The first thing you should be aware of is that running two (or more) anti-viruses is often a receipe for disaster.
Never install Kaspersky without uninstalling previous installations of anti-virus software, it's not recommended by Kaspersky:
http://www.kaspersky.com/faq?chapter=17070...p;qid=169326413.
General removal instructions:
1.Uninstall the anti-virus(es) you have installed via add/remove programsin the controlpanel, then reboot after the uninstall is finished.
2.Next you delete the folder most likely left behind after the uninstall,use explorer to open "Program files" and delete the folder of yourprevious AV, if you get a "In use by other persons or programs" thentry to use a program called
Unlocker(free), simply rightclick on the folder and choose "Unlocker" for youroptions to appear. Very useful tool for difficult files/folders btw.You can also use "Search" in Windows to hunt down & delete anyfiles/folders still there after an uninstall. Another thing you coulddo at this stage, is to run a tracks-eraser to remove files not usedand just using HD space, two free tools are:
CCleaner (both builds with the Yahoo toolbar and versions without this)3.Now would be a good time to use a registry cleaner, there are manydifferent vendors, but the one which i find most thorough and safe is
RegSupremerun it (use normalmode only, not aggressive), when finished scanningyou rightclick and select "All", then you click "Fix" at the bottom, itwill ask you if you wish to make a backup and you do, just to be safe.
Mostvendors make removal-tools for use after removal via add/removeprograms to remove registry entries/folders, you can contact thesupport of the AV in question for a copy.
Removing Norton (even when it is already uninstalled via add/remove programs)Nortonremnants is often a source of problems when installing Kaspersky, theseproblems can vary from small and perhaps unnoticed by the user tryingKaspersky for the first time and therefore thinking that it is normalfor Kaspersky to be a little heavy because this is what he/she reads onsome forums, to very severe slowdowns prompting the user to perhapseither contact support or post here at the forum.
Well, the goodnews is that Norton make some very good removal-tools and if you followthe suggestions below, even if they may seem overkill to you, then abetter experience with Kaspersky can almost be guaranteed and withbetter overall system performance to follow in most cases too!
The"bad" news is that you have to uinstall not only Norton AV, alsoSystemWorks, firewall and antispam if you use any of these (these canbe installed again when everything is done, just not Norton AV ofcourse!), however your patience and hardwork will be rewarded with amuch better systemperformance.
If you had 2003-2007 installed you will need the Norton removaltool. You download the tool from
here.
You are also encouraged to use a general registry cleaner like
RegSupreme,this will find and remove a lot of things so don't be alarmed if thenumber of problems found after the scan is several hundreds, thisnormal, most of them is harmless, but there will also be some which isfrom old installations uninstalled long ago, just let it fixeverything, it will ask if you want to backup and you want this, justin case. Download a fresh copy of
Microsoft Windows Script for XP .......or
Microsoft Windows Script for W2000 (Vista users should skip this step), Norton sometimes messes with this during an uninstall, so you may as well update this too.
1. Now you uninstall Norton via add/remove programs in the controlpanel, then reboot after the uninstall is finished.
2.Next you delete the folder most likely left behind after the uninstall,use explorer to open "Program files" and delete the folder of yourprevious AV, if you get a "In use by other persons or programs" thentry to use a program called
Unlocker(Free), simply rightclick on the folder and choose "Unlocker" for youroptions to appear. Very useful tool for difficult files/folders btw.You may find folders from programs you have deleted long ago, you mightas well delete them while you are in there anyway. You can also use"Search" in Windows to hunt down & delete any files/folders stillthere after an uninstall
3. Now you run the Norton removal-tool.
4.Run RegSupreme (use normalmode only, not aggressive) and fix what itfinds. (rightclick after scan is finished and select "All", then click"Fix" at the bottom or rightclick again & select "Fix")
5. Reinstall Microsoft Windows Script and reboot. You're now finished and can install Kaspersky.
(Vista users should skip this step)
