- Don't download suspicious files
Cons: Sometimes you just need to download these files
Like what suspicious files are these? Cracks? Torrents? ROMs? If you need to download these files then you won't think of it as suspicious.
The better term would be, download files on their official website or make it a habit to read reviews. Sometimes these files can also be found in a forum so reviews are available.
The bottom line, the virus will not enter the system if no one allows it. Always think before we click.
As for me I love to download files with crack license, sometimes I also think of the risk that my laptop might be compromise but when I tried one time and nothing happens to my files, I then continue to download more files/programs from different forums, what's important here is to always read the review and download only those files with good reviews.
If we like to feel safe because we have our wallets information stored in the PC or Laptop we are using, maybe buying another device would help, secure the necessary information to the other device and don't install or download anything using such device.
