starship_troopers and coolbuster20 is right.. i recommend AVG or Avast or BOClean for Vista/XP why am i saying this.. look at this scenario...
Norton eats more than 200mb of RAM with XP but with Vista hmmm an additional of 100mb able to perform all its security. I can say that Norton (1 year subscription antivirus) is one of the best security tools that can surely make your system secured. With its antivirus and firewall setup for sure the 1 year subscription is not bad.. it's only $70. But the problem is, it eats a lot of RAM. If you have 2GB of RAM on your Vista system, i do recommend Norton. If it is lower, don't try or even buy it. You'll just spend your money for nothing.
Mcafee, on the other hand, has lots of network issues. After installing it, you need to download the network fixes (a patch for your network) on their website able for you to be connected to the internet. With Vista? Take a look at this...
Microsoft's Windows Vista OS has already failed a major security test.
Independent security certification body Virus Bulletin has revealed that Microsoft's much touted antivirus product, Live OneCare, is one of four similar products that failed to reach the required standard.
Eleven of 15 products submitted passed the stringent tests.
Virus Bulletin's VB100 pits antivirus packages against a spectrum of known viruses. Products must detect every virus, but declare no 'false positives.'
Vista is, of course, a brand-new product, but a Virus Bulletin spokesman said that this is 'no excuse.' He cited the lengthy delays in Vista's development, and suggested that companies shouldn't put forward antivirus tools for testing if they weren't ready.
Vista's improved security is one of its major selling point, and antispyware in particular has been boosted. But experts believe that additional antivirus protection is required.
Virus Bulletin tests products free of charge. Crucially, it does not permit re-testing, so vendors have to get their products right first time. To see the full results of the Virus Bulletin tests.
McAfee's VirusScan was another big-name failure of the VB100 certification process. However, when PC Advisor spoke to the company it told us that it is aware of Virus Bulletin's VB100 test results for McAfee VirusScan Enterprise 8.5 and is working with Virus Bulletin on a 'discrepancy' in the test results.
According to McAfee, Virus Bulletin has accepted that it was not using the latest antivirus updates available at the time of test, which caused McAfee VirusScan Enterprise 8.5 to fail when detecting the test viruses. McAfee is currently working with Virus Bulletin on this discrepancy and to make the updated test results available.
