RelevantKnowledge (rk.exe)

Oct 20, 2004 5:15AM PDT

My Computer:
Win 2000 Pro SP4 - Pentium III/1GHZ - 256MB - 30GB HD
ZoneAlarm w/Antivirus - Spybot S&D - a2(malware detector)
IE6 - Comcast Broadband connection
For 2 days, RelevantKnowledge has asked for internet access & server rights thru ZoneAlarm.
1st request IP destination is which is CERFnet, AT&T Broadband.
2nd request IP destination is which is Sequent Computer Systems (IBM) in Vermont. (Sent them an email.)
3rd request IP Port 8254 for Server rights.
ZoneAlarm has no info on this. I OK'd the first two & denied the server rights.
I've had no problems crop up. I've researched Microsoft & done internet searches with no results. The only thing that has changed on my computer is I downloaded some Clip-Art from
**I would like to know what RelevantKnowledge (rk.exe) is, what it does, why it loads on start-up and do I need it???
Thank You for any info you can provide.

I also received a msg from my firewall that I was under Port Scan Attack from Sequent Computer Systems in Vermont (IP 12:58 PM today. Sounds like they have a hacker on staff.

Also, rk.exe is spyware. Delete it, or get a good spyware program (I use Spybot and AD-Aware one after the other - both are free) and sweep your system.

Spybot and Ad-Aware didn't flag it for me. By searching through the registry for rk.exe it looks like it's associated with a toolbar of some sort. Also found in a reg key an uninstall string (c:\winnt\system32\rk.exe -bootremove -uninst:RelevantKnowledge) I ran this then renamed the file to see if it comes back or is needed by something else.

The other people replying to your problem went at it the hard way. I went into add/remove programs, removed it, did a restart and VIOLA all gone.

rk.exe "Relevant Knowledge"
Jan 24, 2005 4:49AM PST

I can pinpoint when I got rk.exe because ZoneAlarm alerts me to new programs that try to access the internet. It began immediately after I downloaded one of those free screensavers that are advertised all over the internet. To get the screensaver, you end up having to install a Yahoo toolbar and a lot of other stuff.

The rk.exe program was simple to unistall from Windows XP. I just went to the control panel / add-remove programs, and selected "RelevantKnowledge" and - zap! It was removed.

I didn't know how to get rid of this until I read your message. I use Windows ME and did the same thing you did, went into my computer, control panel and add/remove programs. I removed relevant knowledge, and then ran a search from the start menu and found the rk.exe file and deleted that. No more rk error messages. Thank you for helping me with that problem.

rk.exe issues
Jan 30, 2005 10:17AM PST

I found that I had this spyware program. When I disabled it with Spybot my internet connection slowed to a crawl. When I re-enabled it my connection speeded up again. I do not want it on my computer so I followed the directions here and deleted the file and searched my registry and removed any trace of it there. My problem is that my internet connection has slowed again, to a very slow rate. Anyone have any solutions?

rk.exe deletion

I have removed the knowledge via control panel then re-run search, it is still finding this entry can anyone tell me if it is safe just to delete it: this is located in a Windows file called Prefetch.

rk.exe deletion & Prefetch
Feb 12, 2005 7:44AM PST

My computer has just had been invaded by the rk.exe file, where it came from, who knows! I managed to remove it from my system by using the add or remove program in the control panel .... it worked a treat! Regarding the trace file detected in PREFETCH, you can delete this, and all of the files in this folder, as it is basically a recording keeping file of all the activities your computer has been requested to perform. Hope this answers your question.

I just found this in the Windows/System folder. I right-clicked on it, chose "Properties" and on the "Version" tab for "Product Name" it says "RelevantKnowledge Internet Accelerator". It is not in my Add/Remove Programs.

cannot delete rk.exe using control panel
Feb 24, 2005 4:42PM PST

I tried and it said that it is already deleted, and asked me whether I wanted to delete the icon from the list afterwards... how can I delete this thing!

It put itself alot of places in the registry, amongst them in --> HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\

As enabled, what it means is that it gives itself the rights needed to bypass the windows standard sp2 firewall.
Shows again how windows builtin security is but a joke.
