Dangerous E-mails
I've noticed a sudden increase in the number of bogus invoices, account statements and the like - all looking as if they could be genuine (but from firms I've never dealt with). From none over several months, I'm now receiving a dozen or so each day, to various different addresses including some that have hitherto not been spammed.
Most contain attachments that are either Word documents or Excel spreadsheets, with hostile macros which I'm sure would run and enrol my PC in a Botnet or worse. I've not tested that bit.
Time to check the anti-virus is working, and to be extra careful, methinks.
