Hello
Today I have been experiencing very weird situation. I did scan my pc with avast5 internet security before boot , and it found that file named aswRunDll.exe is infected with win32:malware-gen.
The path to the file was starting with "windows.old" folder full path was windows.old\program files\alwil software\avast5\aswRunDll.exe , i put it in chestbox and when i checked the path if the file is still somewhere there, it was missing , so I assumed its ok and problem is fixed. But when I did some digging I found out that I possibly have 2 windows folders , 1 is the main and other is backup which I probably created back then, probably the "old" one is where It found that malware so the backup folder.But when I open the normal folder from program files the file is there , but isnt infected or anything , atleast thats what avast says when I scan it. It was only in the back up folder which isnt right now because its in the chest.I do scan PC regulary so Im wondering why it didnt find the malware before if it was rly malware and if it was there long time. Or If I cought it somewhere lately or before why the shields didnt blocked it or atleast warn me? There's also option to " report it to virus lab " when I right click on it in the chestbox Should I try that option or is it all ok now? Could you please help me with this issue? Btw sorry for the bad english , hopefully you understand.
Thanks a lot to everyone. Regards
