There is a similar topic http://forum.avast.com/index.php?topic=25822.0
Use this tool to scan your PC - http://www.f-secure.com/blacklight

You probably still have an infection, probably a rootkit on your system that is killing avast.

After running the above rootkit tools if nothing is found try these.
If you haven’t already got this software (freeware), download, install, update and run it, preferably in safe mode.
AVG anti-spyware or SUPERantispyware or Spyware Terminator.

thanks for helping !

F-Secure is loading, we gonna see.

The anti rook kit from Panda, is recognized as “unvalide win32…etc”

We gonna see.

F-secure corrupted … I´m gonna try SUPERantispyware right now

Hmmm… maybe you should boot in Safe Mode and try on-line scanning before it’s too late…

Kaspersky (very good detection rates)
ESET NOD32
Trendmicro housecall
AVGas (does not necessary if you have AVG antispyware installed)
F-Secure
BitDefender (free removal of the malware)
HitmanPro (multiply scanners)

Superantispyware empty the memory 2 times. I´m gonna do this right now so ! Thanks

Bit defender online is scanning, anyway, I think I´m gonna go to sleep for today… Let´s see tomorrow.

Thanks…

olà !

So right now, he (bitdefender online) has found

theses ones :

Infected with: Win32.Bagle.SUK, Win32.Beagle.FQ, Win32.Bagle.SUA@mm, Win32.Bagle.STX@mm,  Win32.Bagle.196, DeepScan:Generic.Malware.SYddldg.5D1B78EB, Application.Dialer.EL

and it´s going on. Let´s see later if the PC let me use security programs.

Xo bitdefender online finished its analyse and I have 6 indentified virus, 66 infected files,

the ones I didn´t mentioned before :

Infected with: Rootkit.Bagle.G
Win32.Beagle.FQ
Trojan.Bagle.DR,

So Bitdefender deleted the files, but I hope it has ot deleted important files.

What can I do now ?

11

impossible to start in safe mode, impossible to launch avg anti root kit ?

Is it the end for me ?

Do I have to post a Hijackthis here ?

thanks

Bagle infection is one of the worst for antivirus… it blocks cleaning…

What do you get when trying to boot in Safe Mode?

13

oh, That´s a horrible one !

Então,

When I try tp launch Xp in safe mode, it´s simply boot back, blue screen… just before it´s written, "press esc to cancel loading sptd.sys’’
