just use 64bit os if you have more than 5gb and you are in video editing or CAD etc. so if you have 4gb or less better use 32bit, 99% no worries. 64bit os is the next future but in real enterprise world, 64 it still lagging in compatability and there are more 32bit users than 64. after a day, i updated kaspersky and scanned again the mlwarebytes installer and voila! the installler has been tampered with trojans. thankfully i run it using sandboxie and then i noticed that it planted files in system32 folder and also added registry files unrelated to malwarebytes and also 3 files were opened before installation. there was this virus which hides itsel to a malwarebytes installation ive downloaded not from the official site, and kaspersky said it is clean. sandboxie lets you run applications in virtual. back way before im using it with vista and kaspersky. Prevent wear-and-tear in Windows by installing software into an isolated sandbox. Viruses and other malicious software that might be hiding in your email can’t break out of the sandbox and can’t infect your real system. Browsing history, cookies, and cached temporary files collected while Web browsing stay in the sandbox and don’t leak into Windows. If you run Web browser under the protection of Sandboxie, all malicious software downloaded by the browser is trapped in the sandbox and can be discarded trivially. So when you throw away the sandbox, all the history records and other side-effects of your browsing disappear as well. Traps cached browser items into the sandbox as a by-product of normal operation.Intercept changes to both your files and registry settings, making it virtually impossible for any software to reach outside the sandbox.Sandboxie changes the rules such that write operations do not make it back to your hard disk. The data is then processed and displayed, and finally flows back from the progam to the hard disk via write operations. When you run a program on your computer, data flows from the hard disk to the program via read operations. It prevents them from making permanent changes to other programs and data in your computer.

Sandboxie runs your programs in an isolated space. An isolated virtual environment allows to control testing of untrusted programs and web surfing. There you can run or install all applications without permanently modifying the local or mapped drive. It creates a sandbox-like isolated operating environment.
