Yesterday avast showed a virus warning message on file called "svchost.com" inside C:/windows/. I have removed it and reboot the system. After a reboot, some of the exe files in Downloaded folder and Program Files and some installation files in other location changed into blank icons(default icons changed).
I scanned those exe files with Avast but no virus warning msg. So i have tried to open it but i am getting this error message "the files or directory is corrupted and unreadable". Only some of the exe files are changed into unusable but some exe files are in downloaded folder are still able to open.
I thought reinstalling OS will fix the issue.So I have reinstalled the OS. But still exe files are unable to open. Newly downloaded installation files are working fine. Only old installation files are not working. I have installed Bitdefender and scanned those files no virus warning.
Am i infected? Any idea on issue?
