my problem is that i cannot download any thing from the internet browser and can surf internet normally only cannot download any thing (can download files from p2p programs). a program sysupd.exe was running in my task manager, whenever i kill this process it automatically starts again and i was not able to delete as it was running. somehow i managed to delete it from safemode still the problem is there. i scan my system from nortron and mcafee; no virues found. and getting a lot of port scan every hour (may be back door) tried to get what ever info required from net what was not usefull. i am jammed cannot download any file from the internet browser.
your advice w'll be highly appreciated
