I read as much as I could about this trojan/virus on these forums. The "Cannot uninstall Security Toolbar 7.1" thread is apparently closed so I did not attempt to post to it and am trying to start a new thread. I let a young friend use my lap top and within a minute or two he had picked up the Security Toolbar 7.1. Fortuntately he told me about it immediately and I have not contacted any of my usual websites. I use the internet a lot for banking and other sensitive activites and from I have read this trojan/virus can create serious problems. One poster recommended a complete disc reformat and reload of OS and software. Unfortunately my HP Pavilion laptop did not come with any installation cds. There is a partition on the harddrive with backup of some of the non-OS software. I am not able to restore to any of my previous restore points. All restoration attempts fail. I assume the trojan is managing that. I scanned with Spybot. It found a few problems and fixed them, but it did not fix the Security Toolbar 7.1 problem. I am scanning now with AVG. (By the way, I also have a pc and am using it to do this work.) I read an impressive and convincing post here by AntiSecurityGirl, from November 2007. Has anyone followed her advice and successfully gotten rid of this trojan? Anyone with any other pertinent and useful information about getting rid of this thing, please post. Anyone know how I get installation cds from HP for my laptop without a major hastle with them. I am willing to pay for them. Thanks to you all.
