Hey folks, Recently my computer infected the Security Toolbar 7.1 virus and appeared exactly the same symptoms as the previous one posted on Techspot named "Cannot uninstall Security Toolbar 7.1". I have reinstalled Windows XP for 2 times (formated), but everytime after I used it for couple hours after new installation, the nasty Security Toolbar 7.1 comes again. I found that there will be a 'outerinfo' appears in the Add & Remove Program list after I installed some software such as winrar, Adware, NOD32 Antivirus, and the Catalyst Control Center (all previously downloaded and stored in the external hard drive). Then I tried to remove it with NOD32 and Adware personal, but even i did remove outerinfo, the Security Toolbar will then infected the system. And it can't be removed by NOD32 or Adware. Now, the third time I reinstalled my system (formated), I don't want to get into trouble with Security Toolbar 7.1. Should I follow the Viruses/Spyware/Malware, preliminary removal instructions step by step? I don't want to install that many anti-virus/spyware softwares in the same system. what else I can do? HELP PLEASE!! Attached is the most recent HiJackThis scan log. Thanks a lot.
