Hi, with this type of virus, it will be difficult to remove with installed antivirus program. Try a bootable scanner from Kaspersky.

This can be booted and run from a CD,DVD or USB Drives.

My Norton anti-virus sends me pop-ups every minute or so saying that it is blocking security risk Heuristic.ADH and that my computer is secure. I can not get the pop-up boxes to stop popping up every minute and it is driving me crazy. I did a chat with Norton and they basically said that they could only turn it off for 24 hours and it would come back which it has. How do I stop this without ditching Norton and going to some other brand of anti-virus? If I have to switch, what brand is recommended? Much thanks.

Every time the pop-up comes up, whatever process I’m running, an online game for example, stops, even minimizes, until the pop-up goes away about 8 seconds later. It prevents me from playing the game. Just one problem of several with this thing. I thought if the threat is blocked it does not infiltrate any files. But how or why does this trojan continuously attack?

I had the same issue with the Norton pop-up. I found a program on my computer called Relevant Knowledge and uninstalled it this morning. Since I rebooted it has not happened again.

Ok I just researched this a bit, and apparently its a tracking cookie of some sort. I am also a Norton user and these annoying messages were affecting me as well. To REMOVE this annoyance, go to control panel and look for a douchebag program called Relevantknowledge and uninstall it. Then restart your computer. Next, go to c:\users\owner\appdata\local\temp\*now delete anything that is along the lines of ~os2DF5.tmp at the reletive time of Norton’s message* AND finally it should be gone! :D
To prevent tracking cookies completely, (on Internet Explorer) go to Tools, Internet options, privacy, and set the bar to “block all cookies.”

People, people, people…. trojan.adh, heuristic.adh & spyware.adh are Symantec’s weak attempt at zero-day exploit detection. They will quarantine or delete any file they don’t like the looks of, which has caused many individuals much headaches. Use common sense when browsing, downloading and installing software, and be careful about arbitrarily deleting files from your computer just because Symantec said you have to. Not knowing exactly what you are doing, you may end up screwing your computer up far worse than your average run-of-the-mill spyware or trojan would have.

I have seen people complaining about it but? honestly speaking it’s not a virus. The software is used to measure online activity. I also thought it to be a virus initially but then found their website relevant knowledge dot come. I did not have any problem in uninstalling it.

Thanks for posting this video. It provides useful information. I would like to add my 2 cents though. Some times it is not as difficult to delete unwanted programs as people think, Usually spyware stops users from uninstalling genuine programs also. relevant knowledge is one such example. It is not a virus. It’s a genuine software installed with user’s permission.

Relevantknowledge is not a virus. It is a Research software. If you find it annoying, you can uninstall it from control panel. You can read more about this software on their website relevantknowledge.com
