Hi buddies, I have spent more than 3 months to find a security solution to protect my pc. I trialled so many programs both the single ones and the suites, but I haven't found any that fulfill my expectation. Properly, I'm kinda strict for evaluating them. What I'm concerned are feeling safe and performance. Some programs such as: - Kaspersky AV/IS 6,7, - Trend Micro IS 2007, - Norton AV/IS 2007, - Mcafee 3 in 1, - Panda IS, - Symantec Client Security/ CE - and so on... They make me feel really safe, however they are so heavy on my system. For example: - Some of them like Kaspersky, Norton don't impact Windows start-up speed but they do make my system perform the tasks slowly (opening a program or download/upload the files); - Some of them make my system perform the tasks quickly, but they do impact Windows start-up speed like Mcafee, Panda, Symantec. - Some, like Trend Micro, fulfill both of situations (fast windows star-up speed, fast performing the tasks), but they are consuming a lot of memory and the CPU usage is getting high so easily. I decided not to use the suites but installing AV + firewall separately. I trialled some AVs + firewall such as: - NOD + Comodo/LookNStop, - Avast free/Active Virus Shield/Antivir + Comodo/LookNStop They are so light on both Windows startup speed and System performance, however I don't feel so safe with them (I don't know why ) Anyone please help me to figure out the solutions regarding to above situations. My laptop specification: Pentium M 1.5 Ghz ~1.2 G of Ram Windows XP professional SP2 Thanks!
