My home server (aging HP Proliant MicroServer, Windows 7 x64) has acquired some Malware from Hell. Turned up in one of those dodgy installers that wraps a legitimate installer in another package, and installs all sorts of nefarious software on your system.  It has proved intractable. Three processes are now running constantly on my machine, using CPU and doing goodness knows what.   And they're unkillable. I can't kill the processes, all I get is an "Access is denied".  The processes are called:   svnlgau.exe  iaawlnv.exe  igfxmtc.exe   I've traced the three executables to these folders:  C:\Users\&lt;user&gt;\AppData\Local\iaawlnv C:\Users\&lt;user&gt;\AppData\Local\igfxmtc C:\Users\&lt;user&gt;\AppData\Local\rtnpeku   All of which are owned by some unknown account and are inaccessible.  Things I've tried:   Changing the owner of the folders to the Administrator Using "Unlocker" on the directories to take possession of them Booting in safe mode as an administrator, killing the processes and deleting the directories Scanning with Microsoft Security Essentials (which can't access the folder either) Scanning with MalwareBytes Scanning with Windows Malicious Software Removal Tool (MSRT) Killing the processes with Kaspersky Task Killer   Short of rebuilding the machine, which would take days, is there anything else I can try?
What should I do if my Windows computer seems to be infected with a virus or malware?  What are the symptoms of an infection? What should I do after noticing an infection? What can I do to get rid of it? how to prevent from infection by malware?   This question comes up frequently, and the suggested solutions are usually the same. This community wiki is an attempt to serve as the definitive, most comprehensive answer possible. Feel free to add your contributions via edits.
How can you smooth the edge between two materials? Right place to ask a "discussion" question (I'm setting up a blog, what should....) How to create a scope? I'd like to create a custom scope that searches and returns results from an online source for personal use.  Is this possible? And if so, how? I wonder  whether there is a function $f\colon\Bbb R\to\Bbb R$ with the folowing characteristic?   for every two real numbers $\alpha,\beta,\alpha\lt\beta$,  $$\{f(x):x\in(\alpha,\beta)\}=\Bbb R$$   I can't  say such a function does not exist, neither can I construct a example  Thanks a lot! I have a MicroSD card in a USB adapter (which plugs into a USB port on my machine, and acts like a USB flash drive). I was using Unetbootin to make this a bootable USB flash drive with Kubuntu. But I needed to cancel while it was working. So I killed the Unetbootin process from the console.  Since then, I can't format the MicroSD or delete the folder that Kubuntu made. I have also tried mkdosfs, with no success. I can't mount the drive anymore either? What can I do to make this drive usable again?  Trying to create a new partition table in GParted, as described in Eliah Kagan's answer, does not work. It fails with the error message "imposible crear tabla de particiones" ("unable to create a partition table"). Where in the DNS process are NS records used? I register a new domain, mynewdomain.com, at a hosting company.   In the advanced DNS settings there is an A record which maps mynewdomain.com to a ip address.  In my webhost control panel, it shows me the nameservers for the domain: ns1.mywebhost.net &amp; ns2.mywebhost.net  When I type in mynewdomain.com into a browser and hit enter I believe the following happens.   ISP resolver searches "." nameserver ISP resolver then told to search ".com" nameserver instead. ISP resolver finds mynewdomain.com, and searches the zone file to get the A record.     So my question is, where does my webhost's nameservers come into play? I believe the flaw in my logic comes from the fact that my zone file (in which the A record is kept) is stored on ns1.mywebhost.net). But if that is the case, how does my ISP resolver know to look here? (because I didn't type this into my address bar) Office 2016 Advanced Setup Assume that a person (not me, I only hold a single citizenship :) has a double citizenship in countries such as the US, Singapore, Australia, Japan, etc, which are eligible for 90/180 visa-free stays in the Schengen area. Could they officially remain in the Schengen area indefinitely by taking a trip to (say) the UK every 89 days? Almost all passports I have seen have a place of birth field on them. For instance, on the US Passport,    Is there a specific reason to this? How do I make Div Container 100% width only on homepage of site? I have an object with two solidify modifiers added, but the modifiers are not visible in the view pane. How can I see the applied modifiers. This is in Blender 2.91 Is there any way to view which applications are accessing the Internet on Mac OS X? I think I remember a command line utility that did this, but I can't remember what it's called and a few Google searches turn up nothing. Upload files with HTTPWebrequest (multipart/form-data) I have often read that using RSA for encrypting bigger size plaintext is not good solution.  What I understand is that using RSA encrytion is best for small plaintext and most effective if it is smaller than 'bit size' of RSA. For instance, if I use RSA with a 2048 bit size then the plaintext that I can encrypt must be smaller than 256 bytes.  Is this true? What happens if the plaintext is bigger than 256 bytes? Why is there a problem with larger plaintext when performing RSA encryption? Kepler problem in time: how do two gravitationally attracted particles move? Two particles with initial positions and velocities $r_1,v_1$ and $r_2,v_2$ are interacting by the inverse square law (with G=1), so that  $$ {d^2r_1\over dt^2} = - { m_2(r_1-r_2)\over |r_1-r_2|^3} $$ $$ {d^2r_2\over dt^2} = - { m_1(r_2-r_1)\over |r_1-r_2|^3} $$  (the inverse square law along the line of separation). What is the complete solution of these differential equations? What is the position of the two objects as a function of time?  After reading a lot on Wikipedia, I've come to the definition of center of mass and relative coordinates:   $$R(t) ~=~ \frac{m_1 r_1 + m_2 r_2}{m_1+m_2}$$  $$\ddot{r}(t) r(t)^2 ~=~ (m_1+m_2)G$$  Where $R$ is the center of mass, and $r$ is the displacement between the particles... Is this correct? How do I proceed to solve the differential equation? What is the real answer to the Birthday question? "How large must a class be to make the probability of finding two people with the same birthday at least 50%?"  I have 360 friends on facebook, and, as expected, the distribution of their birthdays is not uniform at all.  I have one day with that has 9 friends with the same birthday. (9 months after big holidays and valentines day seem to be big ones, lol..)  So, given that some days are more likely for a birthday, I'm assuming the number of 23 is an upperbound.

Here's the flair:    However, I don't have 28k rep. According to chat, I have 19.7k.  Note: I know about the combined flair - I've had this in my profile for at least a year. It had been showing me the same as in chat, now it isn't.   What is going on here?  Edit: I'm reporting a bug here, that the combined flair is not showing the correct number, as it has in the past. Why is Euler's Totient function always even?
