Thats the suggestion I already got from my ISP  help center . If
reinstalling is the only way to survive then how good is linux from
windows .


Any ways a thanx a lot for hearing to my problem .I ran clamav on  my
mounted windoes partitions and found two more trojans .so cleaned it
all .

Regarding my linux box , I am now getting an almost stable connection
upload download ratio has improved to 1:16 approx. Didn't find
anything specific .

BTW can you provide some links from where i can get some know how
regarding forensic analysis so that i can at least do the necessary
test when machine is attacked again in future .
