Sorry for the length of this in advance,
I am a self taught techie and have been building and fixing pc's for around 15 years, specialising in virus and malware removal so I would say that I am reasonably experienced but the other day I came across a new problem which someone may be able to help me with.
A friend asked me to take a look at his sisters hotels " backup " computer and just see if I could update it and clean it up, this machine had been sitting under a desk, unused, in the hotel for around three years as they use a laptop day to day and this Tower had been their previous machine.
Dual core intel 1.8, 2Gb ram, running Vista ( I know, I know ).
There was a ton of customer accounts and other stuff going back years, Documents, Pictures, VAT stuff, Excell spread sheets, emails etc, I offered to back it all up and flatten it and put Seven on it but they were firm that they wanted it with Vista ! I even suggested Another hard drive with seven and slaving the current drive, but again no !
Standard stuff really, all the usual malwares and half a dozen trojans, etc.
They had an install of avg from around 2010 which I noticed had never been ran since its first scan, although it had been updated in 2012, again, ran once and then never since.
So, as allways, I ran malwarebytes which removed most of the junk and problems and then decided to remove the " old " avg and install the latest version.
So I ran the windows removal from Add/Remove programmes and not that unusually, it wouldnt uninstall.
No Bother, installed Revo Uninstaller and tried to remove it with that, it ran fine and removed everything related to avg.
................ or so I thought.
After a restart there was no trace of any avg anywhere, so I then started the installer for the latest version and it failed, again, not unheard of but not common.
As it happens, I have a collection of specific antivirus removal tools (thanks Grinler), including an avg remover, which I ran and it appeared to be finding and removing loads of components.
After rebooting I tried again to install from another fresh downloaded installer (downloaded on a seperate, different computer).
Same thing again, the install failed.
It now became a matter of principal.................... this wasnt going to beat me.
I ran Revo again and there was no trace of any avg so I decided to install Avast Premium which I also like.
While it was installing it told me it had found another antivirus on the system and would i like to remove it, obviously I said yes and again restarted and again it ran and told me the same thing at this point i clicked the option to carry on the install.
It all installed as normal and I updated it and ran a full system scan which found a few pups and removed them and the system now runs much faster and is as working as good as any other machine of its age and specs, better in fact.
Anway, Job Done ............................You would have thought.
There, on the taskbar was the avg logo !
The system is working perfect, Avast runs perfect, Revo doesnt find any AVG traces, but there it is, sat on the taskbar mocking me.
It doesnt show up in add/remove programmes, it doesnt work if you click on it, nothing happens if you right click and try to turn it off, fully or temporarily.
So, as they say, "If it aint broke, dont fix try to fix it".
The machine is running fine but it is still bugging me.
Any and all Ideas welcome and appreciated.
