At the moment everything seems to be going wrong with my computers!
I have a Packard Bell desktop which is getting a little old now, but recently got a virus or something on it which encrypted all my files and told me to buy their decrypter if I wanted to get any of my files back. Luckily I also have a Dell laptop which is the computer I mainly use so I had all of my important files on there. So I decided to do a destructive recovery of the desktop computer. Since then it was working fine.
Only a few weeks later my laptop started freezing for no apparent reason. It is now at the point where it lasts for about a maximum of 10minutes without freezing. Originally I thought it might be overheating, but now i've suspect the motherboard or something inside isn't working properly or it has a virus or something. It also has been very picky about whether or not it wants to accecpt usbs. I tried saving my files to usb and it would work for a little bit but then stop transferring and I would have to pull it out. Gradually I was able to transfer most of my files back over to the desktop so I would have a second copy.
This was working fine until the other day the desktop started freezes whenever I plug in a usb. Although, if I plug in the printer usb cable, it is fine. I have attempted to do system restores for both computers but it comes up with this message 'Changes made to drive(s) E:\ C:\ after this point cannot be reversed because the drive was either excluded from system restore monitoring or was turned off or removed'. Also, now my laptop keeps coming up with 'usb not recognised' if I plug in a usb
Both of the computers have norton antivirus on them and I have run multiple other virus scanners all of which have detected nothing! I think its a bit odd that both of the computer have almost identical symptoms so maybe one has infected the other whilst i've been transferring files?
Any help would be appreciated and thanks in advance
