So last summer I got a virus on my laptop. I got rid of it by pressing the required button at start up that reintalled windows vista and resetting my laptop to factory settings. But now I have another. First of all I can't reset my pc the way I did before, It just beeps loudly. I'm pressing the right button too! The virus I have now makes it so I cannot go to any website. I can connect to the internet but every website and search I try to access just comes up with a white screen and says its loading. But even after an hour of waiting it still does not load. I use opera as a browser.What used to happen is every website I clicked on would come up with some add site called abnow. All I had to do was copy the link of the website into the search box and it would bring me directly to the website. But now no websites will load. I have also had this problem of just about every program I install will have this error when I try to use it: "Windows cannot access the specified device path, or file. You may not have the appropriate permissions to access this item." I am the only person who uses my laptop and I am the administrator, so I should have permission to use it. I also looked at the permissions of the files and I had permission to use them. Most programs that do this are ones that I install from disks. All of the programs effected never had this problem until these past couple of months. I had to uninstall all of my antivirus software and now I can't install anymore. I can't download any. Norton requires me to activate through the internet. Malware bytes has that error above now. But there is this folder that I found in C:\Program Files\. I have no idea what it is and I have idea where it came from. Its called RelevantKnowledge. It has a file in it with no name and no file type. Its size of it is: 105 kb. If I try to delete it nothing happens. If I try to delete RelevantKnowledge the folder its in I get this error. "error 0x80070091: This directory is not empty." I don't see how that is a good reason not to delete it. I have deleted directories that are not empty before. Can someone help me? These are my pc's specs: CPU: AMD Turion Dual - Core RM - 70 2.00 GHz RAM: 3.00 GB OS: Windows Vista Home Premium, 32 bit, Service Pack 1 Model: HP G60 Notebook PC GPU: NVIDIA GeForce 8200M G Please help. Thanks in ahead.
