Welcome to GTG.
If you have a fast internet connection (broadband), run an online virus scan at TrendMicro
http://uk.trendmicro...call_launch.php. Just follow the instructions on the site to run the online scan. If any viruses/trojans are detected, try to delete or clean them in that site. You may use Panda ActiveScan also at
http://www.pandasoft...ucts/activescan. Otherwise, make sure your antivirus program has the latest definitions and run a full system scan.
Read the first link in my signature and post your HijackThis log here when ready.
Also give me this log:
Let's use a program to scan for any trojans that may exist. Download TDS-3
http://tds.diamondcs...p?page=download. Learn how to use it at
http://tds.diamondcs...?page=easytouse. Make sure to update it after you installed it. You can get the manual updates at
http://tds.diamondcs...php?page=update. When you launch the program, it will scan your memory for running processes. This will take less than 30 seconds. Next go to 'System Testing' on the menu and choose 'Full System Scan'. After that's finished, post the log file by selecting everything on the top pane (select from bottom to top). If any alarms are found, it will be listed in the bottom window. Please copy and paste that here also if it applies. If you have problems copying the text, look (or search) for a file named scandump.txt and see if that has the alarms - post that here.
