Having a problem with IE9 after deleting sweet time IM addon I keep getting IE launching, I've run AVG scan and the appropriate MS Malicious spyware removal tool but each show no infection.

I've run Hijack this, see attached log:

I would welcome any advice

Set your default browser to another browser and see if the other browser keeps opening. If so you are narrowing the problem down to a malicious piece of software launching a webpage. You can change the default browser by right clicking on a saved html file and using the "open with" option in the menu. Make sure the "always use this program" box is checked.

I had a similer problem found out it was an add on causing it go to tools/ add ons / open them and disable them all see if it still happens then.if this solves the problem then enable add ons 1 at a time untill you find the one causing the problem hope this helps

Try downloading Malwarebytes and Superantispyware (both free).

Run Malwarebytes first - click on "Quick scan", if it finds anything click on "Show results" and remove - reboot if asked to do so.

Repeat the process with Superantispyware.

Let us know how you get on.

Andy.

Not to worry man, it is an adware sweetIM, its a notorious browser hijacker that causes frequent web redirections, anyways, since it dose not go away by unnstalling through control panel, you should try removing it with the help of a legit anti-malware. AVG wont remove it, dont know about MSRT, but try malware bytes or hitman, you may also check manual removal instructions online
