RARs , its FF which is feeding IDM the RAR

so to say ..if u catch my drift!
Any trick like Editing the registry or somehow edit the config file of FF may do it right ? I have no idea...
Any other suggestions Mr.Vista ?

... ANy will be welcome ! I am loathe to format right now.... otherwise... i wudn't have taken the pain! With my incremental's backup in place, getting a previous state will be a breeze.. Unfortunately my HDDs are almost full to the brim , and formatting is not an Option!
Thanks!
