I have had problems with Mozilla Firefox & Thunderbird. I ran Spybot S&D - it found a problem with Windows Security Center .AntivirusDisable Notify & I opted to fix. CW Shredder found & removed cws.Qttasks but trying to update CWshrredder so far unsuccessful. I do have browser function now but still no email via Thunderbird .am wondering what to do now. I would post a HijackThis (AS A .TXt attachment) - but , trying to boot in safe mode results in the system freezing after a screen or two of files loading. After trying to check for update CWS it was difficult to shut down - Task manager failed to end tasks & I had to power off. Any ideas?
