justhijacked, it would help if you used a secure browser.. with "internet explorer," that would mean using high security-settings for the "internet zone" and the "intranet zone".. with "firefox" it would mean using "firefox" with the "noscript" addon..
using "firefox" with the "noscript" addon is what i would recommend rather than using "internet explorer" with high security-settings.. it is a lot easier to allow "scripting", when needed, when using "firefox" with the "noscript" addon than it is to add websites to IE's "trusted sites" zone, but that is an option..
i used IE, with high security-settings, for years, but i switched to using "firefox" a couple of years ago (after microsoft took too long to patch a vulnerability in IE, though it was finally patched, about a week after i switched to using "firefox" ).. still, like i said, using "firefox" with the "noscript" addon is a lot easier than using IE, with high security-settings..
also, i would recommend not having "java" installed.. most malware-infections, for the past couple of years, have been caused by java-exploits.. that is likely how your computers were infected with malware, by java-exploits ie by "blackhole exploit kits"..
another thing that might help would be to use the "foxit" PDF reader instead of using the "adobe" PDF reader.. if you are going to use the "adobe" PDF reader, i suppose that you should use the "X" version.. according to adobe, the "X" version of the "adobe" PDF reader has not been compromised, as far as they know..
like "java", the "adobe" PDF reader is another thing that is targetted by exploit kits, like the "blackhole exploit kit".. "foxit" says that their "foxit" PDF reader is not vulnerable to the same vulnerabilities that adobe has had to deal with, with their "adobe" PDF reader.. of course, the "foxit" PDF reader has to be patched, as needed, like every other program..
something else that you could consider would by using a program that can control the execution of files.. "faronics" "antiexecutable" is one such program but, from what i have heard, a lot of people have problems with using that program.. "EXE Radar", from "novirusthanks", is another program that can be used to control the execution of files, and it is not very expensive..
another option is..some firewall's apparently can control the execution of files.. "privatefirewall" is one.. i think that the "comodo" firewall also controls the execution of files.. there might be others, too, like maybe agnitum's "outpost" firewall.. from some posts that i saw in the "wilderssecurity forum", many people there tried using "EXE radar" and, apparently, it worked OK for them, but, from what they said, "privatefirewall" does the same thing so they just relied on "privatefirewall" to control the execution of files rather than using "EXE radar" along with it..
in my opinion, the internet is wrecked, with all of the bad stuff that is going on, with thousands of new "websites" (including hacked websites) popping up every day, distributing malware.. if anything, you need to use a browser that is secure, like "firefox" with the "noscript" addon..
p.s. i don't fool with google's "chrome" browser but, if you use it, from what i have heard, it has some security-settings buried somewhere deep within its settings-options.. so, if you use "chrome", my advice is to dig and dig and dig and dig until you find the security-settings and to adjust them for high-security, if possible..
p.p.s. "sandboxie" is another security-program that you could consider using..
