    Default Can a virus re-download itself after anti-virus deletes it?

    Hey interesting thing has been happening to my laptop. My Avast has been going off every 7 minutes saying that it has found a virus in the c:\windows\Temp folder. So I tell avast to delete it, and then 7 minutes later it happens again with a different .dll in the same folder. In the end was getting annoyed so turned off my wireless and started Malwarebytes and now it has stopped. Would this be the same virus trying to download itself again or different ones?

    Probably the same one, generating random dll names.
    Windows 7 x64 // i5-3570K // 16GB DDR3-1600 // GTX660Ti 2GB // Samsung 830 120GB SSD // OCZ Agility4 120GB SSD
    Windows 7 x64 // Phenom II 955 // 8GB DDR3-1333 // GTX460 1GB // Corsair Force3 120GB SSD
    Samsung Galaxy S4 GT-I9505

    Virus could be in multiple parts, and when your AV cuts its head off, It grows another with a different file name.

    You're probably deleting the files its creating, rather than the virus itself..

    Depends what the virus is, or what Avast is detecting it as. Disable system restore and use ccleaner, to remove whats in the temp folder

    There will be other parts of it in other places on your system...

    Until you find out what virus it is, you won't know what these places and files are...

    Upload the dll in temp folder to virustotal.com and see what it comes up with..

    Can you turn the wireless back on and make it re-download the file?
