I started getting all kinds of problems with my (old) laptop that up until this point had been running fairly consistently. Avast didn't/couldn't find anything so I ran these malware scanning programs:
1. Spyware Blaster
2. Spybot Search & Destroy
3. Kaspersky TDSSKiller
5. Zemana AntiMalware
6. Adware Cleaner
7. Junkware Removal Tool
Some of the above found various adware, PUPs etc, all of which were quarantined and then removed/deleted using the appropriate procedures. But was still experiencing problems...Avast started hanging and being non-responsive even after reboots, so decided to uninstall, and reinstall, but when trying to reinstall it gave this message:
‘Another antivirus program has been detected – AntiVir Desktop – It is strongly recommended to uninstall AntiVir Desktop before continuing with your Avast installation. Running 2 antiviruses at the same time will slow down your computer and might make it unusable.’
I definitely didn't install this, and couldn't find it in any program folders, or anywhere on the PC so Googled AntiVir and learned that it was malware…and additional searches brought me to the Bleeping Computers 'Antivir removal - Self Help Guide'. I followed the guide and ran RKIL and Malwarebytes and then tried reinstalling Avast again...but got the same message about AntiVir.
I'm at a loss for what else to do and seriously frustrated that all previous steps taken have not managed to sort the problem...any advice will be really appreciated.
NB I am running an old Dell XPS (10 year) with Windows XP. It shipped with an Intel Core 2 T2300 CPU - after Windows stopped providing support for XP, I bought a new HP laptop with Vista...I haven't upgraded to Windows 7 or anything newer...and when the HP died on me, I fired up the old Dell XPS, updated the BIOS, upgraded the CPU to an Intel Core 2 T7200, and updated all the drivers that the Dell support page was showing as newer than already installed, then after all was running fine for a few weeks, transferred/copied (disk image) all to a partitioned larger disk. I was never really impressed with Vista and so thought I'd try learning about Linux/Ubuntu, so installed Ubuntu on the other partition of the disk and set it up to 'dual-boot'...and all was running fine for a few weeks until the last few days when all sorts of problems with my mouse, my wired connection (I rarely use wireless...too nervous with XP), and software started behaving weirdly...so it would appear that I've been caught out by the now limitations of XP...but I still prefer XP as it all seems so sensible and navigable to me. I realise that at some point I'm going to have to bite the bullet and purchase a more modern computer, but if I can squeeze some more mileage out of my Dell...
By the Bye, Ubuntu is still running fine with no problems at all...and I do go online with it too.
PS sorry for this post for being so long!
