Anti Virus/AVG
AVG Free provides you with basic antivirus and antispyware protection for Windows and is available to download for free. A while back AVG upgraded to the 8.0 version. So, if you're still using 7.5 you may be in some trouble as the old version may run scans but is not up to date.
We have been using AVG free for some time now and have had very good luck with it. Not only a virus protection but this software will check for rootkits and has some capabilites for spyware protection as well. The best part, AVG is not as bulky and full of junk you don't really need like some of the more popular pay-for brands.
