卡巴斯基专用卸载工具下载
卡巴斯基是一个不错的杀毒软件，但由于占用占存和系统资源巨大，很多人不得不忍痛割爱，按正常的卸载方式是不能完全卸载成功的，这也导致了第二次安装卡巴不能安装成功或者安装其它杀软时出现问题，针对此种情况，卡巴斯基发布了官方的卸载工具KAVRemover。
这个卸载工具可是卸载所有卡巴斯基反病毒软件.什么6.07.02009版本，网络安全6.07.02009版本都可以卸载的.
打开KAVRemover，它会要你输入一个验证码来验证是否正确的，然后才会开始卸载，最后是重启电脑。
下面还有一个卡巴斯基官方强制卸载工具，此工具需要在安全模式下运行。
注意：
此卸载工具需要安全模式下运行
该工具默认是你的卡巴安装在"C:\Program Files\"，如果你的卡巴安装在其他盘需更改路径。
更改路径方法（仅个人意见，不是官方说法）：用记事本打开avp_remove.cmd，把C:\Program Files\改成你的安装路径，然后存成.cmd格式后运行。

如何在Discuz7.0侧边栏加广告
DZ侧边栏确实很爽啊，不过想放广告的，可能不是每个人都会的哦，这儿给大家分享一个简单的方法
比如在最新主题下面加广告或者你删除只要你的广告也可以
<div class=”sidebox”>
<h4>最新主题</h4>
<ul class=”textinfolist”>
[node]<li>{prefix}{subject}</li>[/node]
</ul>
</div>
这儿就开始放你的广告代码
如果你不要最新主题，是用其他栏目的调用单独改成一个纯广告调用那么就用这个方法
<div class=”sidebox”>
<h4>最新主题</h4>
<ul class=”textinfolist”>
这儿放广告代码，原始调用就删除了。
</ul>
</div>
另外，为便于广告管理，大家可以用JS来管理，这样代码处直接可以放这样的代码
<script src=”/ad/46860.js” type=”text/javascript”></script>
然后JS文件中写
document.writeln(”<iframe scrolling=’no’ frameborder=’0′ marginheight=’0′ marginwidth=’0′ width=’468′ height=’60′ allowTransparency src=/ad/468×60.htm></iframe>”);
468×60.htm这文件里就放你的广告代码，这样的放法GOOGLE，阿里，百度都支持的。
大家可以看下我改的，并且不影响速度的哦！
