Sometime ago I was using my computer without installing antivirus. My friend told me its not good to use compute without antivirus so I asked him to suggest me some better antivirus and he suggested me this Net Protector Anti Virus. I was very excited after installing the NPAV but I was unexperienced with antiviruses.I had saved many non-supported media files on my computer when I run the full scan it deleted all that files.
I was very shocked at that time that without my permission how it could be possible, NPAV showed me that these files were harmful for your computer so NPAV deleted it from your computer without any external permission.NPAV does not understand the extensions which are not supported by the media players and some readable files too.
You can easily check by renaming any living file to other extensions like file.tkk or file.ht it would delete it as malicious programs are deleted by default .I dont like this antivirus because it deleted my many secert files and data.And I would never recommend anybody to buy the antivirus.
When called to their cutomer care support they told me NPAV only deletes malicious programs which are harmful for your computer so it deleted that kind of files.Even they were not ready to keep my words.So bad support for the customer.Dont ever think to have this antivirus.
