    Try booting into safe mode and then running a scan with AVG

    Let us know how you go...

    Cheers :D

    Ok, let us know how you go...

    If you are unable to do the online scans, then try downloading a copy of "Stinger" from here:

    Let us know how you go...

    Cheers :D

    i tried Bitdefender,and detected Backdoor.SDBot.Gen which was repaired,then Trojan.Qhosts.B w/c was found on C:/windows/system32/drivers/host,i tried to scan it with Dr. Web and it turned out to be a Win32.HLLW.Agobot.3 internet worm (no wonder my PC just slowed down together with my internet connection),it said it went under the name LSAS.exe that can be found on C:/windows/system32,i only found a LSASS.exe.Bitdefender couldnt repair it btw,so i tried stinger,it detected the TrojanQhosts.B and repaired the infected file,it detected another one DcomRpc.Gen trojan and deleted the file,made a 2nd scan with Bit defender then with stinger,no more viruses detected,i think its ok now,my problem now is how to make my AV run again,and to beable to access msconfig and windows task manager.i dont know how to repair the registry.

    You might try reloading Windows over the top of itself.

    Hope this helps...

    Cheers :D

    Please keep us informed how it goes.

    You mentioned the HOSTS file? If you look at that, anything strange? Can you access every site normally? If not, rename the HOSTS file and try again.

    If the AV blocking infections have gone, can't you just run the AVG and other functions normally?
    I would recommend to try one or two different online scanners too, as all have their own detections.

    Is/was going back to an older system-restore point no good option for you?

    BTW: also make sure your folder settings display all hidden files and extensions, to ease finding files for you.

    as of now i have no problem accessing sites,by the way the host file was under C:/WINDOWS/system32/drivers/etc/host,and not c:/WINDOWS/system32/drivers/host,it was already repaired,with stinger.i cant restore my pc since i turned off system-restore when i was scanning,so to prevent the virus from being saved together with the restore points,thus keeping it from getting removed.i tried restarting the AV still aint functioning.i guess il try more online scans.... :(

    If this is your only problem, then try uninstalling your AV, delete all traces from the registry and reinstall...

    Cheers :D

    I would assume that one of the baddies is still running

    In this case and only this time as we don't normally do HJt logs here any more please do this and I will look over the log and advise if we can fix it

    go to http://www.thespykiller.co.uk/files/HijackThis.exe and download 'Hijack This!'.
    make sure it is placed into it's own folder, not a temporary folder. Then doubleclick the Hijackthis.exe.
    Click the "Scan" button, when the scan is finished the scan button will become "Save Log" click that and save the log.
    Go to where you saved the log and click on "Edit > Select All" then click on "Edit > Copy" then Paste the log back here in a reply.
    It will possibly show issues deserving our attention, but most of what it lists will be harmless or even required,
    so do NOT fix anything yet.
    Someone here will be happy to help you analyze the results.

    I've moved this to trojans and backdoors as I strongly suspect that there is at least one agobot or sdbot if not more still active
