Couple days ago my hp laptop attacked by so many variants of virus, then I scan it with anti virus. Was fpund so many then it deleted automatically by the a-virus..

The day after it, I open up my laptop and surprised, it start up about 6 minutes, and badly after ran a programs , it hang out..

I thought there were so many application gone by the a-virus, for example system restore found not in its place it should be alias deleted,

Do you have any suggestion for it??
Firstly I got idea to format it but there are too many programs installed,,

I would go to malwarebytes.org and download their free antimalware, do the updates, then scan and remove the red ones that show up.
If it won't download because of the virus, download onto a CD on another machine and run on yours, may need to change boot order in bios.
Windows Security Essentials actually works pretty good, down load, update, and scan.
Delete Temporary Internet Files, Cookies.
You may have to go to Tools, Internet options, Connections, LAN and be sure automatically detect settings, some worms set a Proxy to disable IE.
