Lightweight Security for Windows

We all think alike. We want to keep our computers secure, but we do not want to use those extreme resource-consuming anti-virus or anti-malware programs. We basically do not want our computers to slow down to stay secure.

We have an option: We can employ lightweight security tools, and still stay secure (maybe not as secure, but good enough for most cases). I highly recommend the following two programs:

SpywareBlaster: Secures Internet Explorer and Firefox for free against known malicious websites to keep your computer uninfected.

a2free (a-squared): Free anti-virus and anti-malware detection and removal tool. The free version does not provide real-time protection, which means your computer will not slow down unintentionally. The scanning engine is good and very fast. Just run quick scan once in a while, if something is found, maybe try smart scan, and if you still suspect something, you can do a deep scan. You can also scan a single file or folder from the context menu.
