  2. I’ve been getting the Win32:Evo-gen [Susp] repeatedly for the past few days, but when I do step 1 on here, nothing comes up?

  3. Hello,
    If you have downloaded your drive from its manufacturer than you are safe.
    You can submit the detected file to be scanned with multiple antivirus engines at:

  4. Hi stelion, I reformatted my windows 7 a few days ago and installed como do firewall, avast, and malwarebytes (is this enough??) And I was about to install my printer drivers but avast suddenly said A THREAT HAS BEEN BLOCKED!win32-evogen and I wondered weather it was just a quincidence or there’s something wrong with my drivers? ? Anyway should I still do all the steps or something else?? Thanks a lot for the steps and the response :) ps is my current security set up enough.

  5. In my case, it’s the following file, can’t find anything about it.
    It’s in Avast quarantine

  6. Hello,
    If Avast has moved the file to its chest then you should be safe! Even so, just to be on the safe side, I would suggest that you run a scan with Malwarebytes and HitmanPro.
    Stay safe!

  7. At first Avast constantly blocked the virus then ı guess it got in because avast put it in the virus chest along with a win32 adware gen Adw am ı safe or is my computer infected with a very dangereous trojan? And if ı wish to terminate the viruses in the virus chest what do ı do?

  8. I am a software developer and everytime I code something with Caller Information (that is a new feature of Visual STudio 2013), avast detects this threat. But it is a false. The problem is that every new development is new file and is detected again

  9. Hello Lucky,
    It depends. Win32 Evo-gen is a heuristic detection, so an antivirus may pop-up this alert for another type of infection. Just to be on the safe side, I recommend that you follow the steps from this guide:) ….

  10. Hello,
    PGPfsshl.dll is a related to PGP Desktop, and it’s not a malicious file, so basically this is a false positive.
    Here are more details about this PGPfsshl.dll:
    PGP Desktop is a security tool that uses cryptography to protect your data against unauthorized access. Hard drive encryption software locks down the entire contents of a laptop, desktop, external drive, or USB flash drive, including boot sectors, system, and swap files. Creates storage-independent encrypted containers for transport and sharing of specific files using included utilities; PGP Self-Decrypting Archive, PGP Virtual Disk, and PGP Zip.

    So now, you have two options:
    Either you add this file to Avast Antivirus exclusions, or if you don’t need PGP Desktop, you can uninstall it from your computer.
    Stay safe!

  11. Hi! Thanks for the great article. I’m getting really annoyed. Avast detects Win32:Evo-gen, I’ve run tdsskiller, mbam, Mese and hitpmanpro and neither finds it. I’m almost starting to believe it’s an Avast hoax to do an upgrade….
