hello everybody,

well, i got infected by a virus last week(donno which one though but it was a trojan) and i cleaned my system and deleted the virus....but i cant understand what it did to my system......my avast home edition anti-virus(ad aware 2007 and windows defender for spyware) although installed is not being detected by the windows security centre and the downloads are also not downloaded completely....they get struck at say half way the progress bar say,i checked with the netlimiter 2 like if i download a 10mb file the download gets struck at 4-5mb and from then the transfer rate is zero.......i know this is a virus problem coz my downloads seem to be normal in bittorrent clients (i use utorrent)..plz help....

btw. am attaching a hijackthis report just in case if anyone would want it....

hello mahesh, and welcome to the forums. First off, you got infected by using utorrent and bittorrent and any other P2P sites, most likely. Those places are breeding grounds for viruses and malware.

I need you to upload a file to a virus checker and post the results, please.

First, please right-click on start, and choose Explore. Click on Tools, Folder Options, and then View. Make sure that there is a tic next to Display contents of System Folders, Show Hidden Files and Folders is selected, and Hide known file extensions is not selected. Now close Explorer.
Next, go to Online malware scan and upload the following files by clicking on the 'browse' button at the top of the page and navigating to the below files. Please post the results in your next post.

i use bittorrent clients only for media (music,movies,books& nothin else) and am cautious enough to scan it before even opening the files........

p.s. my friend too had this same problem...and he formatted his drive and the problem is gone but i dont want to format my drive as i have some important data in it.....so any temporary solutions....?plz...

and oh..!! transcend is my new 8 gb pendrive .....jfsw2launch.exe is its software.....so i think it is safe as it is a such successful company it wont cheat on its customer...right..?or will it..........www.transcendusa.com/

Bittorent clients work so fast-- because they bypass all your normal security software.
It only takes one infected machine out of hundreds to infect everyone--so everything spreads like wildfire.
You are often sharing files with places like China/Korea/Former Soviet states-- it is estimated that 80% of PC's in china are infected-- because people are uninformed due to government censorship--and too poor to pay for security software if they did know.

Bittorrent clients can be very useful between trusted network PC's -- but out there-- it's begging for trouble.
Infections expand exponentially... depending on that file's popularity--- and the number of previously infected machines in the data-link.

thanks for checking that out, mahesh.....even an old dog like me can learn something.

and ih8bills is right, as usual.....those places are indeed legit, but you need to be exceedingly careful navigating your way around there. My neighbor had some bad html that was injected into his browser and ended up with the midADdle bugger...always a fun one.

Regardless, let's see what combofix has to say:
