A virus can slow down your PC, corrupt files or delete them altogether. If that happens some technicians may tell you to forget about data, format your hard drive and start afresh. But that may not be necessary if you keep a new antivirus handy and follow these steps:
1) Close all the programs and fire up the antivirus you have installed [If you don’t have any, skip to step 3]. In the antivirus scanner settings, enable deep mode scanning. You may see a “warning” that says this process is slow; ignore it. Now, look for the action option-what to do if a virus is found. Set this to Quarantine, and do not set it to delete just yet. Start the scan and leave your computer alone until that’s done. You could even turn off the monitor.
2) Turn monitor on. If scanning has finished, open up the quarantine report, and see how many files have been quarantined: the dangerous ones. Even if nothing comes out of this scan, proceed to next step.
3) Shut down and restart. Keep the F5 key pressed [For some computers it is F8 key] while starting to bring up a list of Startup Options. Choose Safe Mode. Once in Safe Mode, you will see a message telling you some programs won’t work. Click OK.
Once restarted, insert the antivirus CD-don’t use a pen drive for this-and install the new antivirus. Once installed, run deep scan again. It will be faster this time because the PC is in Safe Mode and most of the infected files are already in quarantine.
6) If you see some more files, move them all to quarantine and then shut down the computer. Restart normally.
7) Go online and update the new antivirus. After that, run a full scan again. It may find more threats, but that’s unlikely with a new antivirus.
Your PC is now safe
