1. for antivirus -- get AVAST, AVG, or AVIRA (all three are free, get the one you like best ... only one antivirus is needed, DO NOT GET MORE THAN ONE!!)

2. Turn off the windows firewall, it's junk. get comodo firewall instead --> http://personalfirewall.comodo.com/

3. Get superantispyware --> http://www.superantispyware.com/

4. Get malwarebytes' anti-malware  (http://malwarebytes.org/mbam.php, download link on left side)

Superantispyware and malwarebytes' have free and paid version, no difference in either except in free version, you have to do everything manually, like the scanning and the updating and there's no realtime protection.

5. I would have ccleaner and advanced systemcare on your pc.

That is your pc army to keep your pc in good shape, in my opinion.

And you list 0.099GB of ram> are you sure you have that number right> 0.099 GB is approx  99 megabytes you know.

avast runs it-self you can stop it the odd night if you want to

run ccleaner twice a week

Well, just find an antivirus that you like, is automatically updating at least once a day and has realtime protection. (AVIRA, AVAST and AVIRA all do it and all three are free and fine for average user and so find the one you like best if you want to go the free way  )
