Hi and welcome to the Daniweb forums :).

Look for, and delete, any program segments (prefetches) that might be present, and are associated with the 'problems' we're trying to remove from your PC. To do this, let's:
1) Click "Start | Search", then search for each of these program's base name(s), in all files and folders:
SLA9.tmp*
2) Then if any are found in the 'prefetch' folder, delete them.
Look closely, since the 'base' name will have a bunch of random numbers and letters attached to it.
===============
Run HiJackThis then:
1. Click "Open the Misc Tools Section"
2. Click "Open Process manager"
-
Next, while holding down the CTRL key, locate (if present) and click on (highlight) each of the following:
C:\DOCUME~1\user\LOCALS~1\Temp\SLA9.tmp
Now double-check and make sure that only those item(s) above are highlighted, then click "Kill process". Now, click "Refresh", check again, and repeat this step if any remain.
===============
Scan with HijackThis and then place a check next to all the following, if present:
O3 - Toolbar: (no name) - {E0E899AB-F487-11D5-8D29-0050BA6940E3} - (no file)
O3 - Toolbar: AVGTOOLBAR - {A057A204-BACC-4D26-9990-79A187E2698E} - (no file)
Now, close all instances of Internet Explorer and any other windows you have open except HiJackThis, click "Fix checked".
