Remove infected \Windows\System32\str.sys (Rootkit.Agent)

Recommended Posts

Hi,

MalwareBytes detects \Windows\System32\str.sys and c:\Windows\SysWOW64\drivers\str.sys infected. After removing them, restart our PC and scan again. MalwareBytes still detects these two files infected. This is the very similar of topic# 28898. I have attached a MalwareBytes log file. Do I have to run ComboFix?

Additional information is

1. OS is Windows 7 Home Premium.

2. Registry Keys and values might not be correctly set up because they are removed after infections.

3. Microsoft Software updates crashed our PC again. So that I currently stop running Auto Updates. The number of pending updates is over 100.

Thank you for your help

Hello and welcome to Malwarebytes yucunn :)
