The possible harm it could do to your pc

Once a virus such as Trojan/Syswin gains entry into your computer, the symptoms of infection can vary depending on the type of virus. Some viruses can keep adding shortcuts of other programs on your desktop, while others can start running unwanted programs, also referred as “PUP” (Potentially Unwanted Programs) to intentionally slow down your computer.

There are also more harmful viruses that present the infamous “blue screen of death”, a critical system error that forces you to keep restarting your computer. Viruses like Trojan/Syswin can even delete your important files and folders.
