Viruses that Avast is not detecting

Viruses and worms
1

I have purchased Avast Professional and Server that are kept up-to-date and have still been infected with viruses.

I had to use Ad-Adware SE Personal with 2009-03-23 definitions (from a boot cd), and Windows Defender 2009-03-22 definitions to remove the following viruses that Avast skipped (even with several boot time scans):

  • Win32.Hacktook.Keyfinder
  • Win32.Adware.Onflow
  • Win32.Trojan.Packed
  • Win32.Trojan.Agent
  • Win32.Trojan.Zheletin
  • Win32.Trojan.Downloader.Zlob
  • Win32.Trojan.Oliga
  • Win32.Trojan.Vundo.gen!AJ
  • Win32.Trojan.Vundo.gen!G
  • CPMcfab59ox - sosazeri.dll
  • CC986a93 - bufezeza.dll
  • LSA Shellu - nilimuvo.dll
  • horijavu.dll
  • pisuvedi.dll
  • elwqml.dll
  • pogepehe.dll
  • wanebape.dll
  • tapeyeni.dll
  • CPMcfab590
  • nuyasipana

I had to manually delete some of these dlls but they keep coming back. I am using StartupMonitor now to tell me when these items are registered but its popuping up all the time.

I got these viruses from a USB flash drive that was used in another computer that also had Avast installed and was up-to-date.

Avast should be doing its job and protecting my systems from viruses!

When will this be fixed?

Today I discovered that one of my computers was infected with Trojan.DNSChanger and Trojan.Agent. This computer is running Avast! Free Edition and is always kept up to date.

How did this happen? Why didn’t Avast! stop these infections?

I have spent hours today trying to insure that I do not become a victim of identity theft because of these infections. I have been considering purchasing Avast! Professional but this disaster is making me think twice!

Just send the infected files to alwil so they can add it to their Virus database so it won’t happen again.

Seriously, did you have to bump a topic. -_-

I don’t understand. Why is it bad to reactivate a topic? Isn’t it useful to have background information to go along with my post?

If I’m not supposed to do this, I won’t. But I’d like to understand why.

Thanks!

Because its a old topic. You could make your own topic and get more people to anser your questions.

It’s not the problem (if the problems are related), but posting three time the same, well, won’t help either.

I deeply apologize! My mistake.

I will restrict all future discussion of this issue to this thread:
