Hi guys ... i am facing a serious (may be not so serious) problem. Till yesterday i was using AVAST as the antivirus in my system. One of my friends brought a pendrive and avast detected some virus when i tried to open it directly from My computer. i scanned the drive after that, but my Folder Options went missing from the tools menu and Task Manager was also disabled within 2 minutes of inserting the drive for the first time. then today i installed AntiVir and it detected around 2000 infections. So i reinstalled windows after formatting the windows drive and installed Antivir again.
Now here is the main problem. I have 2 Mbps NU from tata. and my net is working a little slower (surfing) but the download speed i am getting has nosedived to 3-6 KBPS



(for FTP/HTTP connections) and 25-40 KBPS

(for torrents) from my previous speed of 210 KBPS (that i was getting till yesterday.
So wats happening ??? IS there any explanation ??? i havent updated XP (by automatic updates ) yet ... but this cant be the reason of this turtle walk, can it be ??
Please help guys .... its over my head ....
