Hello guys, the topic is too large to be written in the title. I want to ask members round here. 2 years back i was using DIAL-UP with WinXP professional installed. And believe me i hadn't installed any security softwares like firewalls,AVs or anti-spywares. And i was using that dial-up from 2003. So, for 2 years i used that computer without any security. And once i had installed AVs and firewalls too but got no security alerts from them. Checked my system with all possible softwares for hijacks and malwares but found none except some tracking cookies....I tried ZA for 2 months on that conection. Merely 10-50 attack attempts were blocked. Now, i hv broadband connection of 2Mbps. When i got it two years back i tried using it widout any security softwares installed as i did previously. But within 10-15minutes my WinXP Pro became infected. Tried this more than 30-50 times by reinstalling windows XP pro. But same thing happened. So, i was compelled to use security softwares. Actually i dont want to use these softwares as they use too much system resources howsoever advanced system u have. and second important thing for hating these kinda softwares are they bring down by connection speed too much. Now, for example just 8days ago i hv reinstalled ZA. And till writing this thread it has blocked more than 17,000 . I dont understand why Broadband is more affected than dial-ups. Are they only due to high speeds? or something else might be the case with me? I hv a old PC. I like testing it for the time it takes to become infected with no s.softwares. . Maxm. time was 12mins. all other installations were infeted in less than that time. Drop ur suggestions here. And with above statistics is it safe to use Windows firewall. I m currently using ZA but planning to remove it as it slows connection speed.
