The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

How to delete the  "Downloader.Trojan" virus ?

Asked by cross-ways in Miscellaneous

Tags: virus, remove, how, installation


My Norton Antivirus 2005 (Internet Security 2005) has detected the following virus (which it cannot repair or delete) :

Loadadv458.exe
Downloader.Trojan

The location of the infected file is:
 
C:\ProgramFIles\Common Files \ Wise Installation Wizard\WISCDEBF9E7BCEB43A7986CE66377C28ABC_1_0_0.MSI


This is what I have tried so far ( which has NOT resolved the problem) :

1) Tried to delete it from the quarantine list - from the "Backup items" - but it still shows up again.

2) Scanned with “TrojanHunter”, which detected and removed the virus. However....when I did a new scan with Norton, it reported that the virus was still there (that I am still infected). I then ran the TrojanHunter scan again...which then indicated that I had NO infections or threats…but according to Norton, I still have.

3) I scanned with "Trend Micro House Scan" , which removed a lot of things (but nothing looking like the Downloader.Trojan virus. (while doing this scan, a  Norton "announcement" suddenly showed up explaining that Norton had detected and deleted a virus named "Downloader.Trojan" ...and DELETED it ! , but it still showed up in the next Norton scan I did.

4) I scanned with “Spybot – Search & Destroy 1.4”, which didn’t help.

5) I followed the suggestion in the Symantec link: http://securityresponse.symantec.com/avcenter/venc/data/downloader.trojan.html.... and did a Norton scan in Safe Mode + looked for anything suspicious in HKEY_local_machine/software/microsoft/windows/currentversion/run
HKEY_local_machine/software/microsoft/windows/currentversion/runonce
HKEY_current_user/software/microsoft/windows/currentversion/run HKEY_current_user/software/microsoft/windows/currentversion/runonce
…..but nothing changed.

6) I tried out the Hijack Spyware Tools ( HijackThis 1.99.1)...but I am afraid that tool is too complicated for me.

7) I scanned with “ScanSpyware v.38”…which detected many things, but they require that you purchase it if you want to use its cleaning tool (...and I have no credit card).

8) I scanned with the “Ewido Security Suite” software, which detected and deleted a number of spyware threats, but did NOT detect the virus I have – not in the full scan, and not when I went to the windows file that is infected, highlighted it, right clicked it and choose “Scan with ewido” (doing the same with Norton, the virus is detected

What else can I do…that is not difficult for an amateur like me ?

Grateful for any suggestions?

Hans

Ps. I am running on a Windows XP Home
