I'm at my wits end with this laptop. It belongs to one of my customers. They have next to no money so I charge them next to nothing and sometimes no charge at all. I'll get to it. Any help will be greatly appreciated.
The laptop is a Gateway MX8711. 17" monitor, 2 gigs ram (That's the max) Windows Vista 32 bit. When she gave it to me it was very unresponsive. I figured viruses so I ran Malwarebytes-AntiMalware. It found and removed several hundred PUP's and some Trojans. It still ran slower than usual so I ran a full scan with Avast. It found more PUP's and sveral more Trojans. One of them was MBR Cidox-C. I had clicked on 'clean' before I saw that one and because of that, the MBR was wasted and forced a reinstall of Windows. I don't know what other more nasty viruses were on the laptop.
They never had recovery disks but the Windows sticker is legible enough to use for activation. I made them a Vista 32 bit install disk and one more disk for one driver that doesn't get installed. It's for the card reader. I reinstalled Windows, activated it and then installed Avast. Next step was to install all the Windows Updates. Due to what happened, I also tried not installing Avast, but that didn't work either. When I try to get the Windows Updates it just keeps saying 'Checking for Updates'. I let it run for over an hour and it never changed. I must have reinstalled Windows 4 or 5 times and it just keeps checking to no end. I tried "Get updates for other Microsoft products" and it fails also. When I installed Avast, it got to the very end and then hung. I was finally able to get it installed, but the Web Shield is turned off. If I turn it on, it shuts right back off.
With Windows hanging on 'Checking' and Avast's Web Shield refusing to stay on, I again thought...viruses. But it was a fresh install so that shouldn't happen. I ran scans anyway and they came back clean. I also ran TDSS Killer, Malwarebytes Anti-Rootkit and Combofix. They all turned up nothing. So why can't I update Windows and turn on Avast Web Shield?
I've made sure the Services and the dependecies were running but that didn't make a difference. Here are pages whose fixes I've tried to no avail:
Tried all of those and nothing helped.
I won't put them all up because you get the drift. I tried the Windows Update Readiness Tool etc. I even burned a new Vista install disk just in case that was the problem but the outcome was the same. If not for Avast having problems I'd figure it's strictly a Windows peoblem, but with Avast screwing up, I'm wondering if the problem is deeper. I installed a brand new hard drive that I had and that didn't help either so I know it's not the hard drive. This is why I'm at my wits end. I can't for the life of me think what could be wrong. Is it possible the BIOS is infected? Can that even happen? I know the BIOS can become corrupted but I've never run into that problem so I wouldn't know the symptoms. The laptop has the latest BIOS but if that's the problem it can always be reinstalled, however; I can't find instructions on installing this particular BIOS and we all know that a bad BIOS install can more or less brick the laptop.
