any feed back will be greatly apprecated.

 

1) If you want to pay for software then F-PROT (AV) has a 5-user license. Norton IS 2008 also has a 5-user license available.

2) Try one of the big 3 free AV's - Avira, Avast!, AVG

 

F-prot is available for 5 computers for $29.00.

thank you I will look into these and see what is best protection of them.

 

Try to keep most everything on your PC's up to date. Windows, Java, Flash player, E-mail clients, browsers etc. are constantly updated due to vulnerabilities found in them. See the link in my signature to do a check online with each machine and then update any program that the scanner detects as vulnerable. Sometimes it's a pain to keep up with them and some programs like Java you have to manually uninstall the old versions. Flash Player also has a removal tool that is recommended to run before installing the new version. Your reward for all this work is a system that when running online and you happen to stumble into malware, it shouldn't be able to do it's nasty deed because the holes it uses to do its work is patched/fixed. This doesn't protect you 100%, but it gets you a big step closer.

I would just run one of the free AV's that EliteKiller mentioned until you could buy a "family pack" of whatever security software you like. Many of us have or are running free AV's and they are fine. Avira has the highest detection rate out of the three while Avast is the most complete and adds spyware protection.

If you want an on-demand anti-malware/spyware program, both SuperAntiSpyware (SAS) and Malwarebytes' Anti-Malware (MBAM) are good. By "on-demand" I mean they don't provide real-time protection but they can scan your system or files for spyware/malware. They also offer realtime (active) paid protection versions.

Oh, I almost forgot. Hi and welcome to Wilders .

Edit: Also, please have a look at this great thread. https://www.wilderssecurity.com/showthread.php?t=206805

 

If you want protection for personal/home use, I would suggest to look at AVG, Avast, Antivir, Comodo and PC tools. All of the above offer free security tools for home users (comodo offer free tools for professional use too).

If you want to buy a product sunbelt has an interesting offer:
Annual site license subscription protects all PCs in single household (protection for unlimited PCs)

They have a very nice beta antivirus/antispyware that will be released in a few months. https://www.wilderssecurity.com/showthread.php?t=202584
