i am curently running comodo free firewall version 3.12, g-data antivirus 2010 (trial-planning on buying it if its good-would welcome any comments abt g-data), spybot S&D version 1.6.2.0, superantispyware version 4.29, sponsored adblocker version 1.0.

Note: superantispyware doesnt run in realtime protection mode....i use it optionally once a week or if i have doubts abt an infection. I run the rest of the prgrams in realtime protection mode.

So far (since last 2 days-thts wen i changed my system config and reinstalled my OS)  i havent had any problems yet. There isnt any memory leaks or runaway processes eating up my pc unless i m running a scan on g-data, superantispyware or spybot (guess it is expected during scans) I find this bunch of programs is better than ZA suite i had been using for yrs.

I am kinda paranoid about getting my pc hacked into by sumone (i have a hunch my pc got hacked into a few times cuz i got errors wen checking in emails and im which said i was logged in two places) ......and about viruses and spyware so i am using this mix of programs for my security.

My questions: Do these programs work well together? Is it ok to run them alongside eachother? Will they keep me safe? Is g-data antivirus good? cuz i plan on purchasing it if it is good. Is it safe to use Blocklist Manager (BISS) along with my firewall application? Can i use them on a pc running vista or windows 7?

I dont like Norton cuz of ram and cpu hogging and problems with other antispyware programs etc etc. I havent used kapersky or Mcafee dunno if they hog up system too like norton and ZA or not.

I have used Avast and really liked it :) If i have to change any programs i may go for avast or alvira antivirus and online armor or outpost firewall.

My system: Toshiba satellite M70-131 laptop (yep its a old one but works well) windows xp sp2, 512 ram and the software i have mentioned above. :)
