How do you remove a downloader Trojan virus in a 322dm3d.dll system file?
The dll file could actually be the cause of you getting the downloader virus. First focus on deleting the dll file and then you can run a virus program to eliminate any other viruses on your computer. First find out what processes that dll file has attached itself to. Go to run and enter procexp. When that pops up go to find dll or handle and enter your dll file name. It will specify which processes it has attached itself. If it's not a vital process then you can kill the process and subsequently delete that dll file. If it's attached to the winlogon.exe or explorer processes then here are a few more steps. Right click on each process seperately and go to properties. Under threads you will need to right click and kill each instance of the dll. You will also need to do this with any handles listed. I had to suspend the winlogon handle. Then you should be able to delete that dll. If it's protected and you can't delete it. Move the file to another folder... I moved it to a new folder in My Documents. Then reboot and you should be able to delete that file. Good luck...

Here are opinions and answers from contributors:
- I ran Grisoft AVG(Free) and it detected the crypter.E virus but could not remove it. I checked the test detail which listed the associated file"mousedrv.exe" located in C:/Windows/System32. I could not delete it because it was running, so I opened Task Mgr,clicked on processes tab and found the file. I ended it with Task Mgr "end" command then went to the System32 folder and was able to delete mousedrv.exe. However when I restarted my computer,a message appeared saying mousedrv could not be run from the registry. Using regedit, I found several run entries in the registry and deleted them. Restarted my computer again with no messages and ran Grisoft AVG again which did not detect a virus.
- I went on avg free edition and it didn't locate it but adaware pro did seek it out and then deleted it but then when I rebooted the PC it came back so I went on hard disk and then found it under the name of program 4,and then it wouldn't delete so I run a spybot on the actual program and it found 419 viruses on the program and then it enabled all the viruses open so I had to boot the PC up in safe mode then the files were able to be deleted, so boot up in safe mode and then delete the files.

How can you hack your girlfriends webcam?
1,000,000+ lines of code. Hacking is very, very, very hard. It's not at all like the movies, where you just type some thing like "hack <nameofcomputer> trojan.exe". In real life, you first need to penetrate the firewall, then gain admin control, either by tricking the user into giving your program admin control, or backdoor programs. Both are extremely difficult, because on one you have to fake a certificate, and on the other, you have to find a loophole left in the programming, which both apple and microsoft are very good at covering.

How can you get all your viruses off your computer?
Well it depends which one or more viruses have infected your computer. Most viruses can be removed without a hitch using a popular antivirus software like AVG. First run a complete scan of your entire computer. Most people have about a hundred thousands files stored on their computer. Therefore, the scan will most likely take about two hours to complete so don't get impatient or worry. After the scan is completed AVG will display the files that they have found to be infected and the name of the virus or other malware. Do what AVG tells you to and if it says restart your computer don't wait do it. Any questions post on my message board.

How do you do a virus check on your computer?
Your virus protection is listed in the installed programs list, and should also have an icon on the desktop for Windows, or an entry on the list generated by clicking the Start button at lower left. If no virus protection is installed, you may be prompted to start either Windows Defender or Microsoft Security Essentials (both are free for all Windows PCs). There is also anti-malware in the Action Center for Windows 7 and Windows 8.
How can you improve my CPU usage percentage?
The question is not how to lower cpu usage but to either use less cpu (close background processes) or to smooth it out (I cannot find a way to do that no matter how hard i search). I find that it is not always the amount of cpu usage that is the problem but the way it is used. Windows has many pointless services built into every PC that runs it and they are all automatically set to run (such as wmpnetwork, etc.) if you want the best out of your computer i recommend following theese steps:
1. download a registry cleaner (I use CCleaner)
2. clean all temporary files and defrag, obviously :P.
3. disable unused appearance and ui features (you should know how to do this if not google it), i only disabled the shadows and animations because the rest just looks cool.
4. REGISTRY TWEAKS/MODS (google search it and you should come up with tons, they almost all improve performance or ui).
5. delete unused programs (we all have them, you can't deny it).
6.go to %temp% every once and a while and clean out what is left behind by the temporary file cleaners, if any file cannot be deleted then just click skip.
7. if you run firefox then this tip will really speed up your browsing... just as an extra tip. google for about:config mods/tweaks.
8. I reccomend this program by bitstrum called Process Lasso, it monitors every process, how much cpu usage, ram load, and virtual memory your computer is using and allows you to set permanent priority levels and throttles for every one. it also has a process watchdog allowing you to say if _______ is using ______% of ________ then ________. it comes witbh a tool called probalance witch sort of can try to work to balancing your cpu usage and responsiveness too!
9. This tip really helped me make my laptop so much more responsive, but it changes windows default memory usage. go to command prompt and type FSUTIL BEHAVIOR SET MEMORYUSAGE 2 (this will require a restart)
as some extra tips i will say right click your hard drive and go to properties, go to tools and start a disk check. it will prompt you to postpone it to the next startup and on the next startup it will open all MSDOS style and take a bit of time to do a full checkup. I find that this is not often usefull but you can try it if you want. another is to make sure your computer is NOT indexed... indexing may increase speed of searching but it deteriorates speed of the overall pc.
I hope this was helpful and i would like to note that this is my first time using answers.com...
