:cry:
Hi I am a new member and hoping desperately someone can help me,
as I have tried all I know.
I had to reformat my hard drive and when I went into windows update
to try and download sp2 again. AVG started popping up saying that
msdirectx.sys had a trojan horse collected.5.L. I deleted it but it
replicating itself. Causing programs to not open and booting me off
the internet and I could not disconnect without turning the tower
off at the main.I have tried online scanning to no avail as pc
keeps being shut down. The latest scan showed the trojan horse
collected.5.L was back and also in Windows\systems32\bot.exe was a trojan horse
IRC/BackDoor.SdBot.172 & trojan horse Downloader.Istbar.6BU. I am not sure whether all deletes were successful though.
On boot up I had two of the same login panels as administrator.
I finally managed to get into msconfig and and noticed to csrssa.exe
I have never noticed them there before so unchecked them to start on
bootup, I have a feeling they are connected to that csrssa.exe.
I am scared now to go back to windows update even when I can clean my pc but I do so want to get sp2 for XP Home Edition. back up and running as at the moment I feel I have very little protection.
I have run this Hijackthis file and attached it here, but do not want to touch it any further until I know exactly what is needed to be done with it.
Sorry I cannot do an online scan at the moment as something is preventing it from scanning my pc
Sorry for babbling on but wanted to explain as clearly as I could as to what was happening.
