My computers are running normally and carry appropriate virus /malware protection (Avast at the moment) The other day I was typing something into "word" on my laptop. I noticed that when typing in a word, the first letter would appear and then there was a delay before the rest of the word appeared. A thorough Malwarebytes scan was immediately initiated and a trojan was discovered on the d: partition of my hard drive. Now this partition is only used to store windows recovery files and is thus hardly ever accessed. How did it get there? Anyway, said trojan is now deleted and normal service (without delays) has been resumed. In recent months I have discovered several trojans on my machines - they are quite sophisticated - I had one recently which was preventing my antivirus and antimalware software from updating itself. It was not however preventing downloads thus I could download a copy of malwarebytes which was fully updated and which found and destroyed the trojan. If Saab will permit me a brief plug for this free software - it often publishes update files more frequently than daily and it has sorted out my malware on several occasions - not that there is not other excellent free software for this purpose out there.
P.P.
