If you’re a vintage computer collector or someone enjoy using old computer like me. Once in a while you might, in inadvertently downloaded softwares from a questionable source which may contain virus/worm.
Overtime, I have taken many precautions to avoid such problem. But, the idea of having to buy Virus scanner software and pay yearly subscription fee to me is ridiculous.
A better solution I found is to use a free on-line virus scanning services which will use multiple virus scanners to look for potential virus or worm.
Once such service, I found is https://www.virustotal.com, you simply upload the file in question and after while you will get the scan status report. After which you can rest assure the file virus free.
