The news stories on Friday's attack on Dyn noted that devices from the "internet of things" has been infected by malware which was conscripting them to send requests to the DNS. Is there anyway I could know if devices which I own were infected? If they were is there anything I could do about it?

I am holding my CEO's credit card in my hand and cannot leave work without purchasing either Norton or McAfee today (thanks to our sales guy who keeps getting malware on his computer). Running a Lenovo Yoga 3 Pro-1370 with Windows 10 and Windows Defender, however, they are not convinced this is sufficient and are forcing me to buy/install one or the other today. Help? [more inside]

I have an HTC One M8 (on Verizon), and it's exhibiting a number of strange problems. Over time, my phone has gotten slower and slower, to the point of occasionally becoming completely unresponsive. It's also developed a habit of spontaneously rebooting itself. Performing a factory reset or upgrading the OS seems to fix both of these problems for about a month, before they start creeping back. More details inside. I'm primarily interested in tracking down why this is happening, and identifying the root cause so I can make it stop forever. Technical answers/explanations are welcome.

An odd error message appeared on the navigation screen in my 2013 Hyundai Genesis Coupe yesterday that said something about not connecting to mrfish.exe.

I don't do a lot of random downloading, and surf with NoScript, so I'm not too concerned about an always-on solution. I'd like to be able to scan odd bits and pieces, though. I used to use ClamXAV. That's gone to a paid product, which I'm 100% okay with paying for if it's still the best option. What else should I be looking at?

I have several websites that are hosted through Network Solutions. Since April, I've noticed more and more malware that is blocking my access to my websites. Only the sites on this provider are infected. Until this year (and for the 8 previous years on one of the three sites), I've never had any malware or infections. The provider offered me a new service where they monitor my sites and tell me how much malware is infecting them. I already know they are infected and inaccessible. They also say they can disinfect my sites for an additional $6.99/mo. Isn't it their responsibility to keep malware off their server that can infect account holder sites? Is this a legitimate ask by them?

I've very recently (ie yesterday) got myself a brand new desktop PC!

I've got a 4 year old Windows desktop that I use for very few things: Metafilter (using either Chrome or Firefox), email (Thunderbird), Word, and NVivo (a qualitative analysis software). I also play Steam games on the machine occasionally. I went on vacation, and when I came back, the computer was - for lack of a better term - completely messed up. [more inside]
Specifically, it's a mplayer virus. It has infected Google Chrome and Firefox, and is showing infuriating pop-up ads and frequently redirecting the browser to ad-like pages.

I am incredibly geeky (though I certainly know geeks who are moreso) and somewhat hackerish, been running my household WiFi and Wired network to dozens of devices for several years and everything was fine until my Mom's new housesitter brought a laptop into the network that was profoundly infected with various malware. I THINK the malware issue is still contained to his laptop but household broadband utilization went from 200 - 300 GB per month in January/February to more than 650 GB in March and we're still racking up 10-12 GB per day in April. I need help with what to do without alienating anyone and what I can do to support the housesitter while he also works locally on his computer to remove the malware. Brainstorming, new techniques, anything like that would be helpful. [more inside]

My HTC One Android phone has somehow become infected with a Facebook app again. I want to delete it permanently, completely and forever. It wont let me, I've checked the forums and googled around. When I drag the icon into 'remove' or 'un-intsall ' it just wont. It doesnt show up in my list of Apps in the App manager menu... its like voodoo...Gah! Is there a way or is Facebook like forever, like Orwell's canonical Boot?
I have a Samsung NC20 laptop that I bought 4 or 5 years ago. It runs Windows XP and has some sort of malware, IRP Hook, that AVG has found but cannot remove.

Every once in a while I'm called upon to help a family member or coworker who has gotten a virus or malware on their computer. I generally just have the virus/malware program get rid of the offending files using its default method, and almost always when I run another scan it comes up clean. But when I research the specific files to find out what they do, I find posts detailing multi-step processes using multiple programs to completely remove the infection. So I have to wonder, is letting the virus/malware program that detects the bad files take care of them really enough to secure the computer system, presuming that subsequent scans come up clean?

Today, my bank's fraud detection department gave me a call - apparently, somebody had attempted to use my debit card for a purchase in Colombia. I live in London, UK. This is an annoyance, but it's particularly worrying because something similar happened less than two months ago - they called me up and said that although my card hadn't been used, they had information that it may be compromised. The card that was used in Colombia today was the replacement, which I've had for only a few weeks. My money is safe and my card has been cancelled (again). But my main concern is HOW this has happened - keylogger? Dubious, but legit-seeming site? Compromised wifi? And how do I keep myself safe in future? [more inside]

A few minutes ago, my macbook pro (OSX 10.6.8) played what I think was the Skype incoming call chime. I didn't think Skype was running, and as I was Cmd-Tabbing through applications to see if I'd accidentally left Skype turned on, the webcam light briefly flashed. Skype wasn't running, but I double-checked by starting Activity Monitor, and didn't see any processes with Skype in the name. I'm not totally sure it was the skype chime, because I don't use skype often. I do have google chat running in gmail with video chat enabled, but there were no visible notifications in the gmail window. I suppose it could've been a deceptive flash ad in a browser tab, but it's the webcam light that creeps me out. Any ideas what might have happened? Should I find a malware scanner? Is that even a thing? The last ask.metafilter match for "osx malware" is almost 2 years old.
