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 purchased some software recently from a company txf.express designed to help create an 8949 form for stock trades. It seemed that it was improperly calculating a few numbers, and upon my questioning the software creator asked for my trading history to review the data and look for errors. He then sent me a .piz file and asked that I rename it to a .zip file and open it for a properly functioning program. My limited understanding is that " if you receive a piz file in an email and you are not familiar with the person who is sending it or are unsure of why they are sending it, do not change it to a zip file and try opening it. This could result in infecting your system with a computer virus." Are their legitimate reasons why he should be sending a piz file and asking me to rename it?

So...I'm thinking my Mac has a virus. I have a Mac OS X 10.5.8. I keep running out of hard drive space and deleting files constantly, so I got Disk Inventory X to see where my space is.
