After becoming very slow I ran a diagnostic program Trand Micro Housecall, it took seven hours to run.
I identified several trojans and a backdoor entry, all of which I was able to get rid of.
I then installed AVG antivirus (after deleting F-Secure) this program then found another 11 problems, some Malware, some trojan plus adaware
all items were sent to virus vault. Ran scan again still found more.
With all these unwanted items in vault computer has speeded up alot.
The problem I have now is when signing onto Internet Banking I am asked for the usual, sign in name, password and secuity password, 3 letters of a word or phrase in drop down boxes but also asks for this information to be written in full in another box. I have checked with the bank this is not correct. It's not just one bank account it's the same on others.
Have I got something still lurking in my computer trying to get hold of my personal information?
Sorry it's such an essay but thought knowing what I've done might help.
Look foward to your reply.
