Hello everyone, I am new here. I am a user of NOD32 anti virus and AVG anti spyware. Recently my PC has been affected by a malware named Trojan.PolyCrypt.b. My NOD32 has been updated however it cannot scan out this malware while my AVG can only scan this out as file under the system volume information of my c drive. Here is the problem, since there is only one file that can be found is detected, I first tried to delete and of cuz it does not work and after reboot it comes out again. So I quarintined it and tried to use my PC normally again. However, few days later it became another file in system volume information and my PC runs wierd again. I tried to find out solutions from internet but seems no help at all. therefore I came here and I hoped anyone can help me to delete this malware. Thank you!
