AVGRSSTX.DLL looks to be part of AVG Internet Security
Do you have this installed?
If so, you could try uninstalling it, and then restarting and then re-installing AVG Internet Security
If your AVG Antivirus has expired you could also run the AVG Remover Tool: http://www.avg.com/filedir/util/sup...
And download and try Free Avira Antivus instead: http://www.free-av.com/
Let me know how it goes :)
