Video/audio conversion application

Hi nsofos
 
Welcome to the Community Forums.
 
Well, take your pick...as there are many out there...you just need to do a little research and then, which is most important, download the selected application from the author's website or from another site that they have recommended.
 
This is because what I suspect that you are seeing and referring to as 'viruses' are in fact non-malware programs; what we call, in The Community, PUAs or Potentially Unwanted Applications.
 
These are very annoying at best in that they cause pop-us, redirect your browser home page, and other behaviour that may slow down the computer and direct ads your way, but they are not actually doing anything bad like damaging files or stealing information. Often they are installed intentionally by you the user as browser add-ons for various tasks such as quick search tools. But they also come with the result of added annoying pop-ups and ads. Other times they 'piggy back' with other software that you installed, or try to 'sneak' onto your system entirely.
 
So, as previously stated above, the key to avoiding them is to make sure that when downloading apps one does so from the author's own website or one that they have recommended, and not 3rd party downloading site.
 
WSA does detect and remove many PUA's, and more are being added, but WSA does not detect all of them. A simple browser add-on with PUA behaviour that is easy to identify and easy to remove is not likely to be detected and removed by WSA. Those that are intentionally difficult to locate and remove are. Please see this link for more information regarding Webroot's stance on these annoying programs.
 
Finally, to help you with your search take a look here; this from a very reputable site that I use a lot and whose advice can be trusted.  And remember...download from author's websites where possible...;)
 
Hope that helps?
