Oh no, what am i suppose to do? i am suspecting one of the downloaded executable file(*.exe) as a virus.
You may ask me, "how you are suspecting it as a virus program?"-very simple.
By checking the Icon of that executable file:
1.you may have seen that icon before in a good program.
2.uncommon/usual icon
By searching the company name in any search engines like google,bing,yahoo to confirm the accuracy of the information available in the properties of that executable file.
By checking the properties of that executable file, where you can find the information about the company or the person who has created that program.
By checking the name of that executable file.
virus integrated files may comes with very famous names like facebook.exe. So, if you feel, the name of that executable file is irrelevant for that program. For an example: you are downloading a program to convert the mp4 videos to avi or any new video formats but if the name of that program is like 'chatnow.exe' then you must suspect it.
By checking the file size of that executable file. [Optional] but, please don't compare the size of the file because some time you may download a program which has integrated virus then this file size checking way is not good to use to identify the virus.
By checking the used language of that executable file.[Optional]
For an example: you are downloading an English version of audio converting software but the descriptions and the title of that executable file are in different language. Then you must suspect it but not always because there are some software created by a group of people whose mother languages are not same. So it also optional.
By checking the above mentioned things, you can suspect a downloaded file as virus.
You may suggest me to scan the file with your installed antivirus program. But how do you ensure that your antivirus has the necessary details to detect it as a virus because that virus can be new to the world, and if you are not updated your antivirus virus database for long time then you can depend on its scan result.
You may ask me, then how?

Are you suspecting only the executable files (*.exe)? Please don't because viruses may come in different forms, and in different format. So you have the knowledge to suspect any files (even *.txt format files) if they are downloaded from unsafe websites, torrents..etc.
If you have ever met an incident like suspecting a file as virus then you have to check that file with your installed antivirus program first. If it says not harm, please don't believe. Connect your computer with internet.
