Last night, I had a recent problem with a virus that was detected and infected 15 files on my computer, according to Avast Home 4.8, with all the latest program and virus definition updates. According to Avast, I have "gotten rid" of the virus but then I have also scanned my computer with SpyBot, updated to all the latest definitions and such. I have also used "Dr Web Cure It", after researching the forums and seeing that other people have fixed my first problem after using it.

My problems are as follows:
1) Avast Antivirus icon does not show up on taskbar. Not the a, not the i. Neither is present even though the processes are running.

2) When I try to save a file, such as an image (I assume everyone saves them by right-clicking and clicking save image as), it does not show the Save To window. It's almost as if it came up but was closed so quickly that I cannot even see it.

3) In the past, when someone sends me a link via AIM or Skype, I click it and it opens as a new tab on Firefox. After the virus attack last night, it opens up as a completely new Firefox window.

4) Popups come up even though SpyBot reports no spyware remaining after my most recent scan (approx. 10 minutes ago). Often, these popups come up when I google search and I click on a link on the page. Instead of opening the page I want, it opens up a new ad. I then have to click back and click the same link again to get the page I was originally looking for. The popups are not limited to this but most often occur through this method.

Please help me!
