As the Consequences: computer is slowed down,its impossible to launch the applications a few times, operation of hard drives in new windows, can not display hidden files ... So thank you to anyone for helping me out.

This is shown by avast

You can also try Noob Killer. Download it. You can do a 8-X Kill which will clear all the malware or you can it delete the file yourself. It has got many options. Try it.

Go for a full scan with the following softwares:

* *www.superantispyware.com/download.html
* *www.emsisoft.com/en/software/free/

Also make sure that they are updated to latest definition files and go for Full System Scan.

Else

You can always try Online Scanning. Here's the list of best Online Scanners: *mrintech.com/5-best-online-virus-scanners-you-can-use

@Davidboon: do tell us what you used to get rid of the infection.

At last i got rid of the virus but still i have to open all my partitions using the explore option instead of double click . only my system partition is accessible with double click .

i just did a boot scan of all the partitions using avast and deleted all suspicious files .
and use malwarebytes too.

Enable 'Show hidden files and folders' and also the 'protected system files' from the Folder Options........go to each Disk drive and delete the file 'autorun.inf' manually. And Restart.
