I was infected with a virus (Win32.Jeefo) and I found a tool to remove it. My problem is that this virus infected some files in the win\sys32\driverstore\filerepository and now I cannot delete them. But my biggest problem is how did the virus infected the files if I cannot delete them? And how can I login with the administrator account if I forgot/did not set a password for it? thank you EDIT: windows defender doesn't detect it and firewall and UAC are off. I have Vista Bussiness x86.

Hi, I suggest we first try to remove the infected files under Safe Mode and then update your anti-virus program. Step 1: Boot the computer into Safe Mode to delete infected files Perform the following steps to go to Safe Mode.1. Reboot the computer. 2. When the Starting Windows screen shows, press F8. 3. Select Safe Mode and press Enter. 4. Log on as Administrator or user account that has admin privilege. 5. Does this issue occur in Safe Mode? Can you delete the virus infected files in Safe Mode? (NOTE: Safe Mode loads the minimum number of required basic device drivers and system services to start the system. Programs located in the Startup Program group are not started. So this will be very helpful for us to narrow down the root cause.) Step 2: Update your anti-virus program Please update your anti-virus application's virus database and perform a full scan on the whole hard disk to ensure that the system is not infected. You may also use some of the online removal tools located at: http://security2.norton.com/us/intro.asp?venid=sym&langid=us http://vil.nai.com/vil/stinger http://www.trendmicro.com/download/tsc.asp You can also contact your antivirus vendor for assistance with identifying or removing virus or worm infections. If you need more help with virus-related issues, contact Microsoft Product Support Services. For support within the United States and Canada, call toll-free (866) PCSAFETY (727-2338). For support outside the United States and Canada, visit the Product Support Services Web page (http://support.microsoft.com/?pr=SecurityHome ). By the way, Windows Defender does not remove and fix virus problems. If you lost the built in administrator and there is no other account available, I am sorry to say you have to reinstall Windows Vista to reset the built in administrator password. I hope this helps.

Hi, I'm sorry for answering so late, but after the first couple of day passed and I saw no answer I took the matter into my own hands and this is how I solved my problem: 1. took ownership of the files 2. added my user with full rights 3. deleted the files All this was done with my account, not the administrator account (which is disabled). thank you for your interest, Lucian Coman

Thanks for your response and sharing, Lucian Have a nice day. Best Regards, Robbin Meng
