I like using paid antivirus.I've used the free trial but I always uninstall them before its runs out so I dont have to pay.I've used one in particular.How much time should you leave it before you install it again ?
Once a trial version has expired it cannot be used again. Reinstalling it will not work.
Purchase the software or use one of the many free products.
Here is the one free for ever from Microsoft.
Microsoft Security Essentials - Microsoft Windows
Legally, you CANNOT use it more than once per computer, as per the agreement with the vendor. The trial period, typically one full month, is for evaluating the program and decide if you buy it or not, but nothing more than that. Once expired, it no longer works and most times if you uninstall and reinstall it still detect it's expired. It's not possible to re-use it, legally. Technically, it's possible if you know how to lure the AV into thinking it's a new install, however, it's cracking it.
The only thing I can recommend here is to pay for the full, legal version after the trial, or stick to one of the freebies.
Since my previous posts were removed more than likely for Microsoft bashing I'll put it nicely ....
Microsoft Security Essentials is not the way to go.
Avast! 8 Free - http://www.avast.com/en-us/index
Avira 2013 Free - http://www.avira.com/en/avira-free-antivirus
AVG 2013 Free - http://free.avg.com/us-en/homepage
Any one of the three listed above will do you better than Microsoft Security Essentials.
