Hello
Yes, I would uninstall it. 1. Click on View -> Toolbars -> Deselect ICQ toolbar.
or
2. Click on Start -> Settings -> Control panel -> Add/Remove Programs -> Scroll to ICQ Toolbar -> Click delete. This option will permanently remove the toolbar from your system.
Not because it is malcode as such, but there were vulnerabilities with it.
Security problems found in the ICQ Toolbar v1.3 may allow attackers to
control and change configuration settings and to inject scripting code
in RSS feed contents and execute it in the contetxt of the feed
interface (IE's Local Zone)
I
ICQ Toolbar 1.3 for Internet Explorer is a Browser Helper Object that
provides several features including: search, pop-up blocker, ICQmail
notifier, RSS feeds and others. The ICQ toolbar, is one of the various
products offered by ICQ and it is available for download at
hxtp://download.icq.com/download/toolbar/
A problem was found in the way the ICQ Toolbar implements its web
configuration interface that lets attackers controlling a malicious
website change the ICQ toolbar's configuration settings without users of
the ICQ toolbar for Internet Explorer noticing that an attack is taking
place.
Additionally, Cross Site Scripting vulnerabilities in the RSS Feeds
interface could allow malicious RSS feeds to execute scripting code in
the context of the Feeds interface, and allow attackers to access (and,
in specific cases, change) configuration settings.
f that happened in the past, I would not trust such a BHO for the future either.
