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'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]

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. In addition, it runs significantly slower than I would like, and cannot play most videos at all--the sound plays fine, but the image just staggers and jumps. [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?

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.
Open source software is considered trustworthy because anyone can validate the source code and hold the developer accountable. Usually developers will also make compiled binaries available for convenience. How can we know that these binaries are compiled from the same source code the developer published, and not a malicious variant of it? [more inside]

I was browsing reddit on my Android tablet and had opened a number of tabs in the background in Chrome; I noticed that one of them had downloaded an .apk file (333s111.apk, the only other reference to which is here). I didn't run the .apk and deleted it straight away via the File Manager. I didn't see any evidence that it installed itself, or did anything malicious, and I don't have that option that allows non-Market apps to install themselves turned on. [more inside]

My computer was just infected with the JS/blacoleRef.Q trojan. Microsoft Security Essentials was able to flag and quarantine the infection and allow me to download and install the latest malware definitions, (mpam-fe.exe), disconnect from the web and do a full system scan. Another computer was used to go online and research JS/blacoleRef.Q. This trojan was described as not being removable by (most?) anti virus programs. The registry changes that were expected from this infection were not present. A change in a quarantined Firefox file located in my Application Data file had been removed. This system was infected when I clicked on a photograph while doing a Google Image search for plumbing fittings. How can I find if this trojan is still present and active in my system? How, if it is still active in the system, can it be removed? I am very uncomfortable about making changes in my registry. I am also uncomfortable with making random selections of malware removal tools on the web. Help!
