bunch of viruses infected my computer!

heres what happened:

i turned on my computer.
logged in and stuff as usual
i go try and watch a video. it says it says i need a codec.
i feel suspicious so i search the codec on the internet, it turns out all good.
i download the codec…
avast says its a virus so i turn it off.
once finihed and installed my screen goes black.
a matrix gif covers my screen:
heres a simlar image:

then slowly all my desktop icons started to go away.
so i quickly retreated to avast safezone. the virus isnt affecting safezone.

so my question is. WHAT NOW?!

thanks in advance.

EDIT-
wrong section. sorry

Well turning off avast was a bad idea…

Can you boot into safe mode?(F8 on startup)

If you can go into safemode scan with avast and then removed what is infected and detected by avast. After that download malwarebytes if you can’t still log in normally, go to safe mode with networking.

www.malwarebytes.org

What OS are you using? And what other security software is on your system?

im using windows 7 home premium. no service packs installed.

and, every time i try and boot into safe mode it shows the desktop for a second. then just goes into that matrix gif.

i have failsafe installed. which i also turned off when it warned me of suspected external system control
i have avast internet security installed, which i told you about

by the way, im using windows vista on another partition.but it only has guest rights. i lost the administrator password and never bothered to recover it thinking i wouldnt need it.

When turning on the computer press F8, then restore, and select at least two days before.

System Restore does not remove viruses and or malware related problems.

Not even close…

so it WONT go away by system restore.
then what will work?

Essexboy will work ;D

he is notofied :wink:

Malwarebytes was suggested to you. Did you try running it? You can slso use a bootable cd. Kaspersky makes a great one.

Granted system restore will not kill the malware - but and not many people know this, it will remove the registry run keys created after the restore date ;D

:wink: So, more easy to work with the computer, isn’t it? I repaired some friends computers doing this, restore to few days before and then running tools like Malwarebytes, avast! boot time and others.

System Restore IS NOT a method for effectively removing malware. If that was the case we all would do that. You wouldnt need a real time av either if that was the case cause you could just do a restore but thats not the case.

Please read what I said - It does not remove the malware but it will remove the run keys … No run key and the malware is inactive, unless it is allied to a job, in which case it will be re-instated when it next runs… But there is a window of opportunity to use MBAM or some other tool to kill it dead

No Windows needed. Thats what rkill is for. Kill the malicious process and run MBAM.

::slight_smile: :-X

Okay Dieselman, you win. :smiley:

Windows Restore needed I meant.

Rkill will not always work I am afraid - however, I do it my way - you do it yours ;D

rkill does and always will work when used properly. rkill has been changing daily. Its an entire new program. You need to download a new version at least every 2 days to keep up with things. I make house calls all the time and rkill works every time. I have it portable on my USB stick but its not named rkill. I have named it “Malware Process Terminator”. If you leave it as is most of the time it will not work. If rkill cannot kill the process the I manually do it myself using Process Hacker. If you know how to spot malware you can remove it yourself. You can also use HMP Force breach mode. I also have been very successful using Emsisoft’s Emergency Tool Kit.

With a computer in front of me I have no problems - but working via a forum is a different kettle of fish as you have no idea of the OP’s level of knowledge, or if they will follow the instructions correctly. So you cannot rush the process

The think about the codec probably could be Trojan Zlob just run a scan with malwarebytes in safe mode like the other said

hope this helps!
