Problem mith my computer

Without any details on your configuration it is difficult to specifically point out the problem. Almost all antivirus software tends to slow down the computer. But kaspersky do not slow down the computer that much. If you are using vista then immidiately change to XP. It will save you space and increase speed. Since while updating Kaspersky your machine is getting very slow I guess you are low on RAM and Processor speed. Upgrading them might help as well. Give me a little more details about your configuration and I can help you a little more.

You may have low virtual memory or you have to many programs running on the start up hope that helps.

First, you have to check your hard drive where your system is installed. Check if it has still free space at least 1 gigabyte or about 3 to 5 gigs. If it doesn't have, just delete some the unneeded files on it and it should make the difference. If it has enough free space, maybe you're just opening too many applications that your virtual memory cannot handle.
