I brought over my younger brother’s pen drive today to install some games and scanned the pen drive with my avast premium. Note : I never opened the game folders but some games were exe files. Avast found 3 viruses, trojan and malware. I selected “do nothing”, copied the games that avast didn’t highlight as infected and quickly went back to my brother’s house and told him his pen drive was infected. So, i did another scan on his computer with his avast free version and surprisingly, no viruses were found. I left him to do a full system scan anyway. Here’s what i wanna know :
why his avast didn’t detect anything while mine showed 3 infections. is it because he is using the free version and I, the premium?
Can you get infected simply by plugging in the usb or only when you expand the folders that are infected?
Can I use the games that weren’t shown to be infected and delete the infected ones. Would the pen drive be safe/clean to use?
First thing to do is install a dedicated USB malware detector/cleaner
Download MCShield to your desktop and install
It will initially run a scan and show the result as a toaster by the system clock
Then in the control centre select scanner and tick unhide items on flash drives
