AVG reporting a trojan horse and a virus


potwnc

Recommended Posts

I'm using a friend's PC so I came in through the main url - www.picturestoexe.com. AVG reported a trojan horse. I clicked on the link for the forum and AVG reported a virus. I think AVG (free edition) is quite reliable although I don't use it on my PC. Can anyone confirm whether any other anti-virus software reports anything suspicious coming in the way I did?

GRISOFT AVG - Free Edition

BE AWARE ~ When the 'Trial Period' of this program has expired it appears as if it is 'Updating & Installing'

new Virus Definitions etc. I have mentioned this before on this Forum.

Yes, it is downloading these but it DOES NOT update your (expired) Free-Edition.

Please read their 'Documentation' and this will be confirmed.

Recently two of my Customers have lost:- A brand new XP-Pro (6 months old) and another a 2000 Pro.

Both PCs' fell victim to a 'Coolwebsearch Trojan Bundle' and both PCs' were using an expired Copy of AVG.

The Program also suffers from 'False Positives' alert activations.

To be REALLY SURE that your PC is virus free ~ Download a 'Free-Scan' of the XoftSpy Utility from

www.paretologic.com

for the details see

http://www.picturestoexe.com/forums/index.php?showtopic=3681

it was related to a certain version of p2e -- and the exes were cleaned but the pte was left alone

avg straighted things up in a couple days

i will add to this -- after that episode i set up test folders on my drives, so i can test specific things -- by doing a global scan i lost +- 3 gb's of pte exe's - they grey matter was not working too well that day

a good starting point to test your anti virus is to get "eicar" test file

http://en.wikipedia.org/wiki/Eicar

you will do a right mouse and a save as to get the zip file -- you wont be able to mail it to yourself if your isp's anti virus protection is working

or you can make one

I am using AVG 7.5.432/Virus Database: 268. 15.29 608 UPDATED Dec. 29 2006.

last week showed no problems. but after downloading the udate today, AVG found 21 PTE shows with the Trojan Horse virus. i beleive it is a false reading, but will leave them in the virus vault until something is resolved. Has anyone else checked lately. Has Grisoft been notified and is something being done by them?

Opening my folder on shows from Beechbrook today, AVG (7.5) flashed up that the file Kula.exe contained a Trojan Generic2.nxu.

Considering Kula was downloaded some time ago without any alert before now I was inclined to think false positive. Nevertheless, Kula was placed in the virus vault and I went searching for an answer. Entering the trojan details into AVG's Search Virus Encyclopedia result was, 'no record of this virus.'

If AVG has no record then how can it cause the alert? Kula remains in the vault until this is fully resolved.

Hi Howard,

AVG has had issues with a number of false positives for quite a while now. Their operating philosophy seems to be that if they don't recognize something it's automatically suspect. Unfortunately that shotgun approach leads to any number of false positives including what you are seeing.

I gave up on AVG a couple years ago and purchased a number of top-rated anti-threat, anti-spyware and anti-trojan/anti-worm programs including Nod32, AdAware, Trend Micro, Spyware Doctor and ParetoLogic.

I run each of my executables as well as my entire system and peripherals with all the above. No singe program yet finds "every" possible variant, but this combination doesn't miss much. I've never experienced a single problem in 5 years with PicturesToExe executable files and I don't think there have been any in the past or any at the present time. Chalk it up to AVG's being overly cautious to the point of interfering with perfectly normal functioning executable files.

Best regards,

Lin

Thanks Lin, I have had no problems with the free version of AVG, except for these false positives, for about 4 years now. I do like the efficiency of the AVG free program in stopping problems. I seem to remember that the last time we had this problem with the false positives, Igor contacted them and they correctied the problem. Igor, are we giving up on AVG now? If so I will take Lin's advice and go to another program.

I'm sorry for this problem!

Kula slide show NOT infected.

This slide show created in old version of PicturesToExe v3.60 and this false detection of AVG already happened two years ago

Now it seems that authors of AVG antivirus forgot about this and again marks slide shows created in PTE v3.60 as virus.

I'll write them again.

If you can please write also to GriSoft it will help to solve this problem more quickly:

Example of slide show created in v3.60:

http://www.kulamaui.com/slideshow/kula.exe (20 MB)

p.s. it seems that we are not able to send a letter to GriSoft because technical support and any contact information only for registered users. We'll try to send the letter to sales department.

I have AVG Free on my main graphics computer and AVG PRO on 6 other computers. PTE runs fine and I have never had a single virus threat or mention of one from AVG. Isn't that weird how variable these programs can be from one machine to another?

did you download --

Kula slide show

"This slide show created in old version of PicturesToExe v3.60 and this false detection of AVG already happened two years ago "

it tested a threat with my avg but clean with 2 other scanners

it generally takes avg a couple days to correct the error

way way back there were also 2 shows -- one was called peru -- i forget the other one

and Hawk Bill Hines and my self scanned everything that was on the Cottage - 250 meg i downloaded - that time it was Kapersky or Norton that was at fault

Guess I didn't Ken. Don't have it in my show archives. It's nice however, that I have not experienced the problem. AVG on the other hand, has caught many gremlins trying to invade my space over the years and I've really been happy with it. It is so seamless and doesn't bother me with popups. Well, at least until recently anyway... They've begun anouncing the end of the current free version and want us to upgrade to the pay version.

larry

oh, and Happy New Year to you.

Kula is still available on page 9 at the cottage -- as well so is

Trip to Peru

Download Count: 2038

they were made with old version and cause a notice to be displayed by my avg -- you should download them for test purposes of your antivirus system.

Avg announced last Nov, ver 7 would be discontinued in eary 2007 and people should urgrade to the free ver 7.5 -- the way they worded it has caused much confusion as to continuing availabilty of the free version

You weren't the only one. I made the same mistake when I first

received the alert from AVG a few days ago.

AVG in its present state will not even allow the KULA OR THE TRIP TO PERU - to be downloaded - and i just updated my avg to see if the problem was resolved - so the Kula file i had for testing has gone bye bye -- not even in the vault :angry:

Yes, I tried it. The download was interrupted by AVG announcing the threat. My version of AVG is the PRO version 7.5.433 and it's up to date.

Avg announced last Nov, ver 7 would be discontinued in eary 2007 and people should urgrade to the free ver 7.5 -- the way they worded it has caused much confusion as to continuing availabilty of the free version

I'm getting that pop up on my free version with the announcement daily. It's interesting that by following the links of the popup, there really isn't any way to get to the free version download. It is available and they say it will continue, however it is becoming increasingly difficult to find the download for the free version. I have many friends and from time to time give them a heads up on this great AVG program. The last 4 people I sent to grisoft couldn't find it.
