Today, I was on my Windows laptop and a command prompt window opened, which changed from red text to green text really quickly, almost too quickly to catch. I wiped and re-installed Windows, and now, the same command prompt popped up again! Screenshot: here. Is my computer infected? How can this be with a full wipe and re-install?
I need to put the fear of God into some foolish, negligent users. I'm looking for examples of organizations that were hit with some kind of horrible malware (like CryptoLocker) or had sensitive data stolen -- all because of a really stupid action by an employee. [more inside]
My dad just called me in a panic. His iMac (running El Capital or Yosemite) gave him a scammy looking error message. Need some help figuring out what's going on and how to fix it. [more inside]
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 was one of the 6,000 unlucky souls to download the KeRanger ransomware virus for Mac. It seems that I caught it after it started to encrypt my files, but before it encrypted all of them. Am I still at risk? Next steps? [more inside]
I've recently been getting an email message which appears to be dated 12/31/69, but has "no sender," "no subject," and "no content." The first couple of times I just deleted it, but now it pops back in almost simultaneously with the deletion, so that my mail icon chronically shows at least 1 unread message. [more inside]

You are not my doctor. I have a doctor who I will see for the third time later today. This has been going on for four weeks now without much visible improvement. I really need it to improve because right now I can't run or hike and I have a bike trip coming up at Christmas and a half marathon in January. I already missed a race last weekend. Any ideas for what worked for a similar stubborn cough? [more inside]

I'm travelling to help an elderly relative (in pain, sciatica, on pain meds) who is 83 and fuzzing mentally. She has been pretty good with computers for years, but is having trouble maintaining her PC. I thought an iPhone would be easier but she hasn't taken to it. So I'm looking for some kind of ultra simple phone (few features, big buttons, I doubt she'll text), and a replacement computer. [more inside]
So I have some malware on my PC that appears to be trying to connect to all the domains in this list (or a very similar list)

I may be able to pick up an obscure but useful domain name soon. However, it was once a domain used for command-and-control systems for a well-known trojan that spread throughout the Internet. For the last five years, it's been held by a security/enforcement group that took it over. [more inside]

I've very recently (ie yesterday) got myself a brand new desktop PC! I would really like your advice on the best ways to keep it running at its best, protected from the nasty things that lurk on the internet (virii, malware, spyware etc) and set up to get the most out of our blossoming relationship... The machine runs on Windows 8. [more inside]
I'm looking for examples of contagious infectious diseases for which there is no known cure (and which do not clear on their own) but which are non-fatal (or can be rendered so with known treatment). So basically, a disease where once you catch it you've got it forever, but it probably won't kill you, at least in the short term. Examples: Herpes Simplex, HIV. [more inside]
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. Who knows what else it's doing/stealing/collecting. This may be what I deserve for trying to download some TV, but I need to get rid of it. Running Mac OSX 10.8.5. [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?

Setting up a new computer for my mother and stepfather I've accidentally installed a virus. After three hours of slogging through getting a new computer set up for them (why would we write down any of our passwords, the old now dead computer had them all saved) I tired and not paying attention downloaded Firefox for them. Problem: It wasn't from Mozilla, didn't realize until afterward that it was from something called ez-download. Internet says this is a Trojan. I've turned off the wifi and have windows defender running a scan. There is nothing on this computer from a software standpoint that needs to be saved. Computer didn't come with a windows8 disc but rather a partioned drive. If I run a reset to factory will that be easiest? Will it work? Halp!
Microsoft Security Essentials Missing From System Tray. [more inside]
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?

Details aren't necessary except for sometimes when I have to sort clothes to be cleaned, I run into other people's garments that are soiled in some way. What's the likelihood that I am going to pick up anything unwanted as far as blood/fluid borne disease or any other nasties? My hands do not have any obvious sores or anything like that. This doesn't happen often and I thought I would ask here before I get too obsessive with my hand washing or badgering my doctor. Yes, I realize you may not be a doctor. Thanks in advance.
Father-in-law's got hacked/virus. He's been sending out one-link emails to all his contacts. I went into his webmail for him and changed his password to something a little more secure - but his contacts aren't stored there (and neither's his sent mail), so it's got to be his machine, right? But I've done the full Deezil and found absolutely nothing. Not a sausage. So, where can this little nasty be hiding? He's running 64-bit Windows 7 with an up-to-date Norton AV. His mail client is windows Live Mail.
I've started getting emails "from" people in my contacts list. The email is from their name, but with an email address that is not theirs and is different each time. I have an address with a local internet provider, not gmail or yahoo. Do I have a virus my antivirus hasn't caught? How can I fix it?

This may end up in a story, it may not... But this occurred to me the other day. We all learned in school that viruses need a host, bacteria do not. Therefore if we all voluntarily quarantined ourselves for two weeks, how many potential viruses could we wipe out? [more inside]
I assume the tools have changed in the past 5 years or so, despite Windows' better security, but back in my day it was Avira, Symantec and CCleaner.

Several weeks ago, I saw an intriguing quote about how if something spreads person to person, it's a virus or a bacteria, but if it's everywhere at once, it's a meme. I want to include the quote in my intro to epidemiology course but can't find it. Help? [more inside]

Someone I was in contact with on Christmas has just been diagnosed with shingles. There was skin to skin contact, although I didn't notice any sores (but I wasn't looking for them). I'm concerned that I could transmit the virus to others - particularly some young children, elderly, and otherwise immunocompromised people I would be seeing at another family gathering tomorrow. Should I quarantine myself for a bit? [more inside]
