*sigh* Yet again I turn to the gods here for divine intervention into my technological meltdown. I didn't come here when the problem first reared its head 3 days ago because I didn't want to be a pain. I'm now under water with my ignorant attempts at tech fixing and increased problems a hundredfold. Thank you so much to everyone who has helped me in the past and I apologize for my once-a-year crises.
Dell XPS i7 purchased in 2012 running Windows 7.
I'm staying with friends for several months while working out of state. Wireless internet connection is almost unusably slow (10 - 60 kbps even in the same room as the router). LAN cables in every room work on other laptops. I believe I connected via LAN when I was here before but could not do so now. So, I've spent 10 hours over the last 3 days completely mucking up my system by trying one "fix" after another. Almost all the fixes required disabling antivirus software and most created system restore points. Let's just say that at present the LAN connection is the least of my problems and I'll deal with it after I get the rest of the mess sorted.
System Restore fails (x80070005) at every point. No luck after uninstalling mbam and temporarily disabling AVG... uninstalling AVG and running in safe mode... 20+ different tries following every solution I could find on google. I called Geek Squad and get to pay $199 for them to look at it then probably wipe the drive. Alternatively, I buy a $60 portable drive to transfer files and reinstall the OS myself. While I'm too familiar with OS reinstall, I cringe because there is an email program and several other things set up for me to work remotely that I have no idea how to redo.
The system restore error says a file may be corrupted so I figured what the heck, I'll aggressively go after whatever viruses are running amok. I've reinstalled mbam and AVG. They will save but won't open even after I rename the .exe files.
