access to malicious site blocked. Also, Suspicious file found

Hey frnds, I am novice regarding computers.when i open my laptop,a message comes "Access to suspicious site (site name mentioned) blocked. I have Avast 4.8 pro. Then after some times another window opens with heading “Suspicious File Found!” It tells:-
A suspicious file has been detected(using heuristic method).This may be a sign of malware infection.Please allow the site to be submitted to our virus lab for analysis.

File name: C:\tgt.exe
Type: rootkit: hidden process

Please tell me what to do so that all this problem goes away. I will be thankful if u tell me exactly the steps since i dont know much .Thanks,
Sumit

There should be an option to send to avast for analysis (this should be checked automatically) allow it to be sent. The recommendation on the alert window is Allow, which with this heuristic detection is best.safest to be used.

I would say it is suspect too and there are some google hits to confirm that, I would suggest that you check the file out.

You could also check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner and report the findings here the URL in the Address bar of the VT results page.

It may be worthwhile to try some other tools:
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.
