Ensign Expendable posted:Most of the time Virut digs in so deep that purging all infected files renders the system unusable. You pretty much have to reinstall after that anyway. It's really fun when you run ComboFix on a particulary bad infection and you start seeing things like: *Scanned Notepad.exe - File Infected - Action Taken: Deleted *Scanned IExplore.exe - File Infected - Action Taken: Deleted *Scanned Freecell.exe - File Infected - Action Taken: Deleted *Scanned ccSvcHst.exe - File Infected - Action Taken: Deleted *Scanned Explorer.exe - File Infected - Action Taken: Deleted Whoops! Powerful program but you really have to be careful. Oddhair, if you catch it early enough and it hasn't really spread, you're probably fine. My opinion though is that I can never trust that computer again. Flatten and reinstall is the option for ALL virus problems as far as I'm concerned.

Oddhair posted:I had posted earlier in the thread about finding a computer which had files infected with Virut, but not many. I scanned offline on a different, plain-Jane XP machine I keep off my network just for that kind of thing, and cleaned it up pretty well, and then did a repair install. It seems fine, even now months later. I keep thinking there's some glaring hole in my knowledge that I'm overlooking, like the blind spot in each eye. I should be good, though right? Virut is easy to remove as long as it's not active while you're doing it, and as long as you don't care about system files being slightly different compared to the original versions when it's all done.

You know how in the fine print household cleaners say you need to soak it on the surface for 30 seconds to really kill bacteria? Well, if you haven't done a 3-pass wipe it's possible that your computer could become breeding ground for format-resistant superviruses!

CraigK posted:I'm just waiting for viruses that can survive a format c:\ *.* /y. Mebroot/Sinowal already does. It loads its driver through an infected MBR and the driver itself is stored beyond the end of the last partition on the drive. Some versions also have a nasty bug in their stealthing code that will crash a lot of raw disk reading applications (such as hex editors) if they try to read the first few sectors of the disk.

Jetsetlemming posted:Would this survive a format of the entire hard drive? When I installed Ubuntu last week I had it remove the ntfs partition and create a new ext4 one over it, that wouldn't leave anything at all on the hard drive, right? Assuming you were infected before (which I assume you aren't but hypothetically...): If you installed Ubuntu then the Ubuntu installer would have overwritten the MBR with Grub. However, if you set up Grub to dual-boot Windows it might have created a copy of the infected Windows MBR somewhere (not sure if the Ubuntu installer supports this or not). Also, assuming your partitions were the same size, the virus code at the end of the disk is probably untouched as it's not actually inside the NTFS partition -- it's just after it. But it doesn't load on anything except Windows anyway so you don't really need to care.

Tapedump posted:How effective would fixmbr be on Sinowal? If you can get into the recovery console it works, but in a lot of cases it seems that the recovery console hangs while loading, even if you boot from the Windows install CD. Bootable linux and dd is the easiest solution, as the original MBR is saved just past the end of the last partition (directly before the Sinowal driver module) and if you copy it back everything should be fine.

I'm trying to help my boyfriend get rid of a virus on his computer. I was checking QCS since we're thinking he got it from an ad, possibly here or facebook, and it seems like a few other people had similar issues and had a few suggestions, and someone suggested that I come here to ask. One problem is that we are currently 4 hours away, so I need to relay this stuff over phone or text message and neither of us knows a lot about computers. It is not letting him run his virus check in regular Windows XP, so he went into Safe Mode and he said it would only check command lines, but all it came up with was a few .dat files. I've never had a virus that I couldn't just clear up by running my antivirus software. He has a free version of Symantec we got from school. I've heard AVG is pretty good, and possibly better, so I guess getting that once this clears up. I'm sorry that I can't explain this too well, but please provide any suggestions you can and I will try to answer any questions. Thanks.

Yeah, a bunch of people are getting these. I've been hit twice so far, but Avast! intercepted it both times. From what I saw, it looked like a Javascript thing that tried to start up Acrobat Reader. Avast killed it before it finished, so all I got was the Visual Studio debugger message about it. Anyway, Symantec sucks. Use MalwareBytes AntiMalware to clean up most of it and then scan with Avast to clean up the remains, if any. Both of those are free, and if the malware won't let you run them, just rename the executable.

He renamed the mbam file in the program files folder and says that it still won't open and that it pops up and error saying that the file is infected. When he tried to open it in Safe Mode, he got run time error. What could fix this? Edit: He's trying to get CCleaner to work, since it seems like runtime errors mean you might need a registry cleaner but that's not running either.

If you're desperate, get ComboFix and run that. It will ruthlessly exterminate every last remnant of that virus. Unfortunately if you're not careful or if the infection is too deep it will take down a lot of vital system files as well.

Combofix is such an amazing tool. I really don't know where i would be without it. I am almost at the point now if combofix and a virus scan wont 100% fix it ill just flatten and reinstall the machine. It's faster that way anyhow. Also why are people still using Avast! (?) Isn't MSE overall a much better antivirus? Is it because people still roll their eyes when they think 'Microsoft' and 'security?' MSE scores very well on those AV comparative websites and seems to perform pretty much just as well as any of the paid AV applications. MSE is great, it's like the best product ever for non-computer savvy people. It just chills in the tray and wont bug the user unless something is wrong. And unlike other free AV programs it wont have popup banners or crappy interfaces to confuse a novice user. I say the only thing to knock it on is that it uses up a lot of ram. I think around 50 MB. Oh well ram is a cheap as dirt these days and even a new middle of the line HP comes with 6gb of ram.

So my (Windows XP) laptop is a bit of a clunker and is, when shutting down, confronted with quite a few "End Now/Cancel" windows. This time, however, a window popped up for a certain "n.exe". Curious, I entered this file name into Google Search and unsurprisingly it turns up a definition for a virus/trojan file. I've run multiple virus scans (Norton Antivirus) since then, all of which have turned up nothing. Also, earlier this week, Auto-Protect caught, quarantined, and deleted a Trojan Downloader file. Could these two have any relation, and if so, why am I dealing with a trojan file that seemingly has already been deleted?

Avira just released an Antivir update that flags uTorrent in all forms, including the installer directly from their website, as a trojan called "TR/Ag.289584.AA". http://forum.avira.com/wbb/index.php?page=Thread&postID=883032&s=b3a3a06a05f4a6f1733fb8d964720f382c65d059 First time I've heard Antivir bug me about anything at all since I installed it.

When he tried to open it in Safe Mode, he got run time error. What could fix this? On XP go to C:\Documents and Settings\{your name}\Local Settings\Application Data if you can't see it... it's hidden so enable hidden files/folders. Look for a folder with a randomly generated sequence of letters (i.e. gkhsds) it may be closer to english, or look like something real. The tipoff is that the folder will have one .exe file in it. Open Run and type 'tskill (name of exe)'. tskill will try to kill the process before the process kills tskill so you might need to do it a few times before it takes. Once that process dies it will allow you to clean with malwarebytes, etc. I have to do this all the time to fix infected computers after-hours when I can't be there physically to reboot into safe mode or do other tricks.

You can tell people a thousand times that they have an antivirus, give them all the best tools to scan their systems, but nope, when it comes down to it, that little gif is still blinking... YOU HAVE 59 INFECTED FILES! INSTALL RETARD RAPER PRO TO REMOVE THEM NOW BEFORE ALL OF YOUR PERSONAL INFORMATION IS STOLEN!!! I really have had customers bring back systems, telling me "it has a virus", the knowledge of which comes from one of these antivirii. We usually try to explain why they're stupid before telling them to get out.
