Need help removing virus/malware


38 posts in this topic

Posted

Ok, I'm fixing a pc for a friend. When I turned on the computer I was blocked out by some dumb message about copyrights and wanting to pay $200. Finally was able remove some of the files, delete from start up, etc. installed spy bot search and destroy, ran the scan and removed all entries. Used the pc on and off for a few days. No issues. Gave the pc back... Within 2 days...it's back. Is there a better freeware scanner/remover for this. I'm at my wits end with this.

Or install Avast and do a boot time scan.

1. Boot in safemode

2. Empty ALL temp folders, including user temp folders, not just windows

3. Reset IE, checking the box to delete everything

4. Open regedit:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Delete any suspicious looking entries

Also delete anything in HKEY_CURRENT_USER\Software and HKEY_LOCAL_MACHINE\SOFTWARE that look malware related

Open MSCONFIG and disable anything that looks suspicious in there too

----------

Reboot in normal mode, and run a full scan with a fully updated malwarebytes

You have already scanned with spybot but do it again anyway

Another good thing is installing Avast Free, and do a "Boot Time Scan" this will be able to remove malware that can not be killed inside of windows

Download and run a scan with "Hijack This" remove any suspicious entries in there too

Scan a couple of times with all the above programs until they all return a clean result

If you still have a problem after all that, wipe > reinstall windows

What exactly would be considered suspicious? I'd assume they would label anything that would set off red flags..

Well just anything you don't recognise as being installed on the machine as a genuine app, a lot of malware will have registry keys with weird symbols, such as !"

Latest version is 2.04....It doesn't work properly with 64bit oses. It also doesn't dig as deep as otl.

Compare a hjt log with a otl log.

sample otl log

sample hjt log

http://www.techsuppo...down-14837.html

which do you think is more thorough and can help you better find the cause?

Ok, never used OTL, still HijackThis is a decent app, using both would be better than not using HJT, never had a problem with HJT and 64bit OSs though

read about hjt and 64 bit, while this isn't necessarily a problem people unfamiliar with it will go to disable critical processes and screw their computers up more. I don't recommend running this as a novice, nor do I recommend running it over the internet being that people can be tempted to try to fix it themselves causing more issues. bottom line, it doesn't work well with 64 bit oses and otl produces the similar findings as hjt with many more pieces to the os puzzle (more files, more reg entries, more points of infection, etc). Running otl with a good rootkit detection software, like gmer, will allow you, the tech, to actually find something useful and be able to repair the computer.

That being said, it may take a few hours to go through and verify a otl report.

Well that doesn't render HJT useless on 64bit systems, we're not looking for missing file entries, we're looking for malware entries, make no difference if HJT can't find 64bit files

And more to the point, I don't know many 64bit versions of malware

not exactly useful either. if it is not useful, it is useless IMO.

you could do what others said and waste your time, or do what will be the easiest. Download a 10 meg file mawarebytes.com from here (filehippo link) on to a usb key. Boot into safe mode, install, run a scan, let it remove it. Done. If you want to do it the hard way, follow the other posts above.

Secret....malware bytes doesn't remove everything. Their root kit detection piece is still in beta last time I checked. Malware bytes is not the end all be all.

I have been around a lot of malware, and I can tell you with 100% certainty that malware bytes doesn't remove all of it. Just a good portion. I run a min of three different removal utilities mwb being one of them when cleaning computers. Mwb isnt the first thing i run, it is the last. I do know its limitations.

after servicing a couple thousand machines over the last couple years , i have had a 100% success ratio with malwarebytes when scanning in safe mode. Could you give me an example of malware that it can't remove? I would like to download it and see for myself.

note: i LOVE getting new stuff to test virus removal techniques. being serious.

Pick any root kit. The Remote Desktop attack 6months ago it couldn't detect (MSE was the first that did). Had problems finding, file name was close to a windows file name and I kept overlooking it.

I have been doing manual virus removal since late 90s. I have thousands over you. Hell, the hospital I was working at had a whole site infection over 10000 computers and hundreds of servers. Nightmare.

Huh? How is it not useful ?

What do you have against HJT ? It works, what more do you want ?

Is it that hard to google root kit names, like I said pick one any one. Pull any one out of a google search. Malware bytes is 100% ineffective against any root kit. It doesn't have the scan engine for it, therefore it can't detect or repair against this type of infection. Google redirect is one.

Here you go read through and you will see that the user running malware bytes has no effect against it. http://www.bleepingcomputer.com/forums/topic434638.html

I don't like doing things twice and skimming through information I have been through before.

Surprised you could not give one from your own extensive experiences and instead saying Google one. I am having no luck finding an .exe for the google redirect to infect myself with. Google is full of solution links and no actual download links (of course and expected). Do you know where i can get the .exe file? Or maybe a website that does give the infection?

Yeah Malwarebytes doesn't get Rootkits at all, I use TDSSKiller for that.. Along with Malwarebytes and Combofix to clean the rest.
