trojan 2 - 0 quek

what r the odds of being infected by the same trojan 2 times in a row?? i think i'm the only 1 that is soooo 'lucky'... but ytd after restoring my pc to an earlier date, and disinfecting my pc, everything went back to normal... but this evening when i came home, i was still surfing normally... till my bro wanna use my pc... during that time i went to bath...

but when i came out and enter my room, to my horror the same trojan was attacking my pc again... my 1st thought was "what website did my bro visit?"... he said only friendster... but i gone into friendster and no trojan... how come he went in n after that there was this trojan again?? i can't blame him, yet...

1stly... the trojan might not be completely removed from my pc ytd

2ndly... it might really be that the trojan came from friendster, as i got the same trojan ytd after visiting friendster...

3rdly... the trojan attacked almost at the same time at ytd, around 7pm...

lastly... it could be due to the keygen i downloaded on 20nov, but the trojan from that keygen was blocked, maybe it wasn't fully blocked...

i'll need to monitor my pc activities from now... and to prevent me from pushing the blame to my bro... i would need to restrict him from using my pc till i am sure the trojan is gone...
