I download a file from the internet to my disk. When I open it asvast said FileRepMalware and delete it instantly (not moving into quarantine zone). I think that my pc has infected virus. And now sometimes avast just pop up and said some file of mind has been infected as FileRepMalware. I don’t know what’s that do, and it just delete it instantly again. I have to turn the shield off now. Anyone have an idea to fix this ? I can’t just wait to let the avast (or actually virus, i don’t know) keep deleting my documents. Thank you

The “virus” seems to be infecting the executable file only, this makes me starting to suspect this virus as Sality.
I’m doing your solution now, hoping it’ll work. Thank you
I saw no indication of sality, but if you wish we will check that out next
Ok this is the fix log file
I’m running AdwCleaner and hope this will work.
Thank you for the result, just glad to hear my computer not infecting the sality
Please check that deep, I’m still sad because some of my important documents are gone
And a question please: I’ve seen, the other virus avast will block it from running and move it to the chest, but, why with this “virus”, avast instantly delete the file without any asking.
This is the log for AdwCleaner
Now can i turn on the avast shield ?
Filerep means it is a new or rarely used file that Avast has no information on
This programme will generate a zip file which I will need. This will either need to be uploaded to a file sharing site like mediafire https://www.mediafire.com/ ar placed in your public dropbox if you have it for me to collect
