ITS very much annoying. please help me to resolve this problem.
I have scanned my system in safe mode but still i couldnt resolve.
avast continues to pop up warning.

Try running the following programs. With HijackThis,choose ’ scan and save a logfile, copy / paste the log here.
Then run MBAM and SAS, and post their logs as well

Also clean your temp files with Ccleaner http://filehippo.com/download_ccleaner/

Clean your temporary files. You can use CleanUp or CCleaner for that.

It will be good if you download, install, update and run MBAM.
If any infection is detected, better and safer is send the file to Quarantine than to simple delete them.

i have scanned my system with HIJACK THIS! and following is the log file generated.
