An antivirus software alert could be viewed as a good thing, after all if you have used a computer for a number of years and never received any Antivirus software alerts could this possible mean that it’s not working properly?
As a safe guard it’s better to run two types of scan, one using a real time scanning program such as Microsoft Security Essentials or AVG, and another scan once a week with a program which only scans when you manually run it, programs such as ESET or Malwarebytes are both very good.
In addition to this any antivirus software alert needs to be noticeable, but not so much, or persistent enough to be an annoyance.
Having unobtrusive antivirus software deals with any malware or viruses it finds itself, you might have to do one click to device what to do with the file, but that’s it.
It should not interfere with you using your computer, stopping you doing things, thinking it knows better than you what’s best for your computer; any antivirus software alert should be small and concise, nothing more.
There are some very large antivirus programs on the market that literally overload us with information, use more system resources than many applications, and really do slow down many computers.
As we said above good unobtrusive antivirus software should be all you need, after all we want to just use a computer to do what we want and not spend all of our time dealing with and managing any antivirus software alerts be them real or just some paranoid piece of software.
Currently my own personal favorite is Microsoft Security Essentials, its antivirus software alerts are small and not popping up every few minutes; and who would know better than Microsoft which files are infected or have been replaced.
On top of this it’s totally free, nice one Microsoft
