Re: I have Noticed
I have used most anti-virus programs at sometime or other and find that most of the well known ones try to control your computer. I now use Microsoft Security Essentials and as of yet found it very good with no problems being caused by it.
Kaspersky, Norton, McAfee, AVG, Trend, Bullguard all tend to either over do it and block things that you dont want them to block due to them not being trained properly by the user.
I use Malwarebytes anti malware and CCleaner, both of which I find very good as long as you update them regularly.
I also spend some time cleaning out orphan files from my register, not recommended unless fully understand what your doing.
The problem with letting your computer remember your user name logins etc, is that should your computer be hijacked then all your details are there to be used by others.
To stay completely safe I do not recommend letting your computer remember any of your details. It only takes a minute to enter them anyway.
