MODS: I apologize for bumping an old post. But I have valuable information to share that can help others. I don't do this often.
When getting Anti-virus software go to av-comparatives.org and look at their test results. They are the only independent testing company for anti-virus software. It takes a while to get used to finding the information but it gets easier to understand as you read more.
Please be aware that having more than 1 active agent software is not healthy for your computer.
An active agent software is easy to identify. If it is automatic and you do not have to press scan now, then it is an active agent.
If you have to press scan now then the program is an on demand scanner.
I reccomend having two anti-virus programs on your computer. 1 of them should be an active agent and the other an on demand scanner.
Here is the reason why: Each program has a database it compares your files against known viruses. The companies do not share their list of viruses with other software providers in most cases. This means that 1 software may have found a virus another 1 would have missed. So read AV comparatives and choose a quality active agent scanner. I like F-Secure or Microsoft Security Essencials (free). Then find a good on demand scanner, these are always free. They won't be listed on av comparatives. I would reccomend Bit defender Free edition.
If you get an active agent software which is not microsft security essentials, then a good on demand scanner is called "microsoft security scanner". It expires after 10 days but can be re-downloaded.
Also you may want to check your computer security now. This is a website that will attempt to hack into your computer for testing purposes only. It is not an actual attack and they are only trying to find out what ways your computer is vulnerable.

If it doesn't work then go to
www.grc.com - services - shields up and test a few settings.
Here is my current setup.
F-Secure as main active scanner.
Malwarebytes Pro as an anti-malware scanner
Microsoft security scanner as my on demand scanner
I also use another service to further protect myself but it was mentioned in the security post already. I have my reasons for not wanting to name it.
If you have questions i will attempt to help you find a suitable program for your needs. We need to watch out for each other in this community and I'm willing to help. Excuse the spelling and grammar.
