My Problem  I'm a Windows 7 user and to get it out of the way, Windows 7.exe is not a Windows 7 file. It's a smart virus that is using all my CPU.   What I've Tried  Every time I hit end process in a task manager, it comes back up and takes all my CPU again within seconds. I thought I could delete the file so I went to file location, but all I found was an empty file called windows 7. This file can't be found on My Computer. I then attempted to stop all services associated with Windows 7.exe, however when I went to services from the taskmanager, none of the current services were highlighted. When I disconnect from the internet, this process isn't able to start up.   My Question  I've run out of ideas on how to practically get rid of it and may have to clean install windows. I'm wondering if there is a less bothersome way to do this.
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.

I am looking at simple functions to be overloaded like    foo (int a)   foo (char b)   foo (float c , int d)   I think there is no straight forward way; I'm looking for workarounds if any exist.

Based on this question: , LVS may be the right solution for my problem.   But when I went to its homepage , I found that LVS has been updated since Nov, 2008. The world's moving fast, and I don't know if LVS was obsolete or not.  Is LVS standing still, or there're some better solutions to replace it?  Thank you so much. I am trying to prove that the set of irrational numbers $\mathbb{R} \setminus \mathbb{Q}$ is not an $F_{\sigma}$ set. Here's my attempt:  Assume that indeed $\mathbb{R} \setminus \mathbb{Q}$ is an $F_{\sigma}$ set. Then we may write it as a countable union of closed subsets $C_i$: $$ \mathbb{R} \setminus \mathbb{Q} = \bigcup_{i=1}^{\infty}  \ C_i $$ But $\text{int} ( \mathbb{R} \setminus \mathbb{Q}) = \emptyset$, so in fact each $C_i$ has empty interior as well. But then each $C_i$ is nowhere dense, hence $ \mathbb{R} \setminus \mathbb{Q} = \bigcup_{i=1}^{\infty}  \ C_i$ is thin. But we know $\mathbb{R} \setminus \mathbb{Q}$ is thick, a contradiction.  This seems a bit too simple. I looked this up online, and although I haven't found the solution anywhere, many times there is a hint: Use Baire's Theorem. Have I skipped an important step I should explain further or is Baire's Theorem used implicitly in my proof? Or is my proof wrong? Thanks.  EDIT: Thin and thick might not be the most standard terms so:  Thin = meager = 1st Baire category Installing Ubuntu on a single partition I’m trying to install Ubuntu 16.04 alongside with Windows 7. My HDD supports only 4 partitions. Three of the partitions are taken up by windows. The fourth one is labelled as free space.   Now, how do I make root, swap and home partitions? Should I format my free space as primary with EXT4 first (if so, what should be the mount point?) and then create logical partitions for root/Home/swap? How do I go about this?  Edit: I tried to use the automatic installation option for dual boot. However I got the error ubi partman exit code 141. Probably because it tried to create two separate partitions for root and swap.   $ sudo parted -l Model: ATA ST1000DM003-1CH1 (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Disk Flags:   Number  Start   End    Size   Type     File system  Flags  1      1049kB  106MB  105MB  primary  ntfs         boot  2      106MB   277GB  277GB  primary  ntfs  3      277GB   903GB  627GB  primary  ntfs Can “due to” and “because of ” be used interchangeably?

I've tried the following solutions, but nothing worked I'd like to estimate the correlation between:  An ordinal variable: subjects are asked to rate their preference for 6 types of fruit on a 1-5 scale (ranging from very disgusting to very tasty) On average subjects use only 3 points of the scale.  A continuous variable: the same subjects are asked to quickly identify these fruits, which results in an mean accuracy for the 6 fruits.   Is Spearman rho the best method to analyze these data and/or are there other good methods I could consider? asp.net mvc put controllers into a separate project I'm just learning asp.net mvc and I'm trying to figure out how to move my controllers into a separate project.  Typically when I have designed asp.net web apps before, I created one project for my models, another for my logic, and then there was the web.    Now that I'm learning asp.net mvc I was hoping to follow a similar pattern and put the models and controllers each into their own separate projects, and just leave the views/scripts/css in the web.  The models part was easy, but what I don't understand is how to make my controllers in a separate project be "found".  Also, I would like to know if this is advisable.  Thanks! I am stuck with the proof of below expression;  "If F is an infinite field, then no infinite subgroup of F* (the multiplicative group of F) is cyclic."  anyone can help? Range of values of skewness and kurtosis for normal distribution I want to know that what is the range of the values of skewness and kurtosis for which the data is considered to be normally distributed.   I have read many arguments and mostly I got mixed up answers. Some says for skewness $(-1,1)$ and $(-2,2)$ for kurtosis is an acceptable range for being normally distributed. Some says $(-1.96,1.96)$ for skewness is an acceptable range. I found a detailed discussion here:  regarding this issue. But I couldn't find any decisive statement.   What is the basis for deciding such an interval? Is this a subjective choice? Or is there any mathematical explanation behind these intervals? Holomorphic function has at most countably zeros Let $f$ be holomorphic in a domain $U$, then $f$ has at most countably zeros.  How can I prove this statement? I have seen it in Sheng Gong  explicitly, but without any indications. "Naturally occurring" non-Hausdorff spaces? It is not difficult for a beginning point-set topology student to cook up an example of a non-Hausdorff space; perhaps the simplest example is the line with two origins. It is impossible to separate the two origins with disjoint open sets. It is also easy for a beginning algebraic geometry student to give a less artificial example of a non-Hausdorff space: the Zariski topology on affine $n$-space over an infinite field $k$, $\mathbf{A}_{k}^{n}$, is not Hausdorff, due to the fact that polynomials are determined by their local behavior. Open sets here are in fact dense. I am interested in examples of the latter form. The Zariski topology on $\mathbf{A}_{k}^{n}$ exists as a tool in its own right, and happens to be non-Hausdorff. As far as I'm aware, the line with two origins doesn't serve this purpose. What are some non-Hausdorff topological spaces that aren't merely pathological curiosities?
