I recently got this virus on my computer that at times seems to be undetectable by my Symantic and AVG virus protection while at other times is identified by Symantic as the Downloader virus. I've also run ad-aware and spybot but everything comes up cleared. The symptoms of the virus include browsers randomly opening up, without my command, and also when I do a search and click a website listed, random search engine home pages and advertisement listings open up instead.
Could it be the downloader virus?
If it is the downloader virus, why does it return even after having been deleted by Symantic?
... To make matters worse, my laptop won't hibernate anymore. May it be that the virus is constantly running?
I know there are many other virus protection software to download but my computer is running sooo slow, I want to be sure the software will be what I'm looking for before I download just anythiing.
Any advice would be really appreciated... I don't want to let my laptop go :(
