How do you know if you have a Keylogger virus?

If it's well designed it should be hard to spot. Best way is to take the approach below to scanning for any kind of malware and removing it in the correct way.... In order to successfully remove malware infections (viruses, spyware, adware etc) from your PC you need to follow a methodical approach as well as using effective (and free) tools. There’s a decent guide covering this that you can work through at My Slow PC (http://www.MySlowPC.co.uk/) – click on the “Troubleshooting” link. Here’s my advice from it: 1.) Turn System Restore OFF so any infection that you remove is not restored. 2.) Scan with a combination of the best detection utilities as you’ll find different scanners can sometimes pick up different infections. E.g. * McAfee Stinger – a free stand-alone utility used to detect and remove specific viruses. * SpyBot Search & Destroy – a spyware/adware scanner * Lavasoft Adaware – for spyware/adware Note – it might be a good idea to disconnect your network connection once you’ve updated them with the latest virus/spyware definitions. This is due to the fact that often an infection is trying to spread over your network. 3.) If the above fails or you’re not sure if you’re still infected, when you start your PC tap the F8 key, select “Safe Mode” and repeat the scans once you’re connected. I hope the above helps, as mentioned the guide above is a lot more detailed and the My Slow PC site is pretty useful. Good luck!

KL-Detector is designed to provide a way to find out whether your activity is being recorded with a keylogger application. It uses the fact that most keyloggers create a hidden log file on your hard drive and therefore scans for any suspicious activity during a test period that you have to initiate. Basically, it asks you to use the keyboard for several minutes, type some text or do similar activities, while it is monitoring your system to check if it can detect any suspicious logging activity. KL-Detector is intended for occasional use and not as a permanently running program, as normal PC activity may cause false positives. During our test, it did detect changes in a keylogger log file (that we installed), but it did not find the activity suspicious enough to warn us. Advanced users may get value by inspecting the logged items, however novice users should not rely on the results. Freeware. http://www.snapfiles.com/Freeware/security/fwantispy.html

they are no symptoms, you should scan your pc will a spyware(spybot) or maleware (malerarebits) to check if you have it, or update your antivirus, one way to find out is when yous pass are changed or when you install a software and it does not do anything, or when you check your task manager and see strange things running.

Run a good antispyware program should find a keylogger. @Rommel - posting the same answer over & over again, is called spamming, do you wish to be band again.

better to be safe do this to make sure u dont get one and there is no way to tell if u only get a keylogger Step 1. Download Avast! Home Edition as this is THE best free antivirus protection out there. Only drawback is you have to register within 60 days for free and every year after. But hey! You get it forever! Anyways you also have to manual scan, but it isn't a resourse hog and it scans everything your computer writes and reads as well as internet sites and emails. I love it. As well they update it about every day! It found several viruses after I deleted Norton 360 and has found several since. Download here: http://www.download.com/Avast-Home-Editi... Register here: http://www.avast.com/eng/home-registrati... Step 2. As well try downloading malwarebytes anti-malware, updating, and scanning. MBAM redirects you here for download. (MBAM) Go here to download: http://www.download.com/Malwarebytes-Ant... Step 3. Proceed by downloading "SuperAntiSpyware Free" from the link below (As the title suggests, this is also free), follow any instructions required to install it, update the virus definitions, then run a full scan, also clean any infections found after the scan has completed. http://www.superantispyware.com/ Step 4. You may also consider to be sure that all Malware has been removed from your system download “Kaspersky's Virus Removal Tool" (Free) from the link below and run a full scan, this will already be updated to the day you download and install it, after the scan clean any infections found. download here http://devbuilds.kaspersky-labs.com/devb... Step 5. Consider doing a scan of your computer with MBAM and superantispyware every 2-4 weeks with a maximum of a system scan every month. (I recommend 2-3 weeks.) P.S. make sure to unistall all other antivirus products before installing avast and never have more than one installed at a time. Hope this helps and enjoy a better computer!
