AV killer?need help!

i need help with my pc. im using winXP i noticed my AVG and The Cleaner wont run,i suspect an AV killer preventing me from using my anti virus sofware,i cant access MSCONFIG either,i cant uninstall my AVG nor can i install.is there any way i could fix this before i resort to reformating?what are other free reliable AV software i can use?please help...

 

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

Let us know how you go...

Cheers

 

Click on the online scans in my signature and try a couple of the free online scans like trend micro http://housecall.antivirus.com/ or http://www.kaspersky.com/remoteviruschk.html and see if that will help then post back and let us know the results

 

i cant go safe mode,when i press f8 it only toggles a boot sequence menu,i try the online scans...

 

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:

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

 

ill try that THANKS A LOT!

 

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

 

Try a TDS-3 Process Memory space scan
