System Check Malware/Virus?
« on: January 18, 2012, 06:10:16 PM »
I am running Avast Free.  My computer has been infected with "System Check."  Why did Avast tell me I had a problem and yet not stop it from entering?  I am also having a horrible time removing the problem.  I got the majority of it gone, but there must be some more code in the registry that is still misdirecting my web searches.  Can anyone tell me what is going on and offer advice for a fix?

Sorry if I posted in the wrong area.  I couldn't find a specific virus section.

Thanks for the help, but I already followed the instructions from bleepingcomputer.com.  I had to perform some additional steps, but I finally got rid of System Check.

I am still wondering why Avast let me down.  I was hoping for some insight there or I will likely change to a different anti-virus program.

Thanks anyway.  Guess you didn't understand my question.  I'll look for help elsewhere.

Alas that will do no good - over the last three days I have cleared systems with the following AV's from this malware

AVG
Norton
McAfee
Trend
Panda Cloud
ESET
Kaspersky
MSE

Is there a reason that a lot of rogue antivirus programs get past the regular antivirus? I used nod32 before avast and it let a rogue through too. In particular, if things like malwarebytes can remove a lot of these things easily, why can't the regular antivirus?

Err, not to sound like I'm complaining, I like the product. I'm just a tad curious here.

There is no security programs with 100% detection.....
lots of Rogues are also not detected by malwarebytes.....i know bc i find and upload some of them    ;)

Look here  "razoreqx"  is uploading a new Rogue.FakeRean sample to Malwarebytes......click the Virustotal link he have posted there.....you see  no one detect it  ;)

If you could not remove this System Check virus with Malwarebytes why don't you try other anti-virus tools which are free? For example, Superantispyware? This a good malware remover and it is free. Try scanning with Superantispyware and see whether this will help you.
Do you see your icons at the desktop? Do you see the shortcuts? If not, then press "Win + R" and insert "iexplore.exe"  Internet Explorer would open, this is where you may start downloading some anti-virus program like Superantispyware, for example. Here is what I mean:
http://www.deletevirus.net/system-check-virus-removal-tool/

Did you manage to recover your files? Actually, the site BleepingComputer gives good recommendations on how to restore your hidden data.

You say you performed other additional steps but didn't specify them. Can you please let us all know as, I too, have now got this virus. Thanks.

Konfoozed welcome to Avast! forum

I do not think jeanbBFE is going to answer since this thread is two weeks old and he/she said was going for help elsewhere.

If you were not able to get rid of system check by following Bleepingcomputers instructions

http://www.bleepingcomputer.com/virus-removal/remove-system-check

You should follow this instructions to generates the logs to assist you in cleaning your comp:

http://forum.avast.com/index.php?topic=53253.0

and attach logs for MBAM, OTL, and aswMBR.exe here:

http://forum.avast.com/index.php?board=4.0

where Essexboy or Oldman will help you out.

Good luck.

Thanks for the response and the welcome.
Yes you are probably right that he/she won't respond.
I do find it a little irritating that someone asks for help...then says they've solved the problem by taking additional steps but doesn't bother to inform the forum of what steps were taken! Anyway, I intend having a go tomorrow to see if I can resolve the problem by using the advice offered by bleepingcomputer.com and will seek further advice if necessary from forum experts as you suggest.
Before I start I would like to know if I really must boot up in Safe Mode with Networking rather than Safe Mode. My computer is not part of a system and I don't have to log on ever. Further I would like some advice regarding the fact that my computer has two hard drives in a dual boot arrangement whereby I opt for whichever Hard Drive I want when the Bios screen opens. As both Hard Drives are infected I assume that the virus is in the Bios. As you can doubtless tell, I am very much a newbie.

Konfoozed.

The advice given to boot in safe mode with networking is only to download the programs they ask. This is if you do not have any other means to get at those programs, otherwise you can use another clean PC, and download the programs and transfer them to the infected PC.

Since I am not a certified malware removal tech, I can't give you instructions on how to proceed; However, the fact that you have a dual boot system with two hard drives, It would be better to seek help in the Avast viruses and worms forum as I told you above.

BTW and this is important. Do not clean yor temps or use any program to do such jobs. This kind of infection will store ( hide ) some of your own files in your temp folder.

Regards.
