I recently had a PC tower 'die', and had to revert to using my back-up laptop.
I have had a week getting used to Windows 7 on that laptop.
My son returned my repaired tower today. He was unable to save any data on it so it is 'empty' except for the things he put on it for me (Windows7, Firefox, Adobe Reader)
When I mentioned that I would download AVG he said that
Microsoft Security Essentials would be better. He explained this by saying that Microsoft are aware of the shortcomings of their systems and produce solutions in updates. They are hardly likely to advertise any shortcomings they detect, so other producers of virus detection systems are less likely to be aware of faults than Microsoft themselves.
Another security issue we discussed was password entry on Startup.
I am the only person who uses my PCs so I found password access a nuisance and removed it.
He said that this was foolish because it meant that hackers could get easy access.
So I have restored the password on my laptop.
Then we discussed passwords - It seems most of mine are too easy to guess - they should have
symbols, letters and numbers.
My son has a degree in Information Technology and his job is development/maintenance of the computer systems at Manchester UNI - so I do give what he tells me a lot of credibility.
I now will be busy 'filling up' my two PCs with the bookmarks I lost, and all my music from CDs(which I wisely kept). The only thing I saved on a memory stick was banking docs.
