Receiving alerts from AVAST about every 5 mins or so that a trojan has been found: "Win32:Bredolab-AQ [Trj] found in C:\Windows\Temp\x.tmp" ...always new x.tmp created

[Vans]

I receive an alert from AVAST: Win32:Bredolab-AQ [Trj] found in C:\Windows\Temp\*.tmp (always new *.tmp files created) about every 5 minutes...
Have run a full system scan with AVAST, Windows Defender and Spybot - Search&Destroy (all up-to-date with latest virus/malware databases). Nothing is found by any software!... only these AVAST alerts popping-up every 5 minutes or so.
One other symptom: when I "google" something, clicking on the results will lead to URL redirection, i.e. not going on the result URL.

Please find attached the log file generated by Kaspersky Virus Removal Tool' system information collection option.

I am desperate as my RAID crashed recently (doubfully related though, because of time of symptoms).

Thanks in advance for your help folks!

You have made changes to the hosts?

205.133.7.3 IM2COOL.COM
24.201.245.200 ftp.videotron.ca
216.113.122.74 ia-cnnu-bb04-pos5-0-0-cpe074.vtl.net

1. Please, disable System Restore and antivirus (if you have).
2. Execute the script in AVPTool:

begin
ClearQuarantine;
ExecuteAutoQuarantine;
RegKeyIntParamWrite('HKLM','SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer','NoDriveTypeAutoRun', 221);
RegKeyIntParamWrite('HKCU', 'Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3\', '2201', 3);
RegKeyIntParamWrite('HKCU', 'Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3\', '1201', 3);
DeleteFileMask('%tmp% ','*.* ',true );
ExecuteWizard('TSW', 3, 3, true);
CreateQurantineArchive('C:\quarantine.zip');
RebootWindows(true);
end.

After restart upload file C:\quarantine.zip, by link http://virusinfo.info/upload_virus.php?tid=58838

3. Attach a new avptool_syscheck.zip.
