General Computer Support / Re: Access Denied problem still not fixed - Win 7 - Adding new USB drivers
« on: August 01, 2014, 05:11:15 pm »
Success! Thanks to Shane & Jraju,
But, things did not go smoothly. First, I added a new user account and gave it Administrator authorities as Shane requested. Nothing changed, new USB devices were still not recognized by Windows 7 Professional and it still would not restore to any earlier restore points. I continued to get the Access Denied error message when attempting a driver update using Device Manager. So, I deleted the new user account.
Next, I set a restore point and then ran Norton's registry cleanup. I use Norton anti-virus protection. Still no change.
Next I had Norton run a full system scan. Norton found nothing. Again, no change.
I then went to MalwareBytes.com's website and downloaded the free version of MalwareBytes. Next I disconnected from the internet (and WiFi & Bluetooth) and turned off all antivirus software and firewall software. (I am not on a network). I opened the folder and installed and ran the MalwareBytes software as Jraju suggested. MalwareBytes discovered several Trojan's and 20+ PUD files. I instructed MalwareBytes to "quarantine" the suspected viruses. I am attaching a text file of the MalwareBytes scan results for reference. MalwareBytes was not up to date (so it could not update itself) as I was disconnected from the internet but I performed the scan anyway.
Again, I attempted to connect two new USB devices (a flash drive and an external drive enclosure) and Windows 7 Professional would not recognize them and gave Access Denied errors when forced to look for and load drivers using Device Manager.
I then powered down the computer completely by unplugging it, removing the battery, pressing the power on button many times and letting the computer sit completely without power or batteries for 20 minutes. Then I started the computer and ran the ck files & ckdisk from the Tweaking.com control panel (Step 2 I think). Both came up clean. Again there was no improvement in the USB connection problem.
Next I set another restore point and then attempted to do a MalwareBytes scan from the Tweaking.com control panel but got an error message, saying MalwareBytes would not run. So, I turned my Norton anti-virus and firewall software on again, reconnected to the internet and exited Tweaking.com. I activated MalwareBytes and asked it to update itself. After it had updated I again disconnected from the internet, disabled my WiFi and Bluetooth and shut down my anti-virus and firewall software. Then, I had MalwareBytes scan my system again. It again found what appear to be the same Trojans and PUD's as before. I am attaching a second text file with the second scan results for reference.
Then I re-activated Tweaking.com and again went through the first three steps, including the ckdsk and ckfile options. Everything reported OK. Then I had Tweaking.com check and repair my system (Step 4 I think). After the repair and before I reactivated any antivirus or firewall software, or connected to the internet, I attempted to connect a new USB flash drive. Initially, Windows 7 Professional gave me the "error" tones when I plugged in the flash drive. It also did not show up in "Computer". I next went to "Management" and it did not show in Disk Management. I want to Device Manager and it did show there, but with a warning Icon. I could tell Windows was trying to do something though as Management kept refreshing itself. After about a minute of this I finally got the long awaited message "New Device Found" and in another minute or so drivers installed automatically and the USB device worked normally, appeared normally in "Computer" and showed properly in Disk Management. Finally success!! I don't know why it now takes Windows so long to recognize a new USB device or load the drivers, but thank heavens it's working again. This used to be a quick process any time I plugged in a new device. But, at least it is working again!! My external drive enclosure is also recognized, even though it takes much longer than before.
The last thing I needed to do was get Windows Update to work again. I set another restore point and told Windows Update to check for and install updates. It did, successfully, for the first time since the USB problem manifested.
The MalwareBytes scan appears to have found a few things that allowed Tweaking.com to then come in and reset the permissions in Windows so it would again recognize USB devices, load drivers, update and restore to prior configurations.
Today I bought a new hard drive of the same size and cloned my now fully functional computer's hard drive. I put the clone back in the protective wrapper, back in the box and in a cool safe place. I will never allow myself to get into this position again. Nor will I depend on Windows Restore to work!
Thank you Shane & Jraju, and thank you MalwareBytes.com and Tweaking.com. My problem is solved.
One last question: The most it appears you can do when MalwareBytes finds a virus is "quarantine" it. I want to DESTROY it. How do you do that? I want these virus files gone out of my computer, not simply quarantined!
Sincerely, Doug
