Trojan Horse Downloader Agent AQN

by seafox13 / November 10, 2005 12:01 PM PST

A friend running Win98se has contacted me to tell me she has a warning message from the AVG antivirus MBR scanner that refers to Trojan Horse Downloader Agent AQN, and advises to run the AVG Rescue Disk, which she has not made.
I assume that she has no option but to continue booting up, then scan with AVG and run Spybot S&D, then Adaware Personal.
Does anyone have any relevant suggestions, please?

Thanks for the tip, Donna.

However, she tells me that she managed to boot up in safe mode, and has since "returned to an earlier time" using DOS.
The error report has not showed up again, thankfully.

CNET has trojan horse downloader in adaware se personal!

I downloaded Ad-Aware se personal from the CNET site and AVG told me it had Trojan horse Downloader.Agent.AQN in it. AVG has healed the file but I feel CNET should remove the infected program from their site.

Toxic, It Could Be A False Positive..
by Grif Thomas Forum moderator / November 14, 2005 8:48 AM PST

It's good to be cautious before automatically deleting something. There's been a discussion about that particular trojan on the AVG forums. Apparently, AVG virus defs have been discovering a few false positives in a lot of "good" programs. Apparently the definitions from November 8 and 9 were showing some incorrect detections. Have you updated to the most recent definitions, then run the scan again? Before the scan, have you turned of the "Heuristics" option so that only "known bad" detections are found?

See the link below:


Hope this helps and let us know more.

I just sent an alert on this

just so it can be checked out by the appropriate people Grif but I would think is would be a false positive also.

Received the emails from you and Toni...

I'm willing to bet it is a false positive also, but I will forward this concern to the folks at download.com to look into. I don't know what their response time will be, but they usually are quick to look into these matters.

Personally I think AdAware would be killing their business and trust of all the people who use their product, if they decided to turn to the dark side with Trojans. That would be such a disgrace and disservice to all. Let's hope it is just a false positive as Grif posted.

If anyone of you have experienced the same as this member did above, please chime in to this thread.

Thanks everyone!

FYI: It is a false positive
by Lee Koo (ADMIN) CNET staff/forum admin / November 15, 2005 3:32 AM PST

Just spoke to the download.com team, and they are aware of the false positive. Their editorial team has contacted both AVG and AdAware and made them both aware of the problem.

I hope this note and Grif's posting in reference to this false positive helps elevate some of your concerns.

Best regards,

Hey, well i got this virus and was infected 6-7 times. but there is a solution!!! Go to start, Control panel, (on the left) Help and support, (under pick a task) undo changes to your computer with system restor, and then follow the prosses. make sure to pick a date that was befor your infection, and copy any VERY important files, b/c any newly added or saved files will be deleated back to the chosen date/point. but yeah it did fix my problum. so kool deal. glad to help and hope the makers of viruses/spyware/trojans and crap all get whats comming to them b/c viruses suck! Lol but hope your problum gets resolved and hope this might can help any others that might encounter a problum!!!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
