You don't really need to do anything more fancy than reinstalling Windows (using the option that formats the hard drive) to get rid of them.

I've read around a lot and seems that this is the only way to deal with redirect malware, I actually came across a computer I spent HOURS on and finally reformatted it. Is there nothing that can be done to clean that particular malware off?

Speaking of Viruses, holy loving gently caress, ThinkPoint was a goddamn epidemic today. 50% of our calls were to handle it.

Fucker pops up in normal, safe modes.

You can bypass it by throwing the horns and killing the process tree on hotfix.exe, but generally the easiest way is to system restore, then mop out the remainders.

That said, when I see MyWebSearch on the system, I can assume it's got e-herpes.
I had a computer come in like this the other day. Couldn't get it to recognize a flash drive so we could get MWB and it's update to scan. Sadly there were no system restores on this computer.

I think we scanned it externally, but dunno if the other guy got anything off by doing that. If that doesn't work, I'm going to manually place the MWB program on the HDD somewhere through another computer then run it that way.

Okay, I just came across a new rogue antivirus. Typical style name of "Internet Security Suite". I'm having a problem getting rid of the final bits of it. I've run MalwareBytes, attempted a manual removal and it still lingers. I usually see it when I run ComboFix and it tells me to turn off Antiviruses (MSE and this one).

The other things is I can't tell if it's blocking my Wireless. I can hook up a hardline and it works just fine. I can get the wireless to connect, but it's as if it's not.

Edit: The wireless isn't pulling an IP correctly.

Have you done anything towards cleaning out autoruns? (Hijackthis, Autoruns, possibly using a BartPE disk? (I've had success with the minixp on Hiren's.))

If Combofix can't get rid of it, I would be leaning towards a reimage. Have you run Combofix in safe mode? Have you run any standalone rootkit scanners? Have you booted to recovery console (from a boot disk, not onboard) and run a fixmbr?

Regarding the wireless, do you have any other wireless devices? Do you have access to any other wireless access point? When you say not pulling an IP correctly, what do you mean? [No IP, wrong IP, 169.254.*.* IP, correct IP but bogus gateway or DNS information?] Have you tried turning off DHCP and hardcoding an IP just to test?

Wireless was fine, someone changed the password and didn't tell me. Ironically it didn't kick the password, just showed limited connectivity.

I'll rerun combofix in Safe mode again, then try autoruns. I'm trying to get away from formatting this computer as it has a lot of programs on it.

Well sure, but that's hardly what I'd consider a long-term fix. I'm using Microsoft's backup solution with Microsoft's antivirus solution on Microsoft's operating system; surely they could have it stop the service manually or do whatever is necessary to make this work without manual intervention.

That may be some leftover retardation from Vista. I'm running 7, do backups once a week and have never had a problem. I'll test on a laptop at work and see if it's vista specific or just some weird error you're having.

Not sure where to put this, it might as well be a virus but:

Has anyone noticed since an adobe update yesterday people aren't getting on the internet? I've had multiple customers complain about this, haven't seen anything else about it. Safe mode gets on fine, but I can't do any real testing (ISP restrictions on support) to see if removing flash/adobe horseshit fixes it or not.

Edit: now I'm getting wind that it's a windows security update for 7/vista.

I sandbox my browser and I've not had a single virus that couldn't be removed by right clicking "end process" in my taskbar. To that end, I have removed resident A/V from my system as it's nothing more than a resource hog (and virustotal is the best on-demand for anything suspicious anyway).

I have literally no idea why people ever, ever trust a browser to interact with their base OS, or to that end, need it to.

e: if we're talking about offering tech support to others, then anything that hooks itself in and requires indepth cleaning is pretty much "reinstall OS, fix everything"

I think I generally do MalwareBytes, Combofix and MSE. If those three can't get it, I generally just format and be done with it.

I've had to explain that concept to multiple people, most of them were rather difficult to convince. If you get caught with child porn, they aren't going to let you off the hook for $200.

I pose this question: "Do you think the FBI would take a bribe to let you go, or burst down your door and arrest you for child porn?"

Then remind them that child porn is a really drat serious offense, not a misdemeanor in any way.

The best thing I heard about this virus though was a new story on my morning radio station. Dude was caught dumping child porn into a dumpster outside his apartment building. Why was he dumping it? He got the FBI virus, and he got scared.

I would have done CCleaner first, just so MWB doesn't take as long. Regardless, MWB should clean most of it, Microsoft Security Essentials should be a good second, if anything lingers try combofix and TDSSkiller, if that doesn't work, back up and format the computer.

My uncle had one of them and kept trying to get me to install stuff to it. I remember it being very convincing at first glance.

Okay, so this is computer #2 I've seen with this now. It's not a sudden hiding of all files, but the first computer (the one mentioned above) is a windows 8.1 computer, and her files and start menu (The Metro) all disappeared, so did all her programs. I just had another computer today at another client's whose shortcuts were slowly going away, and now her programs are just magically disappearing.

MSE, Malwarebytes, Combofix, Superanti Spyware are all coming up with nothing. Has anyone seen anything like this?

I've seen this plenty of times, pretty harmless unless there's a new more horrible version out. I can't remember what causes it, but combofix should take care of it. afterwards you can just change the attributes on the user folders to unhide the files - or there's this : http://www.bleepingcomputer.com/download/unhide/

edit : hit it with adwcleaner too for good measure

So it's doing more than an +h on the file attributes? That's probably why I'm missing it. I'll run that to see what happens.

If something like that isn't working and it's still behaving erratically, it kind of is. The alternative is spending hours to days manually removing crap and finding you still haven't dug it all out. In terms of a time sense, flattening it and reinstalling is sometimes the best way.

Did the person say they were emailing you an "Adobe Invoice" with macros in word for some stupid reason?

It's almost certainly a virus unless they created the doc themselves. There's no reason for an invoice like that to have macros enabled, most invoices are created and saved and have all the data within them. Kaspersky probably didn't catch it as the virus isn't there... yet.

Does anyone know if there is a way to remove Avast externally? Their rescue disk only does scans, and I'm pretty sure that is what is stopping this computer from booting.

Neither mode will boot. It will lock up once it gets to the user selection screen on normal, and on safe mode it locks up at aswRvrt.sys, and everything I've seen from googling shows it's an avast issue.

Yeah, I would do any bootable media (Linux, whatever). If you have an External HDD enclosure (I got one off of newegg for $15 or some such) you can hook it up to an external computer.

Another way to test is just boot it up and see how it's acting. I've had people claim viruses only to have minor crap and a lot of bloatware where they just installed whatever (and somehow avoided all the really bad crap).

Does anyone know if Fiddler is used in some types of malware? Someone at a remote office was complaining about getting certificate errors when browsing the web and I found Fiddler certs installed on the computer. The office is about an hour away so for now I had them pull the network cable.

The thing is we've been having some, uh, issues at this location and I'm not sure if it was installed intentionally by someone on site or it's just some malware.

I've found that 99% of certificate errors are due to bad date/time on the computer. If it is this fiddler, it sounds like someone was trying to self-diagnose something.
