Greetings,

During the usage of Firefox browser, suddenly i found downloaded file in the profile folder, but this is always happen each time i delete the file it comes back again, Fortunately i have a Norton Internet Security with the Download File Insight feature i could discover that file and followed the cache folder of Firefox Browser and it is not a virus, Now these issue was happened after i have installed a program named virtual router on Windows VISTA,

After rename the file in cache folder to .exe extension it shows the setup file mentioned the wireless icon, by running it it shows the normal setup of Winhostspot,

What shall i do to stop this downloading file without permission? Do i have to uninstall the virtual router software?

I'm sure that i have no virus cause the Norton Internet Security is up to-date with all running its security features: Virus definition and Firewall ... etc.

Even i have scanned the file by uploading it to http://metascan-online.com/ Thanking your cooperation, we remain.

Best Regards

Hello ,

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

More information about reinstalling Firefox can be found here.

WARNING:Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.

Please report back to say if this helped you!

Thank you.

A uninstall and reinstall as suggested by iamjayakumars is a waste of time in this case.

The viruses/Trojans and other such files found in Cache is harmless unless you manually try and run them and they will get overwritten over time anyways unless you manually cleared Cache.

Sometimes a recent definition update can cause false positives and another update is needed.
