=========
may i suggest this program before you buy Kaspersky 2009 .
==============
Download Malwarebytes' Anti-Malware

(http://www.majorgeeks.com/Malwarebyt...are_d5756.html) to your

desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure to checkmark the Update Malwarebytes' Anti-Malware and

Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
post the log back here.

also suggest this program for after you use malwarebytes ,run its cleaner and registry cleaner functions . www.ccleaner.com

I would also like to mention here that you have said that you installed Trendmicro and then removed it...how did you remove it? Did you actually UNINSTALL it or just delete? Make sure it was uninstalled. One should never have more than one antivirus program running on the computer.
Then you said you installed avira antivirus and it DID find 34 infections. So it IS working. Keep it. It is an excellent FREE program, no need to install another.
Follow caperjack's instructions. You can also download Malwarebytes' Anti-Malware directly from their website also.
Be sure to reboot the computer AFTER running MBA-M and removing everything found.

Also download and run HiJackThis and post that log here once you have finished all other instructions
