After updating my antivirus today I got this warning:
http://i25.tinypic.com/2dvrc5.jpg
Avast(home) deleted the file but it is reappearing. I don’t know why avast is not deleting or blocking the source of this file. Please tell me how to remove this virus permanently.
Download malwarebytes http://filehippo.com/download_malwarebytes_anti_malware/
After you have it installed,update it and run a full scan.
If it finds any infected items,remove it.If the program ask for you to restart your computer,please do so.
Then post back a log from it
If it keeps coming back, there is likely to be an undetected or hidden element to the infection that restores or downloads the file again. What is your firewall ?
If you haven’t already got this software (freeware), download, install, update and run it and report the findings (it should product a log file).
Don’t worry about reported tracking cookies they are a minor issue and not one of security, allow SAS to deal with them though. - See http://en.wikipedia.org/wiki/HTTP_cookie.
Note:
If either find files that they state are infected, first copy the file to the avast chest User Files section and send to avast to improve overall detection.
Add the file to the User Files (File, Add) section of the avast chest where it can do no harm and send it from there. A copy of the file/s will remain in the original location, so you will need to take further action and can remove/rename that (allow MBAM/SAS to remove/quarantine it/them).
Send it from the User Files section of the chest (select the file, right click, email to Alwil Software). It will be uploaded (not actually emailed) to avast when the next avast auto (or manual) update is done.
Thanks to ESET Smart Security…
It has completely removed the virus…
Thanks to forum too…
